Summer Weather, Flight Delays and YOU.

You can see the weather plain as day. But it’s miles away, right? How could that cause flight delays? Or worse, on a day that’s clear at the airport–yet your flight shows a one hour or longer departure day. Why?

Think big–or at least think far: miles translate into minutes in the air, and unlike your car on the freeway, we’re not creeping along under the storm–we have to get through it. At altitude, sure, we can go around weather or sometimes, even over a storm. But there’s the problem on take-off and landing: we are too low to do either.

First, let’s look at departure:

Sure, the weather is nearly twenty miles away. But in flight time, we’re talking about maybe three minutes. Then what?

Normally, there are at least six eastbound routes available, but as you can see, due to the weather that extends from the north to the south, even twenty miles away, there are only two routes available to go east: straight north, or straight south. And guess what? They’re the same ones that will have to be used for the inbound aircraft–and they’re already in the air, many for over three hours inbound from the east coast, or up to nine hours from Europe. Guess who rightfully has priority on the clear routes?

Here’s more bad news for your outbound schedule:

All of the departures–like the one pictured in above, and depicted on the navigation display with the radar image above–have very specific instructions for headings, altitudes and even speeds. But with the weather blanketing the area, no jet can comply with these very orderly instructions, so instead, air traffic controllers have to issue all headings and altitudes individually to each aircraft, checking to be sure that weather doesn’t interfere.

So the Air Traffic Control system must space jets by ten, sometimes ever twenty miles in trail to allow for the individual handling required, which means that instead of the usual interval of thirty seconds to a minute between launches, now takeoff will have to be 2-3 minutes in between.  You’re number ten for take-off? Count on at least 30 minutes, maybe more–especially if the weather arrives over the field while you wait.

So, rather than have a traffic jam at the end of the runway waiting to take off, ATC issues all aircraft an “EDCT” (Expect Departure Clearance Time), or “edict,” as the acronym is typically mangled by crews, or even “wheels up time” in more common usage. This can usually mean an Air Traffic Control imposed delay on your pushback from the gate of forty-five minutes to an hour or more.

That presents another problem: while a delayed flight is held on the gate, the next aircraft scheduled for that gate will be delayed as well, either in the deplaning of passengers or the boarding of its next segment. At a major hub for any airline, there aren’t enough extra gates to make up for flights that must be held on their departure gates. If you arrive at the terminal and notice about double the normal amount of passengers milling about–that’s why: their outbound jet is waiting while a delayed flight sits on the gate, waiting for its EDCT time to roll around.

That’s what happens on the ground–here’s what happens in flight–which actually contributes to the confusion and delays on the ground.

See the racetrack pattern near “CAPTI?” That’s where we’re going to be holding, hoping the weather clears within our allotted holding fuel, which is about 45 minutes. The airport is under the blob of storms at the convergence of all the lines.

The jet we’re flying is being ardently awaited at DFW by 160 passengers who plan to fly on it to LAX after we deplane our Dulles passengers at DFW. But, we’re now on our way–diverting–to New Orleans because DFW is still closed and won’t open for at least an hour.

Add to that the fact that my copilot and I started our flight day at 12:35pm. We leave New Orleans at 11pm, but have to fly all the way to Abilene before we can turn back to the east around the scythe of thunderstorms bisecting Texas. What’s normally a one hour and ten minute flight turns into two and a half hours, pushing my first officer to a 14 hour flight duty day, landing at 2:15am.

Not sure what happened to all the LAX-bound folks, whether they got a crew to fly the leg or not, or what happened to the connecting passengers on our flight arriving after 2am.

All I know is that this promises to once again be another season of crowded skies, summer storms, bone-achingly long flight days and above all, a challenge to everyone’s fortitude and patience. Now that you know the “what and why” of the weather story–maybe you could explain it to the guy seated next to you, wondering why everything is so messed up because of a little old storm?

How Big is the Sky?

The cockpit is a solemn place in the pregnant pause between preflight and pushback. Always, like a deserted island where everything’s already been said: checklists done, preflight complete, systems verified, amen. Plenty more details and decision points ahead, but nothing to worry about now, because the litany of procedures, numbers, actions, maneuvers and control inputs are etched in your mind like an inscription in granite. Thinking about the details is unneeded; knowing what’s to come and when is like running a hand over the inscription without reading the words–and that’s enough for now.

“You have a visitor,” the number one flight attendant breaks the reverie, ushering a school-aged boy into the cockpit. He looked to be maybe seven . . . eight? Dutifully wide-eyed behind thick glasses, a woman–must be his mom–hovering behind.

“C’mon in,” you say. “Are you the new copilot?” You jerk a thumb toward the F/O. “Because he’s pretty useless. You can do a better job–you ready?” Covertly, F/O gives you the finger. You smile.

The young man shakes his head in silence. “Go ahead,” mom prompts. “Ask him.” Then she adds, “He’s usually a chatterbox; loves airplanes. I think he’s a little overwhelmed.”

Good thing I’ve been such a smartass–that doesn’t help. “Sure, ask away,” you say. Stuff about airspeed? Controls? How we operate systems? He fixes you with a flat stare like he was looking right through you and into your heart.

“How big is the sky?”

Now there’s a question I’ve never been asked. And I’m not even sure how to answer.

“Yeah, Captain,” a smirking F/O echoes, “You’ve spent about thirty years in the sky. Just how big is it?”

Hard to say. Seen it when it wasn’t big enough, plunging straight down with a tangled parachute, cows below coming into focus faster than I ever wanted. Had to get a reserve chute out before finding where the sky ended and the earth began and even then, hit like a ton of bricks as if both earth and sky wanted to teach me a lesson about leaving one for the other.

Other times, the boundaries hardly mattered; gravity, the speed of sound–just mileposts on the way to somewhere higher, farther, faster and more furious than anything else in the thinnest parts of the sky. Those times felt like you were bigger than the sky itself, bulletproof and immortal.

But then you’ve seen it, too, when it was too large, swallowing up a past or a future, a passage never to be undone.

Because when it is, the sky is mute but bears the passage anyway, indifferent: coming back? Gone forever, though you thought not.

There’s a road through the sky for that too. Too big, too far, but crossing the blue was a choice to be borne nonetheless. And if the sky were time, you’ve seen it too short, knowing some folks are making a one way passage . . .

. . . while others are only now setting out on their first. We’re all in the same sky, big or small as it is. You can ask the question, but the answer depends.

“I mean,” a small voice breaks into the suspended moment of thought and silence. “I mean in case we fall.” Big eyes, in all seriousness, all seven or eight years looking ahead and asking.

You just can’t worry about that. In fact, it wouldn’t matter anyway–we all go where we must, take the sky as it comes, cross it where we can, while we can. With those close to us or alone, however we must. Shepherded by mom today, shepherding his own tomorrow.

At the speed of sound on his own, without wings if he wants (bad idea, trust me), to new worlds and old, forward as we all go through the blue till it dims to black.

Smile. “We won’t,” you tell him. “You won’t, and we won’t. So let’s go fly.”

He thinks about it for a moment, his eyes searching, but not on me; elsewhere, maybe finding a place for the idea, judging for himself the size of the sky ahead of him. Mom gives me a look: what, knowing? Ponderous? Then a smile, steering him by the shoulders back to the cabin.

Couple more minutes and it’ll be time: seal it up, push it back, light the fires and taxi, then take off.  How big is the sky?

Well, let’s go find out.

Airline Pilot Confidential: The Teddy Bear Incident.

It’s the middle day of three back-to-back turns–pace yourself.

In fact, it’s the second leg of the middle turn, Dulles International, 7pm–time to get out of town: the elephant walk of international widebody jets commences shortly.  If we can push back even five minutes early, we can beat the line–and the wake turbulence delay.

Use the captain’s invisibility cloak: the ability to do most pre-flight planning on the smart phone. Check the weather, the route, the fuel load. Add more fuel. Sign the release with a touch of the screen, then send a hard copy to a gate printer, all from the cockpit. Wait for it to finish printing then slip into the terminal discretely, invisibly, to pick up the paperwork, avoiding the gate chaos directly. Don’t make eye contact, don’t invite hassles, complaints, requests, anything that delays the door slam and brake release to get ahead of the fat boys headed for the runway. Still have to fly to DFW, drive home–then back out to do the turn again tomorrow. Minutes from pushback, be invisible now.

But wait. Out of the corner of your eye, you see it: a teenage girl, on her phone, tense; next to her, what could only be her younger sister in tears. No parents, no adults, just the agent telling them both, “You either board now, or you’ll have to fly tomorrow.” That sends the little one into big sobs.

Less than fifteen minutes till push. Can you maybe say you didn’t see any of this? But you did.

“What do you need?” you ask the older, maybe sixteen-year-old sister.

She puts the cell phone down for a second, plaintive. “She left her backpack at security.”

Sigh. The agent is looking at you pointedly, his eyes saying we need to board now and shut the aircraft door. But from the tears in the young girl’s eyes, you pretty much guess what’s in the backpack. I consider taking the youngster back through security–but then think better of it.

We’d have to run to the center of the terminal, down two escalators, onto the train to the main terminal, up two more escalators, then find the security checkpoint that might still have the backpack–then retrace our steps, before departure time in fifteen minutes. Not going to happen.

I catch the older sister’s eye. “You have some ID?” She nods. “Let’s go.” I head off at a fast walk toward the mid terminal; “Wait here!” she tells her little sister, and the agent slumps the message damn you captain. Big sister’s on my heels, asking, “Can we do this?” Just shrug; “They’re not leaving without me.”

We tumble down the two-story escalator two steps at a time, shoving past others like obnoxious travelers. I envision people watching, trying to figure out why an airline captain in uniform is running away from a teenager in hot pursuit. I also remember the miles I ran that morning before flight.

Even though the automated voice is warning that the doors are closing–do not delay this train–I do anyway, holding the door as she jumps aboard. “It’s got all her school books,” she says, out of breath. Right: I have a big picture of a fifth grader hauling a load of schoolbooks on spring break.

“No worries,” I say, “It could happen to anyone.” She nods. “Special guys in there?” I ask casually. She smiles sheepishly.

I don’t care: that’s a very real tragedy for a youngster, losing all the stuffed guys that mean the world to them. Not on my watch.

We spill out of the train on the far end, then WAIT: this will take us to baggage claim and out of the secure area–we need the TSA checkpoint! We dash back through the closing exit doors, then push through the boarding passengers and out the other side.

Two sets of identical escalators–both going down. Means we have to rush up the steps–but which ones? “Which security checkpoint did you use?” I ask. She looks confused; they are identical, not sure how one could really know anyway. “Let’s try this one,” I say, rushing the steps.

We reach the TSA supervisor’s stand. He shakes his head. “No pink backpack here–try the other side.”

Figures. We run the length of the concourse and arrive at the opposite checkpoint. “You’re lucky,” a cheerful TSA agent in a pressed blue shirt says, “we were getting ready to send it to lost and found.”

Identification checked, signatures. She sees me eying her sister’s backpack. “Uh, we need to start putting a nametag on this, don’t we?”

I nod. Lesson learned. It’s confusing, especially kids traveling alone. “I was on the phone with my Mom,” she says, “hoping we could get someone to drive out here and pick up the backpack.”

“No worries,” I say, in my mind’s eye picturing the waves of 747s and A-340s pushing back, lining up for takeoff.  “Anyone can lose stuff at the airport, especially at security.”

We retrace our steps as fast as we can, me feeling the morning miles, my friend feeling and looking relieved. At the gate, she hands the backpack to little sister who still looks mortified.

They rush down the jetbridge to board. I walk, telling the agent “Just charge me with the delay.” He gives me a glare that says I was going to anyway, which I answer with a smile that says I don’t care.

The elephants already started the parade and we squeezed into the conga line. Sure, I’d have some explaining to do a thousand miles or so west. But no one missed their connection in DFW, no one was unduly delayed; and most importantly, no one’s little world collapsed with the loss of everyone they loved. That, to me, matters a lot.

Because we don’t just fly jets–we fly people. That, and the occasional special bear.

All in a Pilot’s Day: Thunderstorm Zen and the Captain’s Firewall.

Head pounding. Look down at your right calf: a liter bottle of water, mostly full.

Stupid.

Just flew 3 hours from DFW to DCA–should have paid attention to hydration. Now, sitting near the end of runway 1 at Reagan national, it’s too late: the damage is done.

Been sitting here for over two hours now. In a thunderstorm. Which has hit the tower with a lightning bolt that fried their primary radios–so now they’re using a weak backup radio that sounds like the controller is using a tin can on a wire.

More delay while the radio situation gets fixed, plus the hand-offs from tower to departure ain’t working. Wait.

Call the tower: “Tower, American 445.” Wait.

“American 445, go.” Sounds like her head is in a bucket.

“We’re wondering about a take-off time, as we’re bumping up against some Passenger Bill of Rights time constraints.”

Like three hours–an hour from now–then we need to go back to the gate and probably, cancel the flight. Passengers have a right to not go anywhere, rather than sit on a plane waiting to go somewhere.

“We don’t have any information,” comes the tinny reply. Thanks for your help.

Ignored several phone calls from the cabin crew already, saying passengers are antsy, wondering what the latest is. When I ignore the interphone chime, the F/O has to field the questions to which there are no answers anyway. I prefer to isolate myself to focus on weather, fuel, timing, the departure procedure to the north (the FAA will violate you for even a tiny stray from the radial) and a clear path on radar. Which I can’t see because our nose–and our radar dish–is facing south. I make a PA every thirty minutes or so, telling passengers what I know: westbound departures are on hold due to weather on the departure routing. The lady in the tower sounds like her head is in a bucket. I don’t tell them that, but still.

Already tried to negotiate a departure to the south or even east in order to air file a route west–craftily uploaded an extra 3,000 pounds of fuel before pushback, after seeing the storm front marching on Washington as we landed.

No dice.

More calls from the back: passengers want to use their cell phones; they’re getting up . . .

Tell them no–if they use phones, the cabin crew has to make another aisle pass to ensure they’re off for take-off (FAA regulation) and if we’re cleared, we need to take the runway, check the weather–then go.

Sure, they have connections and people waiting. But that can wait till we get there. What I want to attend to is a new and higher power setting that creates less time on the runway; an optimum flap setting that gives a better climb gradient, and a wind correction to stay on the safe side of the departure radial.

That’s where the “firewall” comes in: if I let connections, cell phones, Passenger Bill of Rights or even my own next flight tomorrow (not going to be legal if we keep delaying) mix with the important considerations like fuel, weather, radar, performance and power settings, something’s getting messed up.

It’s not that I don’t care–I really do. But if I don’t attend to the latter set of considerations, the former won’t matter, will they? Drink some water, rehydrate. Relax. Run through your list of priorities for right now. Pay attention to right here, right now. Be ready to do “now” right; worry about later, well, later.  That’s the thunderstorm zen, the captain’s firewall.

It happens fast: “445, start ‘em up–you’re next to go.”

Fine. I reconfirm with the F/O the heading plan (310 is good–but 305 is better. If we have to correct back right to the radial, fine–but we do not stray east . . . a full radar picture before we roll, static.”

Raining cats and dogs, hard to see, swing out onto the runway and grab every inch. Stand on the brakes, full radar sweep–decide.

“You good?” I ask the F/O as a formality–because I’m looking at him and I can tell from his face whether he is or isn’t from his look no matter what he says. And if he isn’t okay or doesn’t look okay, if maybe his firewall or zen are under seige, I’ll know and we won’t go until everything adds up.

We roll; relief when we’re past abort speed; mental chant “engines only, engines only” reminding myself of which of the hundreds of warnings I’ll abort for on that rain-slicked postage stamp of a runway; throttles speedbrakes THEN reverse, amen. The jet rockets into the whipping rain undaunted; love the big fans at a high power setting. We climb, buck, dodge, weave and finally . . . cruise at 40,000 feet above all the turmoil as the lights of the nation wink out.

Landing after midnight, home finally at 1:30am. Crew Schedule calls: “Sleep fast, we’ve slipped the departure of your Seattle turn just long enough to keep you legal. You’re still on it.”

Eight hours in the cockpit today; another eight tomorrow. Plus a few hours to sleep in between.

Erase today–it’s over, safely and smartly done. Rest, and save a little zen for tomorrow. No doubt, you’re going to need it.

Airport Smackdown: Jethead vs. LaGarbage

What better to beat the blistering heat of a Jethroplex summer than a float in your own ce-ment pond? You bid the later-in-the-day flights and you’re senior enough to hold them. That means the morning run–helps you sit still for the 6 or 7 hours you’ll be in the air–and an early afternoon swim. Then, reality check waiting on the iPhone:

You knew that. LaGarbage today, tomorrow too–then LAX the next day. That’s your work week. Get ready.

That’s the current radar picture in the New York metro area. The stuff just north of Tom’s River will be a problem if it doesn’t move out to sea. You can tell there’s a front line between Jersey and NYC somewhere–just look at the temperature difference. Cold air slipping under warm air produces big boomers, and it doesn’t take much of that to disrupt the inbound flow to Kennedy, Newark and of course, LaGuardia. Shrug. Deal with it when you get there–but prepare for it before you take-off: more fuel.

Of course, that’s a double-edged sword too: LaGuardia is a short runway with virtually no overrun on either end–just Flushing Bay. No, it’s not as extremely short as Burbank, John Wayne-Orange County or The Dreaded 33 in Washington (5,000′). But it’s short enough–especially if it’s wet–to make landing weight important. DFW: 13,000 feet of concrete, overruns and clear zones beyond. LaGarbage? A friction overlay on the end of 22 and 13, (wanna test that out?) murky water everywhere else.

Preserve your options: arrive with enough fuel for holding and a go-around. The 737 is a good stopping jet–as is the MD80–and the 737 is very stable on approach. No big worries about airspeed control or pitch.

Confer with Flight Dispatch: they have you flight planned in the mid-thirty thousands because of previously reported chop. Fine, but we’ll check ahead en route and decide if we can’t cruise higher and save more fuel. Plus, our route will arc north, then east, picking up more tailwind as we go. Should put us over upstate New York fat on fuel.

Board 160 passengers. Preflight. Taxi out. Climb.

Life settles down to cruise: fuel flow, ETAs, routing. As expected, the ride is reported smooth in the low 40s by aircraft there now, so we climb and save more fuel, plus put ourselves above most of the weather trying to build itself into the stratosphere from the sun’s climbing radiance.

Radar watch is beginning to turn up signs of the frontal clash converging on the northeast. Super radar–good picture out beyond 300 miles, has it’s own GPS so it knows where all topographical features are and screens them out of the radar image. Good to be sure that what we’re seeing is nothing but weather.

Lunch? Dinner? Whatever–it’s the last food you’ll see today. Everything at LaGarbage will either be closed or out beyond security, which you don’t have time for: they’ll be clamoring to board 160 passengers outbound as soon as you get there. Speaking of which, within an hour of landing, we can get the current weather at LaGuardia and print it out:

Fine. Planning on 22; landing south and into the wind, no real storm threats or complications. Set up nav aids, discuss the approach with the F/O. Verify the runway in the Flight Management System (FMS) and the Heads Up Display (HUD). Validate all of the altitude and airspeed restrictions on the arrival.

The FMS begins its backward countdown of miles to go and upward count of vertical velocity required to satisfy the arrival restrictions. Cool?

Not so fast. Just checking onto a new frequency and you hear holding instructions being given to some unlucky aircraft. Now, that either means someone south of you (Atlanta? Philly?) or someone north (Boston?) has an inbound backup. Or–it’s New York Center airspace that’s enjoying a traffic jam at altitude. You bring up the holding page on the FMS display. Here it comes.

“American 738, hold west as published at MIGET. Expect further clearance at  0115.” Figures. Well, okay–holding endurance? Like you haven’t thought of that already. At altitude, we’re at an incredibly low fuel burn.

We can loiter for the better part of an hour. One thing about EFCs (Expect Further Clearance) you can count on is–you can’t count on them. So plan accordingly. On your side is your altitude, fuel flow and fuel reserve. The jets cruising lower enter holding there and burn more fuel as a result. Set up the entry and the hold:

EFCs are a best guess by Air Traffic Control, but they can be very pessimistic. Even if you can’t hold as long as they predict, you can hold till your endurance runs out and you need to bingo (divert to your alternate). Some pilots I know like to “Go Ugly Early:” if you think there’s a good chance you’ll have to divert, beat the rush for fuel and a turnaround at the divert station.

I’d rather stay high and slow and see what shapes up. We all still divert when you reach Bingo fuel, it’s just a difference in strategy.

New York Center is offering “Rockdale,” a navigation point north of  LaGarbage and in Boston Center’s airspace. Get released from holding immediately and approach from the north is the deal they’re offering, and some jets are taking it. I don’t think so; we have a good, high altitude perch here with a low fuel burn. Rockdale requires a lower cruise, inevitably, with higher burn–and no guarantees when you get there. Sure, maybe Boston Center has less aircraft but you still have to eventually get sequenced into new York Center’s flow.

It’s like switching lines at the grocery store: pick the short line and someone will need a price check or will have a zillion coupons to verify. Meanwhile, some jets below are starting to Go Ugly early–Philly’s going to be a mess. And the winds are shifting at LaGarbage–they’re switching landing runways:

Refiguring the approach is not a big deal. But it’s a bad sign: runway changes take time and lead to a huge backup on the ground at LaGuardia. Plus shifting winds mean unpredictable weather due to frontal passage. Alright, plan “B” is the runway 4 approach. Reprogram the FMSs, the courses and the nav radios.

Holding is eating up fuel, which is actually easing the stopping distance–but check it anyway. And use the chart for a wet runway while you’re at it. Figure on the worst case and the most Autobrakes, say 3 or maybe even max.

More jets at the bottom of the stack are heading for Philly; we’re still sound fuel-wise. Patience.

Finally! Released from holding, cleared downline. Do the numbers: what fuel will you arrive with but more importantly, assuming a go-around at LGA, what will you land with at JFK (that’s the plan) after? Numbers show actually about a 1-2 thousand pound surplus. Perfect.

Now we’re committed–not going to climb back into the enroute sector (too much fuel burn). And now the glass shows what the radar has been painting.

The ugly blotches here are actually the towering cumulus we’re sinking into here:

Already have the crew strapped in, all passengers down. Actually, the bad weather is a relief in a way: everything slows down as radar separation is increased. Plus, the approach is a straight-in, precision approach rather than the hairpin visual approach that is officially called the “Expressway Visual:”

Lots more fun from a pilot standpoint, but definitely more hectic. Finally, the wide swing to finally. Configure. In the slot: altitude, airspeed, configuration, glide slope, localizer.

Minimums: see the runway, land carefully; immediate reverse.

Now, the elephant walk to the gate. Park.

No time for relaxing–it all starts again in 50 minutes, outbound with another 160 passengers impatiently waiting to board. The inbound holding and the LaGarbage ground congestion has already set us behind schedule, and passengers have connections to make at DFW.

That’s the workday–only another 1300 air miles to go. Let’s get to work.

Summer air travelers, beware: he’s out there!

Summer air travelers, beware: he’s out there.

I mean that guy. The one who will make your travel a little less pleasant, probably unknowingly, but still.

For example, cruising at 40,000 feet northwest bound, the cabin interphone chimes. The First Officer and I exchange glances that ask hot, cold, or stupid? It’s too soon for crew meals—that’s where we’re stupid for eating them, but it’s something to do—and only minutes ago someone called to say it’s too hot in back.

Traditionally, within minutes, one of the other four Flight Attendants who don’t seem to be able to talk to each other will call and say it’s too cold.

But I answer the phone and this time, it’s stupid: “We just found a passport in seatback 30-A.” No, it’s not the flight attendant that’s stupid—it’s the passenger who on some previous flight for some odd reason decided to stash his passport in the seatback pocket.

Before our flight, the jet had come in from JFK. Maybe an international arrival, and now someone is enroute somewhere without a passport.

That’s where you come in: you’re in line at Mexican Customs in Los Cabos, and you’re sweating like a fat lady in a vinyl chair, waiting, waiting, waiting—because the guy ahead of you in line talking to the taciturn Customs agent is suddenly aware that he doesn’t have a passport. Your vacation is on hold just a little longer because like me in the super market, you got in the wrong line (“Price check on lane seven!”) while passengers to your right and left are breezing through and claiming their luggage (and maybe yours), heading for the beach.

Sure, it’s going to be worse for him—without a passport he’s not getting back into the United States without a major hassle and, you hope as payback for your delay, a strip search. But the lingering question is, why would anyone put anything of value in a seatback pocket on a plane?

But you’d be amazed at what you’d find back there after a flight. Well, what someone else would find back there: I’d sooner stick my hands into a trash can in a crack den than risk the snot rags and barf bags or kids’ diapers or half eaten ham sandwich that will be stuffed in there.

 

Still, people for some odd reason nonetheless sit down, empty their pockets, stash wallet, iPod, keys, camera, travel documents, passport—you name it, into the seatback pocket as if it were their glove compartment on their family car (okay, there may be a ham sandwich in mine, I admit).

Never mind the hassles going forward to recover a lost item, a headache made all the more difficult because the jet will crisscross several thousand of miles before the discovery of a missing item is made (call the lost and found in Seattle, Chicago and New York). The important thing is that the Stupid One is delaying your vacation.

And unbeknownst to you—he may already have delayed you. Remember sitting at the gate well past departure time? I can’t tell you how many times five or ten minutes from pushback to a resort destination in Mexico or the Caribbean when the agent steps into the cockpit and says “we have a problem.”

Let me guess: someone confirmed on the flight is in a bar somewhere starting on the umbrella drinks and about to miss their flight to the actual resort. Why? Because they can’t read a ticket? Don’t know their own itinerary? Can’t do the math on a time zone change? Are intellectually low functioning and were finished off by the TGI Friday’s Bloody Marys in the airport bar?

Doesn’t really matter. The point is, if they’re not on board we get to sit at the gate while the ground crew sorts through the cargo compartments crammed with the luggage of 160 passengers to pull their bags off. That takes a while. You get to wait, I get to wait, both of our days becomes a little longer.

Yes, it’s the lowest common denominator that dictates when we leave and when you arrive in paradise.

But there is justice in the situation, as I witnessed once at a departure gate as I waited for my inbound jet. Airport police officers had pulled a couple off to the side as passengers boarded a jet for Cancun.

Apparently the man and woman had been to the airport bar, and the man had clearly had a few too many. Federal law prohibits the boarding of any passenger who even appears to be intoxicated, and the airline agents had done the right thing: when in doubt, call law enforcement to sort out the situation in accordance with the law.

Sorry ma’am,” I heard an officer say as the man was being detained, “he’s going to be placed under arrest for public intoxication.”

I couldn’t hear the exact back and forth between the steamed woman and the officers, but in the end, it seemed the officers weren’t the cause of her anger: she grabbed her boarding pass, shot a pointed glance back at her handcuffed partner—then boarded the flight.

Just as well: he’d probably realize in the Customs line in Mexico that his passport was missing anyway.

After the storm: fly home–but not so fast.

After the divert to Wichita Falls, time to gas and go: Flight Dispatch says DFW is accepting arrivals. That’s all we needed to hear–we’re refueled and refiled with Air Traffic Control. As soon as we’re released by tower, we’re in the black night and headed south to DFW at 280 knots.

Would be flying faster, but 280 is the best turbulence penetration speed and though the ride’s not overly bumpy, the latticework of cloud to cloud lightning straight ahead promises roughness. We’re making a beeline for one of the four arrival corner posts for DFW at 10,000 feet.

Things will happen fast on a 70 mile flight, and the First Officer is flying: he’s sharp, and that allows you as captain to oversee all of the preparation, the checklists, the navigation and most importantly, the radar. Approaching midnight, we’re now 12 hours into our pilot duty day, but regardless, there is still the same roster of tasks to be accomplished–and they don’t care how tired you are, they must be accomplished correctly.

Getting a good look at the current radar sweep and things look ugly. The cells have broken up and are scattered like mercury all over the place. The DFW airport arrival information is automated: weather, winds, runway–all printed out from the on-board data link printer. The DFW info says landing south–so you set up frequencies, courses and descent altitudes in both sides of the Flight Management System, as well as both pilot panels. While he flies, you brief the approach.

Have to swing wide around storms–request a descent to get below scud blow-off you can’t see on radar, but which you detect because it’s blocking the pattern of ground lights you know should be Denton. As soon as we begin descent, the master caution light glares in front of your face, along with a pressurization clue. A quick glance at the pressurization control panel above the F/Os head shows we’re holding cabin pressure fine, it’s just that we never reached the programmed cruise altitude and the computer is confused.

“Off schedule descent,” you say, punching off the warning light. Reset the cruise altitude to 5,000, which is lower than where you are, to let the computer recalculate and catch up.

“Radar vectors to 35 Center,” says the air traffic controller. Dammit–we set everything up for a south landing per the DFW info.

“ATIS says DFW landing south,” you say, making sure there’s absolutely none of the annoyance you feel in your voice.

Pause, wherein you can imagine the controller saying to someone the ATIS is wrong. “I’ll check on that, but plan north.

Redo the courses, rebrief for the F/O, reinsert the proper approach in the FMS and extend the centerline for intercept. Complete the checklist down to configuration, validate the Heads Up Display Data. Staring at the lights of The Ballpark in Arlington miles south, doing the math on descent rates versus final turn altitude based on a left turn thereabouts. Looking good.

A loud snap as the autothrottles kick off. “I’ve got them back on,” you say, reaching up to reinstate the system. F/O nods, concentrating on flying.

Now ask yourself why they tripped off. No failures annunciated–they wouldn’t have reinstated with an internal failure. And it’s not that choppy. Has to have been a power interruption. Glance up–sure enough, there it is.

The left generator bus source is gone. Is it the generator or the bus that’s failed? Regardless, we’re flying with only one electrical source–the right generator. Not good.

First instinct is to start the Auxiliary Power Unit (APU), a small jet engine in the tail that can provide electrical power and pressurization air–but wait.

If the fault is in the left electrical bus, adding the APU generator could either cause a fire, or take down the APU generator. Be patient.

Although you know the right generator has assumed the power load–so the bus must be okay–why take chances?

“We’ve lost the left generator,” you say, reaching for the Quick Response Handbook. “I’ll take care of it. “F/O nods.

The procedure confirms what you deduced. Within a couple minutes, you have the APU running and power restored. Follow the QRH procedure exactly; better to have two electrical sources–if you’re down to one, if it fails, it’s going to get dark and ugly: flying with limited instruments and systems on 30 minutes of battery back up. In the weather, at night. We can do it–but would rather not.

Left base turn from an angling downwind. Mike’s doing a good job–he sees the bad angle and is slowing and calls for dirtying up with flaps and gear. The runway’s coming into view on my side. Good altitude and speed; the intercept of glideslope and course will be fine.

Tower calls the winds “130 at 18.”

Dammit. The limit is 15. With the 50 degree offset, we’re close. Legal, but you don’t like flirting with limits. Even on a long runway.

“Continue,” you say to Mike’s inquiring look–he’s done the math too. But you’re just about decided to abandon the approach. But no need to rush anything. Rushing is never good.

“I’ll rebug you to 40″ you say, changing configuration as required by the tailwind, “and brakes 3.” He nods.

At a thousand feet, it’s clear that the tailwind is unstable and variable–you can tell from our ground speed versus the airspeed.

No good. “Let ‘s take it around,” you say. He nods, adds power–the descent stops.

“Here comes flaps 15,” you recite the litany for him,”positive rate, gear coming up. Missed approach altitude set.”

“American 245 is on the go,” you tell the tower.

“Fly runway heading, maintain two thousand,” says the tower.

Fine; nearly there–reset the throttles from N1 to speed, reset both FMC from climb to capture. Reset both course windows and MDA–because we’re going to land south. Reprogram the FMS for the 17s.

“I’m going to teardrop you out to the east, then bring you around for a final to the south,” says the controller. “Can you do that?”

Eyeballing the radar: nastiness to the northeast, but there’s some room.

“Give us five miles,” you answer. No need to rush–make this correct, hit every step. F/O nods. “Then turn us back in.”

Slowing, getting dirty. Left sweeping turn.

“Do you see the runway?” asks tower. You do–you give a thumbs up to Mike. He nods.

“Affirmative,” you answer.

“Cleared visual approach, cleared to land, 17 Right.”

Confirm the Right runway freqs, MDA and courses set. “I’ll bug you back up to 30,” you say, changing configuration again: don’t need a whole lot of drag without the tailwind and with a possible wind shear. Mike nods.

Glideslope is rough. You’re on a hair trigger to go around again–there’s plenty of fuel to hold or go north to Oklahoma City or south to Austin. Be alert, be patient.

Increasing wind; good sign–but it has to stay within controllable limits. Mike’s doing a fine job wrestling the jet onto glidepath. The Boeing is a steady machine–an MD80 would be a bucking bronco in this.

Below 500 feet–you’re call: it’s stable enough, we’re good. If Mike wants to go-around, we sure will, but we’re good.

Over the threshhold, Mike puts it down; speedbrakes deploy, he yanks in full reverse, the jet slows.

“Nice job,” you say, taking over as we slow to 80 knots.

After landing checklists, taxi in. Careful, do the job right all the way to the chocks. Engine shutdown.

Passengers deplaning, our shutdown checklists complete. You’re writing up the left generator in the maintenance logbook, a mechanic is already on the jetbridge waiting.

“You can take off, Mike,” you say, “I’ll finish up here.” Meaning you’ll do the final “after all passengers have deplaned” checklist items to power down the aircraft. That’s a courtesy you do–you’re the captain, you leave last. He did a great job tonight–respect that.

We fist bump, he leaves.

You finish up: packs off, recirc fans off, cockpit power off. Grab your bags. Slip out of the gate area past the 160 passengers who have no idea what transpired between Wichita Falls and their safe landing a few minutes ago. Nor should they–that’s what they pay you for.

Fresh air feels good, outside waiting for the employee bus to the parking lot. Nearly 1am, got to get home and get some rest–flying again tomorrow.

Summer Storms, Airline Flight, and YOU as Captain.

Well that’s going to be trouble, your air sense tells you as you wing westbound.

Because you have to turn around and come back once you reach LAX–and this stuff, you can feel it: it’s growing. In a few hours, it will stand between you and “homeplate”–DFW for you–and it will be your job to thread the needle between, above and around the towering wall of what will be full-blown thunderheads by the time you return.

But the weather-guessers say the storms will stay south and west of the Jethroplex, right?

Yeah, my ass. Sorry–been fooled before. Now, we deal with gut feel and radar. Forecasts? Farther out than a couple hours–pretty well useless. Keep flying.

LAX, first stop: got to have a cup of the strong Brioce Bakery coffee. Kind of crave it flying to LAX. Westbound passengers happily herding off; First Officer about his business on the ramp, catering, cleaners. You?

Stout cup of Brioce and radar, your best friend. Which helps you set up your next best friend: jet fuel.

But here’s where your air sense–and 17,000 flight hours–comes in: the storms forming up and marching west to east aren’t really a front passage. Rather, they’re a boundary collision that the cold front is barely strong enough to move. Those storms will stagnate wherever they form–my best guess–so there’s not going to be a quick close-then-open, 40-50 minutes of holding.

Hedge your bets: approach from the northwest in fact, route north over Albuquerque and see if you can beat the frontal passage, or be positioned to slip in immediately after. Plus, from behind the squall, all of your divert options will have a clear path. So in this case, northern route, an hour of holding fuel, see how it plays out.

The first round of bad news comes up on the data link printer in Arizona: “0300 DFW tempo 1ovc tstm lgtctcctg 34012g25 29.77 prsfr.”

Duh: “airport expecting one hundred overcast around 10pm in thunderstorms lightning cloud to cloud, cloud to ground; winds from the north gusting to 25, surface pressure falling rapidly.”

Trouble in front of the front. Cross the Rio Grunge eastbound, nice tailwind rocketing the aluminum tube across the ground at 500+ miles per hour.

My F/O is smart, sharp, quick. A good asset in forming a plan, then a backup, then another. I like options. I choose my words carefully: “Hey, you want any coffee? I’m buying?”

I like the way Angela makes coffee, the old-fashioned DC-10 technique: a splash of club soda on the bottom of the pot before brewing–eases the acidity, gives a smooth flavor. Hell, no rush here–I hate redoing stuff. The radar picture won’t be too well defined until about 300 miles out, even better at 160. Have a cup of Boeing brew and relax.

Okay, now we’ve got something to work with. Did I mention how much I love the 737-800 radar? It has its own GPS system, always plotting where it is–and it knows the terrain everywhere it finds itself and miracle: it screens out ground clutter–and does its own tilt for each range. What you see is what’s there–how cool and smart is that?

This picture is looking southeast. The blob over HIKAY is the nasty storm cell headed for the airport. As I figured, we’ll either beat it, or the airport will close–and it did as we approached 100 miles out. We expected that.

The good news is that we’re assigned a holding pattern over Wichita Falls. Sheppard has a couple of long runways and jet fuel available. Once we’re established in holding at 33,000 feet–a good altitude for fuel economy–I call the Sheppard tower on another radio: how late are you open tonight? How late is the fueler open?

Eleven o’clock for the tower, all night for the fueler. It’s just after 10pm. We’ve got fuel for 40, maybe 50 minutes of holding, then we need about 4,000 pounds to fly north to Oklahoma City.

But we’re right on top of Wichita falls/Sheppard. I can see it–perfect weather. No additional fuel for the divert–we just spiral down.F/O concurs. We start setting up navaids, approaches.

Our holding racetrack--right over an excellent divert spot.

DFW approach updates the airport re-opening projection: midnight.

The mass exodus begins from various holding stacks because no one has that much loiter fuel. Most on the north side are heading for Oklahoma City.  “Put Wichita Falls on request,” I tell the F/O, as we continue all divert prep and logistics with our dispatcher in Fort Worth.

We exit the holding stack northbound with a descent clearance, all of the divert notifications and nav system reprogramming done, approach briefed–we’re way ahead. The winking lights of two jets above us in the pattern suggest what I’d be thinking if I were them: “Smart bastards–first into Sheppard, first for fuel, first out.”

Yup.

Sheppard Approach: “Plan runway 33 center.”

Me: “Unable.” The center runway is 150 feet wide; our wingspan is around 130. The left runway is 300 feet wide–but the Air Force is using it for night traffic patterns in my ex-girlfriend:

Tough darts, wingnuts: when it was me in the Air Force flying the White Rocket, I’d have said tell the civilians to get lost–we’re busy here. Now, with 160 passengers and a crew of 7 on board, I think differently.

I’m doing the math, checking the descent rate and speed and distance–it’s all coming together nicely, “in the slot” as we say. Over the threshhold, follow the HUD cues projected before me on the glass; little narrow-gauge skid marks from smaller jets slide under the nose, then touchdown.

Clear the runway, set the brakes for a minute–whip out my cell phone and call the fueler, “Landmark Aviation.”

“How much fuel do you need,” asks a friendly voice. We have 5,800 pounds on board, I’d wag 3,000-4,000 to get to DFW, 3,000-4,000 more for delays. Plus some more thousands for peace of mind and the unexpected, two factors that usually don’t work well together.

“We need 12,000.”

“No problem, taxi on down.”

Tight maneuvering on narrow taxiways and a small transient ramp, but slowly, carefully, watching the wingtips–we park. I see the lights of two other airliners approaching from the south. Hah! The fuel truck is already here.

First Officer is outside, doing the exterior inspection. I’m on the phone with dispatch for a clearance plan, on the radio with tower for a proposed launch window, then with DFW approach for an expected route, then the phone again for current DFW weather.

My fuel guess is pretty good: dispatch wants us to have 15,000 pounds of fuel–we have 17,500. I love jet fuel.

Me signing for six tons of jet fuel.

Behind us, a Super-80 waits, an Airbus waiting behind him. I chat with the MD-80 captain in the quaint Wichita Falls terminal–he needs to have flight plan faxed to him; we printed ours on our on-board data link printer. I considered for a moment suggesting the dispatch send his to our jet, but I’m not even sure that’s possible. And we’re ready to blast off.

Supposedly, the terminal folks are on their way back and they’ll fire up the FAX machine for him and his 140 passengers. Too bad you ain’t on the Boeing, I thought but didn’t say.

Carefully, point by point, we check our route, then our performance data. Never mind that it’s nearly midnight, 11 hours into our workday–every single detail will be checked. I will see and he will crosscheck every number put into the performance system.

We start engines, a ground man pulls the chocks and salutes: clear to go.

I have a better idea. We sit with brakes parked and accomplish all pre-takeoff checklists so that I don’t have divided attention taxiing out over the mini-sized taxiways.

Tower clears us for take-off. One last check of numbers–the runway, the rotate speed, the weight, the power setting, all check out. Stand up the throttles, all exterior lights on, punch the take-off power button on the throttles and she leaps forward with a growl.

Off the nose, black sky, more storms; cloud to cloud and cloud to ground lightning weaving a brilliant latticework to the south, where we’re going. Dead ahead, more spot decisions, plans, backups, numbers, radar and ultimately, maybe a cup of coffee to go for the drive home once we navigate the weather gauntlet.

But nothing’s set in stone; we’ll just see what’s what when we get to DFW. The coffee and DFW will just have to wait, but I’m patient, and careful. All in good time–despite all pressures to the contrary, all passenger and crew urgency, fatigue; I tune it all out. Every step carefully, thoughtfully–that’s what summer flying is all about.

Quite a light show in the DFW terminal area, and the hurdles spring up one by one, then in droves. Weird, but I kind of like the challenge. But that’s another story.

Summer Air Travel: 3 Things You Need To Know.

You’re traveling by air this summer? Good. But there are a few things you should know and be sure of BEFORE you get to the airport. And, of course, some shortcuts and time-savers and more things you should be aware of once you get to the airport to avoid an ugly surprise on check-in.

Because it’s not enough to just show up on time any more. In fact, without attending to the things I list below, you’re really gambling with your trip and whatever you’d planned at your destination. Airlines typically have higher load factors in the summer, which means fewer seats available on every jet, and this summer has started with record-breaking crowds vying for seats.

Combine that with tight customer service staffing and you have the makings of a travel headache–which is preventable. Read on.

1. Get your seat. Yes, I know: you booked your flight. That’s not the same thing as having a seat. Made your reservation on-line? Be sure there is a specific seat listed–and check again 48 hours prior to departure. I can’t tell you how many times I’ve been at the gate, trying to look inconspicuous, as an agent tries to explain to a passenger that no, they don’t have a seat assignment–and the flight is overbooked. Often, when reservations are made way in advance, there’s isn’t a specific seat listed–or between “way in advance” and the day of travel, the seat assignment disappears. To prevent that: print your boarding pass at home with the seat assignment–don’t wait until airport check-in. If you don’t see a seat assignment on your on-line boarding pass–get on-line and reserve a seat, even if you have to call the airline’s toll free number to do so.

2. Know your status. That is, are you protected from cancellations or delays? If you have a deadline at your destination–say, a time sensitive event (wedding, graduation, business meeting, etc) or follow-on reservations (a resort or cruise booking, or flight on another carrier), what  protection do you have in the event of a delay or cancellation?

Be aware that most airlines offer compensation or modified travel in the event of situations within their control (say, flight cancellations or mechanical delays), but most people don’t seem to know that airlines and federal regulations do not stipulate any accommodation for weather-related delays or cancellations. Thunderstorms at a major hub, in summer–what are the chances? Pretty darn good, unfortunately. And along with rain, hail, and damaging winds, storms usually bring delays, cancellations and misconnects.

Are you prepared to sleep on the floor of the terminal if weather delays you inbound and the last flight of the day to your destination has already departed? Don’t plan tight connections–or in my opinion, any connections to the last flight of the day, for exactly that reason. But if you must, be prepared to find an airport hotel on your own or, sleep in the terminal. Ugh.

One further note about “knowing your status,” and this is important: did you buy your ticket from an online source other than the airline itself? If so, read the “conditions of carriage” before you agree to the purchase of a ticket: many of the larger online travel sites sell bargain basement seats–but they are for a specific flight, with no recourse if you miss the flight. In other words, the deeply discounted seat does not come with any airline follow-on obligation–that’s how the online site got the cheap pricetag they sold you on. But again, if you misconnect for any reason, your travel is over.

No “stand-by” on the next flight or travel at another time or date. You agreed to buy a particular seat on a particular day and if you’re not in that seat when the plane departs, you have no further recourse with the airline–and good luck with the online agency you booked your travel through.

In both of these cases: trip insurance. It’s not that expensive and may be your only way to protect yourself from large out-of-pocket expenses due to missed bookings and events at your destination, or overnight delays enroute.

3. Damage control: when things start to go haywire due to delays, weather, cancellations or diversions, you need to act immediately. Before you leave home, do two simple things to ensure that you’re first in line when it comes to salvaging your travel plans.

First, sign up for whatever notification app your airline offers. Not only will this automatic function give you an immediate heads-up on your assigned gate and departure time via text message or email, many major airlines will also notify you of a cancellation or significant departure or arrival delay long before the delay appears on monitors in the terminal.

Why is that important? The advanced notice will allow you to find the next available flight to your destination and then pursue a confirmed seat before your fellow passengers even know there’s a reason to change. First come, first served when it comes to accommodating passengers from a cancelled flight.

Which brings us to the second must-do: pre-program the airline’s re-booking number into your phone for quick access. The re-booking number is NOT the same as the reservations or flight information phone numbers. Find it on your airline’s website or call their toll-free number and ask for it, then keep it handy on your trip. The alternative to calling the re-booking number is to stand in a long line of irritated passengers waiting for a few agents to fix things one at a time. Skip that–get on the re-booking line at the first sign of trouble.

Want to play Superman? Turn your cell phone on as soon as allowed after landing. You’ll be notified by text or email of any cancellation on your itinerary–then you can call the re-booking number on taxi-in and start damage control to save your trip. Same goes for the hours before your origination–keep listening for the text alert regarding your flight. Even if things go well, you’ll want to know what gate you’re scheduled to depart from. In all cases, have your reservation info handy for re-booking–an agent on the phone or face-to-face can access your itinerary instantly if you can provide the record identifier (usually a series of letters and/or numbers) on first contact.

It’s going to be a busy summer for air travel this year, with record crowds and limited customer service options in the case of weather-related delays. But these three simple steps will put you well ahead of the crowd all rushing to rebook flights or deal with a delay. Secure your seat, know your options, stay informed and be ready to rebook.

Number one above–seat assignment–is even more crucial if you’re traveling with others and want or need to sit together. Number two, know your passenger status and your options. And finally, line up your damage control options and beat the rush to re-book or make changes as the situation develops.

Once you’re on board and we’re off the gate, your work is done and I’ll take care of the rest of the flight. And as I say after every welcoming P.A., “Sit back, relax, and enjoy the flight.”

The “Whys” of Airline “Ground Stops” For Passengers

For many passengers, flying is an unfamiliar, sometimes confusing experience made all the more so by the lack of understanding of inconveniences like ground delays.

Often it seems such take-off delays are arbitrary (the sky is clear and blue; let’s go!) and unfounded–but if you understood the reasons behind departure delays, you could at least keep your blood pressure low and your patience intact.

The most common–and often dreaded–delay term you might hear regarding your take-off is “Ground Stop,”  which means you are not being allowed to take-off or more succinctly, your flight is stopped on the ground at your departure airport.

Why?

Multiple reasons. The most common is that the destination weather is such that the the number of inbound aircraft the Air Traffic Control can sequence is restricted or reduced.

Why? Well, the most common problem is a low ceiling and visibility that requires expanded spacing between aircraft.

Why more spacing? Because if we as pilots can separate ourselves from other aircraft visually on an approach and landing, we need only five miles of separation. If we’re flying in reduced visibility, that separation requirement at least doubles to ten miles. That cuts down the number of arrivals possible per hour.

But it could also be a beautifully clear day and capacity could be limited by winds. If the wind velocity or even gusts approaches the crosswind limitation of most aircraft–normally around 30 knots–then some runways may be unusable.

Why? This happens at DFW now and then because of the seven runways, five are oriented north-south, two are northwest to southeast. Doing the math, two runways rather than seven handling arrivals will of course mean delays.

The Ground Stop is a temporary way to shut off the flow of inbound aircraft until such time as either the limiting condition dissipates at the destination field–and that could be the low ceilings and visibility, winds or a thunderstorm. The last problem–a storm–can also cause a ground stop for your destination even after it passes.

Why? Sometimes it becomes a question of real estate: if a storm at your destination has stopped their outbound aircraft from taking off, there often is simply no room to taxi and park a slew of inbound aircraft. This is particularly true at small, congested airports like LaGuardia and Washington Reagan, but even large airports like DFW can become gridlocked as well.

And if the condition slowing things down is icing, there really is no point in allowing too many aircraft in.

Why? Because once an aircraft is de-iced, a take-off must be accomplished promptly or the deicing fluid loses its effectiveness and the plane needs to be de-iced over again.

What about when you’re told there’s an “outbound Ground Stop” for your airport? Rare, but it happens.

Why? From a pilot standpoint, the airport isn’t exactly “closed.” But the problem becomes the departure corridor: if the radar controllers can’t find a clear path for departing aircraft, they simply don’t allow any departures. But sometimes when your airport’s weather is fine, the departures from another nearby airport might cause a temporary shutdown of your airport’s departures.

Airways crammed into the east and northeast.

Why? Well, as in the case of JFK, Newark, and LaGuardia, or Baltimore, Washington, and Dulles, or Chicago O’Hare and Midway, DFW and Love Field, or San Francisco International and Oakland and San Jose, and LAX and any of the dozens of airports there–if one field has bad weather, particularly thunderstorms, their inbound and outbound aircraft have to maneuver off of the normal routing in order to avoid thunderstorms. Air Traffic Control will wisely limit the number of new aircraft added to the mix.

On-board radar display: no take-off clear path.

Really, a Ground Stop makes sense when you think about it. Because the limiting condition at your destination would still exist whether you take-off or hold on the ground. So the problem with allowing the take-off even though the landing field is restricted is that you end up with a larger risk of delay.

Why? Because if the delay inbound is absorbed in the air, that means holding. If holding time is projected to be over a half hour or maybe even forty-five minutes, the end result will be a diversion.

Why? Well, because there’s only so much fuel we can carry en route since every aircraft has a maximum landing weight. If you add an extra hour’s worth of fuel–about 10,000 pounds on my jet–but then it turns out that you don’t need it to hold enroute, you could easily be too heavy to land. Guess what happens then: you will get to hold until you burn off the excess fuel, which is a tremendous waste and will guarantee that some connecting passengers’ next flight will depart without them.

Plus, in my pilot mind, after about forty minutes of holding, my air sense tells me it’s time to find a better place to land. It’s simply not prudent from a pilot standpoint to arrive at an alternate without extra fuel for contingencies there. And if we do have to divert, depending on how long my crew and our duty day has been, the FAA may mandate that we’re done flying for the day–which means you are too, wherever we are.

But all of that can be avoided by holding on the ground at our departure airport, burning no fuel. As frustrating as that may seem, the alternative is actually worse and really, taking-off without a good probability of being able to land at your intended destination doesn’t really sound like a good idea, does it?

I have to say, some crewmembers don’t even understand all of the Ground Stop factors I just explained and certainly, most passengers don’t either.

But the wise passengers like you who understand this “big picture” explanation of the dreaded Ground Stop can just take a deep breath, nod wisely and be confident that they’re on the optimum route to their destination.
