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?

Flight Crew Talk: The Beatings Will Continue.

What we have here . . . is a failure to communicate.

You wouldn’t think it would be so hard for crewmembers to communicate in flight–we have the technology; interphone, PA system, headsets and handsets–even our oxygen masks on the flight deck are wired for sound.

Nonetheless, once the cockpit door is closed, communication dies a slow, miserable death and as captain–it’s YOU taking the Cool Hand Luke beating from the Road Boss.

You don’t like it, I don’t like it–but that’s the way he wants it . . . so he gets it.

Let’s start with what’s usually the first salvo, fired right as we climb through ten thousand feet. That’s the magic end of “sterile cockpit,” which is the time period when flight attendants know non-essential communications with the pilots is prohibited because it’s a phase of flight requiring our concentration in the cockpit, and distractions are not welcome. I have answered the crew interphone when we’ve received a call below 10,000 feet with the admonishment, “We’d better be on fire if you’re calling me now.”

But above ten thousand, here it comes: “Can you turn down the air?”

Sigh. What does that even mean? More cold air? More hot air? Higher temperature? Turn down? So begins twenty questions: “What is it you want?” Sadly, though, the whole thing is our own fault or, honestly, usually the F/O’s fault.

That’s because F/Os just CANNOT LEAVE THE TEMP CONTROLS ALONE. This is especially true of those with lingering brain damage from the MD-80, which essentially had a caveman vintage air conditioning system that DID require a lot of tweaking. On take-off, at full power, it could make snow in the back if you didn’t nudge the temp control valve off of the full-cold stop.

Not so with the Boeing–but F/Os HAVE to mess with it anyway–even though if the temp was comfortable on the ground, the Boeing will maintain that in flight.Nope–F/Os have to mess with it, have to do something, even though automatically, it’s fine left alone.

And that brings on the second failure to communicate. Inevitably, the F/O has to argue, usually tossing out, “Well, the duct temp says 75 degrees.”

Unfortunately, the crew interphone system is a party line, and the flight attendants are listening. Sigh. They don’t give a damn about the duct temp–neither do I–they just know if they’re comfortable.  But that’s the pilot pigheadedness: we already know everything.

To reiterate, as I bump all three compartment temps down, just leave it alone, and give them whatever the hell they want. What do you care? You’re not back there.

Plus, use your head: this is a senior turnaround flight, with senior flight attendants swathed in layers of polyester, hauling carts and traipsing up and down the aisle. You think they want heat? You think I do? Sitting in the gazebo, direct sunlight–I constantly reach over and call for more cool air. You’re cold? Too bad–next flight, bring a sweater.

Now, let’s visit the cruise portion of our non-communication. The primary voice passengers hear is the PA, which announces information pertinent to our flight, like arrival time and weather. That’s key information for travelers and crew alike. But, there’s a catch: flight attendants can’t hear the PA.

For flight attendants, the PA is like a dog whistle: we can all hear it, average dogs that we are, but flight attendants are oblivious. You could have just said over the PA “we’ll be landing in one hour” and within minutes, the interphone chime will go off and the question will be, “When are we landing?” And not just once, because not only do flight attendants not hear the PA, they don’t talk to each other either. So you’ll get the same call two, maybe three times.

And never mind that you’ve given them a hard copy of the flight time before takeoff, and that they’ve typed that information into the touch screen at their station controlling the passenger information and entertainment system . . .

. . . and that touchscreen, if they look at it, will tell them how much longer we have left in the flight. But, that would mean they’d have to look at their watch, then do the math. Especially when we’re landing in a different time zone–it’s easier to just call up front and ask me. Right?

Well, maybe not me. My answer is usually relative: “About ten minutes early.” Which means: look at your watch. This is your flight–know your own schedule.

Or, look at the gee-whiz panel at your station, counting down the minutes. Or, do the unthinkable: ask one of your colleagues in the back? Nah. Whether it’s the temperature or the time, rather than ask each other, just call up front. All of you–not one call, but four, because you can’t hear the dog whistle or talk to each other. Even had a fifth flight attendant, just riding the aft jumpseat home 130 feet behind me, ask me to “cool off the back.” Seriously?

Okay, it’s a given: we work together, fly together, even all talk–sometimes at once–to each other. We just don’t communicate very well. So, my new policy is this: any time the crew interphone chimes, I look to the F/O and say, “It’s for you.” He’s the one screwing up the temp anyway.

And at least I’m happy, and that’s a start.

Tales From The Flight Deck

Back in the day, you’d slide that DC-10 electric seat forward in the copilot’s position and hunker down for the long haul: 9 hours from DFW to Paris on a good day with favorable winds. But more than flight time or miles or fuel flow and track routing, pacing was the order of the day: you’re going to be sitting here all night–don’t be in any rush to do anything.

That was over twenty years ago–closer to twenty-five. And the captains in those days had at least that many years with the airline in order to have advanced seniority-wise into the widebody left seat ranks, rarified air in any airline. So we’re talking what–a half century into the past, into the flight memories and aviation lore to be shared in the cold, dark, midnight sky over Greenland and the Atlantic?

Always liked flying with Bob C., now deceased, but who in those long hours at altitude would relate memories of flying wing for Iven  Kincheloe over the Yalu River during the Korean War. Barely hanging onto his wing, trying not to get killed . . . he was a madman . . .

But tonight’s story hour would come from a different source. Dick B. had flown Super Connies for TWA before quiting to take a job with my airline when I was still in pre-school. “A better deal,” he’d always say, “although flying plumber on the Connie was a heck of an education.”

Plumber. Or, in more correct parlance, flight engineer. Back in the fifties, he’d say, the airline biz was a whole ‘nother animal. Of course, we all still say that: when were you hired? Ninety-one? Well, all through the eighties this airline was a blast . . .

Still, even with a grain of salt or two, the Kinchloe or Connie stories were a welcome relief from the doldrums of midnight cruise across the pond.

Tonight Dick was holding forth about the early Connie days, back when the Cold War was heating up; the days when a lot of guys like Bob were just out of the Air Force after the post-Korean War draw down. Guys like Dick had never served, so he’s been able to spend his early years on the engineer’s panel instead of hanging onto Iven Kinchloe’s wing for dear life.

Those were the days of Kruschev bellowing about the demise of democracy, and Sputnik, and the nuclear standoff. In the midst of it all, both countries at least made a show of diplomacy. That’s where Dick came in.

Besides the well-known “red phone” from the Kremlin to the White House, other lesser gestures intended to defuse the Cold War took place as well.

Aeroflot would be allowed one flight a day into “Idlewilde Field”–later renamed Kennedy International–in New York City, and one U.S. carrier would be granted a landing slot in Moscow. A small but meaningful attempt at detente. The U.S. flag carrier granted this Moscow route was, of course, TWA; and the aircraft making the maiden flight was the Super Constellation. On board was one very young, excited flight engineer named Dick.

It was common knowledge that the Aeroflot aircraft would be packed to the gills with spying equipment like cameras and other electronic data gathering devices. Maybe that’s why Kennedy was chosen as the landing base by the U.S. State Department: nothing to overfly, no way to take spy photos out there in the Long Island hinterlands.

But in the spy vs. spy paranoia of the Cold War, the Connie crew just knew they’d be spied on once they landed in Russia. So, Dick told us, when the crew reached their layover hotel in Moscow, they made a pact: they’d all search their rooms for the listening devices and spying equipment they knew had to be there. Dick tore apart his room and found nothing–but in short order, his phone rang: the lead flight attendant had found a mysterious metal canister under her bed.  Aha. Be right down with my tools.

The good flight engineer grabbed his tool bag and hustled to the flight attendant’s room, already packed with the captain and the rest of the crew, with the bed shoved aside, mysterious, gleaming canister in the center of the floor.

Carefully, using a crescent wrench adjusted for the odd caliber of the nuts on the bolts ringing the canisters, the engineer removed each bolt carefully. Suspense built with the last bolt . . . deep breath, lift the canister . . .

Nothing.

But within minutes, there was an angry voice at the door, fists pounding, and footsteps rushing down the hall and towards the room. The crew prepared for the worst.

Instead, it was the maitre d, enraged, plus the hotel manager. As it turned out, the flight attendant’s room was above the main dining room. Instead of disabling a sinister spy device, the crew had unwittingly removed the anchor plate for the chandelier in the dining room.

Oops. maybe Kruschev was right–maybe Americans were the real crazies, despite the world famous pictures of him pounding the podium with his own shoe at a televised news conference. And my question, though I didn’t ask, is whether the red phone on Eisenhower’s desk rang shortly afterward, with a demand for payment for one smashed chandelier and maybe a buffet line.

But those days, and those pilots, are now long gone. Now, in the left seat, it’s pilots like me remembering them, but also our own early days with the airline and the adventures that span thousands of air miles.

And when it gets dark, and quiet, and dull on the flight deck at 41,000 feet a thousand miles from anywhere, it’s time.

Did I ever tell you about that time in London when the police picked up the entire crew walking down the middle of the street at 3am?

And so it goes . . .

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.

Breadcrumbs in the Jetstream.

Used to be that in your first few hours of acrobatic flying that you had to consider how a meal would taste not only going down–but also coming back up later. Never, ever forget or underestimate the return trip.

Just like scout camp: on the way out, remember that tree, the rock formation–picture how it’s going to look coming back on your way home. So flying eastbound, you keep in mind everything germane to your westbound return.

Isobars in the back of your head as you’re outbound. Big kink in the jet stream over Arkansas, and you know what that means: lesser wave to surf eastbound, but lesser tide to buck flying west. But you can already tell what’s going on after about thirty minutes of flight. As you expected, the big dip pivots over Arkansas where it’s mixing Gulf moisture gathered from the south with the coldest air from the north.

Messy. But no worries eastbound–we’ll top it, for now. Other eastbounders won’t and it doesn’t hurt to pass the word back: looking better toward Walnut Ridge outbound to the northeast. The moisture’s making its stand here in southern Arkansas and looks to be planning to stick around. The kink in the jetstream isn’t going to sheer off the tops because it’s weaker–100 knots versus 150-160–when it courses straight out of the west.

Which means, for our return leg, bet we’ll need the southern arrival while this troubled air mass beats up the northeastern cornerpost into DFW. And since we can see that the jetstream velocity is less, no real problem coming back high in the 40,000 foot range instead of ducking under.

Air Traffic Control relays the National Weather Service warning that already rolled off the datalink printer in hard copy: level 3 thunderstorms with hail and possible tornadoes over Texarkana. Which is right below us. And no kidding–our radar shows the hook-like purple edge that I’m sure we’ll read about in the morning paper: somebody seven miles below is looking at a wall of towering cumulus and likely, a twister screwing itself into the earth west to east.

But it’s all quiet up here. Ground stuff, groundling speed and flying dirt mean nothing at altitude–but the whole ugly mess gets stored away for future reference westbound. Which starts on the ground in the east.

The old trusty Farmer’s Almanac of the sky thinking, the intangible notion my friend and the ultimate aviator Randy Sohn like to call “salt,” and I hope is “air sense:” no delays outbound, no crimp in the airway from planes deviating south. We’ll approach from the south, but will plan for at least one big reroute within the last 200 miles because the mess over Arkansas isn’t dissipating no matter what the National Weather Service predicts.  So here’s the fuel load that will work–ain’t what the system planned,  but it’s what I want. And what we’ll get.

Hours later, at 38,000 feet, the change comes: “Fly direct Little Rock for the arrival.” What? Could the ugly mess be moving south, and that fast?

Here’s the direct Little Rock view: is it really moving south fast enough to justify the extra mile to double back to the north? If not, we’re throwing ourselves into it with fuel we don’t want to waste. If so, who’s not glad we have extra fuel on board? Thank you Farmer’s Air Almanac brain and Randy’s salt, we have the burn available–because the thunderbumper gang is moving like a freight train. Here’s a picture five minutes later and the storm has raked itself ten miles south:

Remember, we’re just looking at the tops, radar auto-tilting down, and the ridge of thunderstorms is thundering like the mounted cavalry across central Arkansas, slashing and burning like Sherman on the march. We have plenty of cruise fuel and again, a silent, smooth ride high above the fistfight of Gulf moisture and the northern jetstream. Ringside seats. Quiet, smooth ride. Follow the breadcumbs, leavened with salt. Amen.

That didn’t end well at the surface. But, that’s why we try to pass so quietly above. And why no one on board is any worse for the wear or wiser for the passage. Which is why we fly jets in the first place, right?

The Pilot Poser: Silence is Golden.

You’d only know this if you’d been in the cockpit of an airliner. And I have been–for almost 28 years now.  Over 21 of those years as captain.

Sooner or later, you’ll have to fly with “that pilot:” the one who is impressed with himself, and more importantly, his impression of himself. The “self” he assumes others see, but in real life, something else is apparent.

Seriously?

Unfortunately, “that guy” craves recognition. May have the awful bumper sticker on their car proclaiming “My other car is a Boeing;” they need to be seen in aviator sunglasses (never owned a pair), have to wear a gawd awful watch the size of Flavor Flav’s clock (flight attendant bride gave me too nice a tank watch for me to ever wear the cliche), and of course, off duty they dress like the calendar says the present year minus twenty. They can be ex-military (if anyone asks, I always answer, “No–I was in the Air Force;” big difference.) or all-civilian types; regardless, the arrested development crosses both borders.

Worse than “the pose” is the time warp they cling to. They’re mired in the “Married With Children” Al Bundy “There I was . . .” thing, yammering on about the glory days (Al was always telling his dusty-ancient Polk High School football team stories) and here’s why it’s BS: even though the median pilot age at my airline is probably 50+, you’ll see the stickers on the kitbag of the military squadrons they once belonged to–even though they haven’t flown a military jet since the pilots now actually flying those jets were in diapers.

“There I was . . .”

Sigh. It’s going to be a long trip. They tend to emphasize appearances, which really only matter in public–which is actually the last place I want to be “a pilot:”  I prefer, as do most of the pilots I respect, to be mostly invisible in public. Here’s where I’d rather be an actual pilot:

Where it actually matters. Where other actual pilots respect you for doing a good job, for knowing your stuff, for being dependable. Behind the closed and bolted shut (thank god) cockpit door, where all that really matters is how you perform.

And at that, too, there’s a further preference:

“Can we have a little ‘shut up’ around here?”

Archie Bunker said it best. There’s just not a whole lot of yapping that needs to go on in flight. My favorite type of First Officer is the person who says little, who concentrates on what needs to be done. Don’t want to be lectured about politics, or harebrained and ill-informed (pilots are always the last to know) investment and stock market schemes. Or, God forbid, religion, which somehow is always associated with extremism, anti-feminism, home schooling and weird “Yearning for Zion” cultism.Odds are overwhelming that there’s an oprressed, decidedly frumpy and tired spouse at home dealing with your plentiful “offspring.”

Want to talk baseball? Maybe. College football? Sure. But please God, don’t trap me on the flight deck with the Rush Limbaugh wannabe who’ll parrot whatever was most recently on NPR (the sure sign of geriatric “lost the will to live”–and think: listening to NPR) as if it were original thought. And labor-management strife? I’ll say it out loud: this is neither the time nor the place . Besides, you’re preaching to the choir. Take it up later with your dog who might not mind hearing you rant.

It’s a relatively small space up in the pointy end–and nothing makes it seem more cramped or the hours longer than a large and ceaseless yap. Captain or First Officer–and I’ve been both–nobody needs to be a blast fence (see “labor-management strife” above), comic foil or sounding board for the other person also locked into the cockpit.

So, outside the cockpit, feel free to go for “the look,” the pose, whether you’re a pilot or not (probably worse if you are–get over it). Walk the walk, yack the yack (NPR and union parrot talk); knock yourself out. But inside, respect the inner curmudgeon lurking in the the quiet, uniformed figure in the other seat. The best pilots, or at least the ones I’d want fly with, are all about quietly doing what makes good air sense rather than yapping about it. And the key word is, quietly.

Jet Wake Turbulence: Distance Ain’t Enough.

Sneaking up behind me, are you? Here’s an infrared view you might need to heed: not the hotspots, but powerful the twin horizontal corkscrews of air current swirling off the wingtips of my jet. They’re wily, dangerous, and not to be trusted.

According to the Flight Safety Foundation, the vortices from a jet can have an internal rotation of up to 300 feet per second and often extend between 2 and 10 nautical miles behind a jet aircraft. The twin tornadoes–that’s literally what they are, horizontal but spinning powerfully–sink at a variable rate, between 300 and 500 feet per minute to an altitude  between 500 and 900 feet below the aircraft’s flight path and can persist for three or more minutes depending on the meteorological conditions.

That’s the problem, but hardly the full situation. Add to this hazard the closely constrained flight path of jet traffic in terminal areas. For instance:

Approaching from the east, you’ll have a traffic stream from the west as well converging on the same runway complex. Not unusual as far as airports go–except that San Francisco International has less than the standard distance separating the two parallel runways. The FAA has waived the normal lateral separation, but you’d better keep that in mind nonetheless because that also means less than normal separation from the vortices of the aircraft next to you. Remember the outward spreading motion of those two tornadoes?

This guy could be your dance partner all the way down final–and if he’s next to you, you aren’t entitled to the separation you’d get if he were ahead of you. Mostly, ATC will “advise” you to “use caution” for the heavy on the west runway, workload and time permitting–but they don’t have to.

And time and workload may not permit any advanced warning, and adverse weather can shroud the entire scene anyway:

Look at the inset on the bottom right corner: Seattle (one of my favorite destination cities!) has three parallel runways grouped together, and you won’t be told which of the three runways you’re landing on until you turn base to final about three minutes from touchdown. Would it make sense or even be possible to keep you informed of the heavies on all three inbound tracks? Add to the mix the typically obscured Seattle visibility, plus the added workload of programming and validating the FMS  sytem approach waypoints at the last second demanded by the late runway assignment and is there a possibility of situational awareness overload, on final approach: was that a heavy in front of us? Or on the outboard runway?

Bring that back to San Francisco, where the standard runway separation is “waived,” like in MSP and many other cities. Now you’ve got a “buddy” laterally whose wake turbulence is drifting outwardly–just as yours is–and just because he’s not a “heavy” doesn’t mean he can’t roll you.

The ICAO worldwide “recommendation” for separation between a “heavy” and a “medium” following aircraft  (say, a 747 and a 737) is 5 NM (9.3 KM); between two heavies, 4 NM (7.4 KM). But the wild card not even mentioned in the separation rules is configuration and maneuvering: simply put, a “dirty” jet (flaps, gear) creates a nastier wake than a “clean” jet, and maneuvering distorts weight. That is, if I level off my 160,000 pound 737 with an addition one-half “G” force, I add to the effective weight another 40 tons of effect. And we’re a medium jet–imagine a heavy maneuvering dirty adding to his effective weight and wake.

That’s the science, now here comes the art. You know the reported winds at the field, but that’s a red herring: your encounter with wake turbulence won’t happen on the field. You need to be aware of the winds on approach, at your altitude. If the lateral wind at your altitude is blowing into the other jet’s wake, here’s what can happen: if the drift equals the outward spread momentum of the wake–and you have to figure the “dirty,” “maneuvering” wild cards mentioned above–the effect will either be to move the wake away more rapidly, or freeze it in place till it dissipates. Which is it?

You can’t see wake turbulence. You can’t be sure where it is, or know it’s strength based solely on the aircraft designation. And sooner or later, you’ll find yourself in it despite your best, most diligent precautions. What are you going to do, captain?

For a true jethead like me, the first answer is always speed–but not so fast (pun intended): you’re configured with restrictive maximum flap speeds. If you’re in a final configuration with 40 degrees of flaps, you’re limited to 162 knots max. But the second instinct is valid: power.

But power alone is only part of the answer: what you’re not doing is going down. Why not? Because we know the vorticies are sinking. If we remain level or climb, we’ll escape the effects. What are they?

The Flight Safety Foundation survey of hundreds of wake turbulence encounters reveals uncommanded roll in trailing aircraft of up to 45 degrees at altitudes below 1,000 above the ground. One thousand feet is another magic number at my airline: stabilized approach  (on speed, on altitude, power set) is mandatory from 1,000 feet to touchdown. On glidepath–not above or below; not accelerating or decelerating, power set to flown speed and stable. And certainly wings level.

Which brings up the next problem of two major headaches you’ll instantly own. First, the right amount of counter-aileron, even if applied prudently, in many jets will bring up the wing spoilers to drop the low wing rapidly, inducing adverse drag, requiring more power.

Second, the option of climbing or even flying level is constrained by the published missed approach: protected airspace may be below you if you are above the missed approach altitude. And laterally, not only is there often parallel traffic, there’s also dangerous terrain you must always monitor and stay clear of:

If you encounter wake effects in a level portion of the approach segment, prior to the aircraft ahead descending, at least you know his vortices will descend eventually below you and in this case, you normally feel the “burble” which now cues you: if the winds are keeping his wake aligned with your flight path, on glidepath you’re likely to fly into the tornadoes again when you’re slow and configured with speed-restricting flaps. Now look at the “mileage separation:” still think distance alone is enough? Still committing to the glidepath?

All of that doesn’t even consider the added, inevitable spoiler in every approach: weather. There’s more than terrain and aircraft for you to avoid in a very constrained airspace.

There’s really only one good answer: up. And “up” may be a s simple as “no more down,” meaning a stopped descent or a slight climb to exit the effects. In any case, if you’re below 1,000 feet you’re no longer “stable” per the mandatory requirements. If you’re above 1,000 feet, you’ve just been cued that the mileage interval, given the meteorological conditions, nonetheless has left you vulnerable to the adverse effects of wake turbulence–and you’re not going to proceed.

Which means, in the immortal words of my old friend the Chief Pilot at my airline addressing my 1991 class of Captain’s “Charm School” (officially, “Captain’s Duties & Responsibilities”) as we sat rapt: you’re going to “get the hell out of town.” Amen.

Back in the cabin? Expect the usual complaints about the delay for the second approach, plus a regular dose of exaggerated “there I was” tales about their wake turbulence encounter. So, don’t tell them–if you’ve done your avoidance and even escape properly, they’ll never know you even had a problem, which is the ultimate goal anyway: detecting and avoiding the problem in the first place.

The end result is, what they don’t know won’t hurt them, because you won’t let it. And that’s kind of why you get the privilege of flying the jet in the first place, isn’t it?

Winter Flying: Faith and Defiance.

I can’t decide if winter flying is is one long act of defiance, or shorter acts of combined faith. On a cold January day with an icy, raggedy ceiling and needle-like freezing rain rasping against the fuselage on taxi-out, on board it’s a steady 75 degrees. People aboard reflect the destination, not our departure point–and act of faith on their part requiring an act of defiance on mine.

It’s actually a worthy challenge, bringing all of the details to a successful conclusion: flight planning, routing, de-icing, preflight, taxi-out and pre-take-off de-icing. There’s a puzzle to assemble, jagged pieces of holdover times for de-icing fluid, precip rates and types–you know what’s reported, but you deal with what’s actually happening–and it’s up to you to account for the difference. Take-off performance degrades; weight limits based on the restrictions of leaving, but with due diligence to the weather conditions 1,200 miles south.

Boeing has given us a marvelous machine that will wake up encased in ice, but in a matter of minutes will operate from the ice box to the tropics. Not magic–just a lot of grunt work by a lot of people.

It’s a lot slower, but more than the temperature is involved: there are more requirements, plus people and machines work slower in the cold. As they should be expected to do, but which often results in frustration for those whose involvement is limited to riding the jet rather than trying to fly it safely. Sorry.

But eventually, we get to this:

Again, that’s going to be slow, too, by necessity. But be patient: the destination must be worth the trip, right? But inevitably, the factors a passenger plans to escape by air don’t make that escape easy.

Half the battle is getting into the air–where the other half is usually just as challenging. Again, the same crud that you want to escape packs a punch from the surface to the stratosphere. We’ll deal with that, too, at 300 knots, or maybe 280 if it’s bumpy. Already told the cabin crew to remain seated till I call them, when I’m sure we’re in safe, stable air. More griping from passengers, I know, but they’re not responsible for not putting a crewmember through a ceiling panel.

This is how it might look if anyone checked ahead (I did) so it wasn’t surprising face to face, really. Which looks more like this, and nobody’s getting to paradise till they work their way through this frontal line.

Eventually, we win: the further south we go, the more miles we put behind us, the weather–and the escape–become reality. You begin to get a glimpse of paradise with your 320 mile digital vision. The 20-20 eyeballs show the passage from land to water, a sure sign of warmer days for 160 souls on board, patient or not.

Soon it’s all blue, with ghostly outlines below that carve the indigo into brown and green, lush islands poking above the mild, warm seas.

Nassau, the Bahamas, straight ahead. Power back, begin the slow, gentle glide from seven miles high to sea level. More islands slide silently below the nose. Never tire of seeing the parade of blues, browns, greens; paradise.

Where’s the snow now? The icy grip of winter? Escape–by the lucky hundred and sixty aboard, each with their own getaway plan, winter runaways we eagerly aid and abet: someone has to break free, to teach winter a lesson.

A world away, if only but the blink of an eye in a lifetime, it’s nonetheless an eyeful. I’m happy for those who’ll stay, at least for a while.

Welcome to Nassau. For me, it’s a few moments of sunshine and sea air on the ramp while ground crews unload cargo, reload, refuel and get us turned around and ready for launch back to the north. Too soon, in a way, but not soon enough in another: this isn’t my escape–it’s my job.  From which, for the vagabond pilot, home is the escape. Will be back here, back and forth, all winter.

He’s headed home, too, a longer way back, but with a couple hundred aboard not facing the cold quite yet. But likely missing the scenery shrinking below as we climb and arc away to the north.

So long to paradise, hello radar scan; fuel burn, overwater navigation, peaceful cruise until you face the enemy line you already slipped through once today. Still there, waiting. The sun gives up, slips into the muck and so do you, both promising another trip around the globe another day.

There’s the final act of defiance, or maybe faith: through the choppy, sleet-streaked darkness, at 200 knots, toward the runway you better know is below the 200 foot ceiling.

Then it’s all about home, after appeasing the winter gods (“We brought at least as many back from paradise–you can ruin the rest of their season, plus make them wistful for the tropics the rest of the year!”) yet again. A healthy respect goes both ways; careful defiance, faithful flight. Starts again tomorrow.

Holiday Air Travel Tips 2012

This year we’re going to do the holiday air travel tips different, for one good reason: leisure fliers never do what airline industry insiders recommend. Don’t know why; maybe travelers already know everything, maybe they don’t care—maybe they just don’t like to be told what to do.

Regardless, since air travelers so often seem to do the exact opposite of whatever the airline industry recommends, here’s our new approach:

–Don’t prepare ahead of time. Nada—no collecting your travel info (flight numbers, departure times) in one handy place. Rather, have a bunch of papers with boarding passes, itineraries, receipts and even hand-scrawled notes, cram them into your bag somewhere and pull them out, act confused and look for someone (and there are PLENTY of airport staffers ready help you!) to untangle the mess for you. Much easier than having your act together and your travel information at your fingertips!

–Bring your dog, and let the dog out of its kennel in the airport public areas! Everyone loves your dog, no one is allergic to your dog, and other dogs won’t react adversely to your taking “just a little break” out of the required carrier, on or off the plane, right? And do ignore whatever “business” it does on the floor because “It’s no big deal” and the airport has “people to handle that,” of course. So no one else in the airport could possibly worry about health hazards.

–Don’t pack sensibly. In fact, just bring everything that fits into your suitcase—never mind sorting out liquids or cosmetics; those will be sorted for you by the TSA. That’s what the screening is for, and the passengers in line behind you aren’t in a rush to get on their flights anyway.

–Do not put your name inside your luggage! If you do, once the flimsy luggage tag is torn off, the airline will know who owns the suitcase, rather than sending it on a Disney-worthy odyssey to the Land of Lost Toys. You want that, don’t you?

–Rely on the airlines for your basic caloric needs. Food has been plentiful on the airlines since about 1965, remember? So why shouldn’t you expect in the course of your 6 hours of travel that the airline will cater a meal for you? Don’t bring non-perishable snack for yourself and please, don’t bring water aboard the plane. Some nutty people actually have reusable water containers that they fill up after security, then bring them on board to ensure their own hydration. Crazy, right?

–Dress like a bum or a heroin addict. That makes it seem natural to all the service personnel that you’ll encounter that you have high expectations, even with questionable taste and hygiene, and so they’ll be ready to work closely and cheerfully with you. Please wear your headphones, have your music jacked up so that when the Flight Attendants ask you if you’d like a beverage, you can say, “What?” for the thousandth time in their very long day.

–Once you board the aircraft, hog all of the overhead bin space near your seat. Realize when the flight attendants announce on the P.A., “Overhead bins are shared space—please place one small hand-carried article under the seat in front of you,” they don’t mean “you” as in you. Rather, it’s the “Smokey the Bear” type “you:” like only “you” can prevent forest fires,” which doesn’t mean you personally, right? That’s everyone but you—and they know it. Act like you don’t even hear the P.A. as other passengers struggle to get their items stowed.

–Once your flight reaches your destination and parks at the gate, as soon as the seatbelt sign is turned off, do not remain comfortably seated. Rather, immediately jump up and either stand uncomfortably hunched over because of the overhead bin, or crowd into the aisle even though the door isn’t even open and you’re not going anywhere anyway until all of the passengers in front of you have gathered their belongings and moved up the aisle. Why wait? Cram yourself into the aisle.

There, now you have the latest “do’s” and “don’ts” and it’s up to you to sort out one from the other. Hope this new way of passing the information registers in a useful way but regardless, when human nature takes over and the “me first” priority rules the day, at least you’ll have a tall tale about your awful trip to regale your friends with. Bon voyage!

Meditations From A Darkened Sky.

Day doesn’t give up the sky easily.

Last ditch, the blue fistfights with darkness like death: parts of the horizon arc fade differently, the sun exits dramatically or not; subtle or sudden, Ophelia or Faustus, depending on which way you’re flying and how high you are.

I mean east to west: bam, the sunset cattle-brands the horizon into an angry tight lip, then slams the sky shut like a granny purse, socking away the day for safekeeping, to snore under a fat pillow of layered cottony cirrus and leftover cloud piles, indifferent, floating; nothing to see here folks, so move along.

But eastbound? Not so fast: a jaundice swirls into the cloud bottoms, then fever fires the skyline like a malaria flush, the sun sighs itself westward, the horizon twists a blue frown–if you’re high enough, say forty-some-thousand–the downturn matches the curve of the earth, wingtip to wingtip. If you could hear it, dusk would be a groan; resignation, played out and spent, the day says “uncle;” hold that thought for tomorrow, finito.

Moonrise, maybe? Or not, depending on which rosary bead the month assigned to the comatose day, barely on life support and just waiting for last rites if the priest would ever get here. Yet, what is there to save? You pull the plug or you don’t, but the day flatlines regardless.

Like the cartoon before the main feature, the moon wants you to laugh, to goof around. “What the hell!” you say then wish you had the words back. Gotcha, again: joker luna burns her way through an undercast like an Alamagordo A-bomb. Or, just plain, unadorned, served up like tomorrow tossing a volleyball into today, shiny bone-white and perfect fine china, place setting for one but you’ll have to eat with your hands.  Any old way, any late day, the moon’s solid like the inner workings of a clock, underwriting tides and light in waves and wedges, depending on which blue you sail on.

And we sail on. Lights of passing ships, red on the right means a jet headed your way, emerald green and we’re fellow travellers. Sometimes moonlight makes their contrail glow like the luminescence of the deep sea and we’re just so many minnow streaking god-knows-where or why. Other times you only see the contrail when you cross it, then bump like a dumptruck when you do.

Opening act, the moonrise is: hey, where are you from? Seen it before; climb into the sky and race you till dawn, except celestial fine china never tires–but you do. You’re looking to the main event anyway: the Milky Way.

But tonight the Milky Way is part skim: atmospheric crud, even seven miles high, and you’ve got bad seats for the whole night show. What the hell, find your friends–Orion, never lets you down; Cassiopeia, vain beauty like you even looking at her, Ceres, you dog, and you, your jet flashing like a pimpmobile from below, insignificant from above. It’s a celestial tailgate, but you’re fake, manmade and only flying for now. But still.

Once it’s night, it’s just dark. Sure, we have the wubba, the blankie, the 14-satellite good to fifty feet GPS accuracy, and the guy in the left seat, keeper of the algorithms of gravity and lift and flight like the atomic clock that says when and how you fly and land. Because unlike the days sailing the night–you’re not really part of the heavens: visitor parking–and there’s a limit.

That’s okay. The non-stop must stop; it’s not “just flying,” which everything else in the sky does, but rather, “a flight.” And you, flyer for life, guy with the hands on the controls and the deliberately silent, taciturn “you’ll never get anything out of me” recalcitrance yet flying for all the years of your life, there is this. All of this; and you’re one lucky son of a bitch every time your feet leave the ground and the night sky lets you fly anyway.

When it’s all said and done, and you’re slipping through the terminal headed for home, and others wonder about your sly smile, you can’t help but think to yourself, how could I not?

But nobody would “get it,” really, so why say a word? Better just leave it at that.
