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.

Earlier this week, I was privileged to join the Airplane Geeks crew interviewing Igor Sikorsky III, grandson of the famous Russian aircraft designer. He gives new insight into this famous man and the early days of aviation. That, plus aviation news from around the world.
No de-rate allowed, so you get The Full Monty on both engines which is like super kick-in-the-pants giddyup on take-off, especially if you’re light.
And in a highspeed abort, especially if there’s a ground evacuation afterward–somebody’s going to get hurt.
That’s the original “fly the pieces” mentality, which I first heard from ol’ Jer so many years ago. And he’s right.
That it is. And I can’t even muster much disappointment when things go wrong, as they often will, not only expecting the worst, but also figuring the bigger pieces on fire will just burn off anyway. Look out below–we actually had a 727 years ago where one of the engines literally fell off.
Jerry gave a damn–and he was passing along the secret in the pilot world that also translates into life as well. That is, the question in a critical situation isn’t “what’s going to happen?” Well, you can ask that, but the real question you need to know that will determine what you do is “what’s the worst that can happen?”
I tried, really I did, to muster something other than strict adherence to standard responses the day Mexico City approach vectored us into a mountain at night in a thunderstorm. Really I did–but nothing, no panic, no fear; nada.


They have a different mindset than normal folks. Somehow, they’ve confused their pet with an actual meaningful sentient relationship and worse, they’ve confused their cat with a pet. It’s not like the cat or worse, cats, really give a damn, and yeah, they may look “cute” not giving a damn.
But somehow, maybe through the lack of actual interpersonal connections, maybe they’ve moved beyond a parenthood or a spouse-hood–or possibly both of those things moved on from them. Could be a bad experience with a scoutmaster or weird uncle–I don’t know.
That’s actually just a symptom, too, cat rancherhood, of a “damaged goods” brand that then explains the spillover of such arrested development into other areas. In the flying biz, we tend to be a little out of the mainstream. Our work interactions occur on the road with an ever-changing combination of crewmembers in varying locations around the country and the world.
In fact, they do better with the latter, sadly, than the former.
The cockpit door, when it’s open, covers the forward lav door. You can’t open one while the other is open. Unbeknownst to me–how would I know, actually?–one of our senior citizen flight attendants had chosen that moment to use the lav. And she fought to open the lav door just as I pushed my bag through the cockpit doorway, pinning my bag to the bulkhead.
“Let me out! Let me out!” She squeezed her portly self out through the narrow opening, haranguing me the whole time, adding, “You can tell the lav is occupied by the red sign there.” Duh. But if it’s behind the door, how the hell could I see that?

Strike one.
Really? Guess she didn’t have any interest in Mars. Or pets elevated to human stature, at least in certain peoples’ minds.
So when it comes up–and it will, eventually, on a crew–how someone’s pet has become a defacto “person” in someone’s world: be patient, relish the fact that it does seem weird to you, which is confirmation that you haven’t lost your marbles as they clearly have.



What if what if what if?
The first approach uses exactly as much fuel as we’d planned, but with predictable results: the ceiling is ragged; I catch glimpses of the approach lights but not sufficient to set up for a safe landing. And I won’t go below minimums, period.
Now the magic box “Progress–Fuel Predict” readout is a thousand pounds lower than before we’d started the approaches, even though we’d used exactly the amount we’d expected. But somewhere between our primary and alternate, we’d lost about twenty minutes of loiter time. Not devastating–we’d land at our alternate–right?
You can sum all that up in the great words of the modern day Sophocles: you fucked up–you trusted us. Never, never, never trust “what you know”–because that’s all a look backward. It may have been fine then, but we live and fly now, moving forward at hundreds of feet per second.
HEFOE check: Hydraulics, Electrics, Fuel, Oxygen, Engines–the ship’s just fine, all consumables at good levels, no systems problems. The radar picture shows the contour of the first approaching bands of squall lines, still twenty to thirty miles off shore. Winds are shifting between twenty and thirty knots, so we have enough slack to sneak in and out.
The Cabo ramp is a ghost town. You can feel something electric in the air–the steady wind off the ocean, strong, relentless, the breath of a giant storming ashore, the promise of a powerful lashing to come. The sky is a jaundiced yellow now, the sun shrinking and closing it’s eye into the western Pacific, not wanting to witness what night would drag ashore.
The kid asked, as kids will do, the question requiring a straight face and a kind answer: What’s “any mouse?”
Any mouse, indeed. Who isn’t? How funny is that really? Don’t think about it too long, but it’s not only who you are, but where you’re going–and who’s taking you there.

Well kinda sorta you–more quantitatively, as that cryptic bar code that lists stuff about (destination, bags, connections, weight, number) rather than the flesh-and-blood qualitatively you most appreciated there–or you wouldn’t be going, right? You won’t be just any mouse when you get there.
I love being any mouse, because while what I do is because of where you want to go, it’s most importantly, a large part of who I am. Let’s be any mouse then, shall we?
Sneak preview, yeah, we are. We have a lot of similar stuff front and back, don’t we? Not a lot of extra space either place.
Which is the reality of putting a bullet into the sky, you have to know, where weight and size are critical. Nobody has a lot of elbow room. Kind of bought the ride but not the space, you know? And you have screens in back to help you forget where we are and what we’re doing
while I have a bunch of them to keep me engaged in what you’re trying not to notice.
Silent partners, aren’t we? You divert, I engage. You ride, I fly. Together, we drag a knife across the sky and leave a puffy rumply scar that heals quickly nonetheless.
You can’t see that? Sideways ain’t always the best view. Are you even looking? No? Because you’re looking here:
A thousand degrees, fifty thousand pounds of thrust, let’s roll. Every minute, every vertical foot, every thousand miles one at a time, I’m on it–so you don’t have to be. Climb, climb, cruise, climb; lather, rinse, repeat. Route, reroute; guess-timate–call on your years of appraising the sky and what it might hold–outsmart it; the sky doesn’t care. But I do.
Rumpled sky having trouble getting settled into night. A thousand miles later, off the nose, the moon just punched the night sky in the face, rising bloody red at first but then that alabaster gleamy mottled ball that won’t shut up. No excuses for bad landings tonight.
I’ll take care of time and tide for you–fuel’s a’burning, I’m keeping count, ticking off the miles, sweeping 600 miles of sky ahead looking for trouble to avoid.
I’ll let you down easy, slow you down, deal with the thousands of foot-pounds of kinetic energy we owe now because we opened the double-cans of whupass on the runway hours back:
Ah, love those two, the way they bite the air and rocket us forward and up. But no worries downline, fellow mouse, I’ll land you there, wherever that is for you, and you can get off.
Getting there, flying–that’s my thing. Looking for me? Keep an eye out for any mouse, riding that gypsy wind. That’s not just what I do, it’s who I am.
I mean, sure, there’s plenty of drug violence. And yes, I did have to dodge through four lanes of traffic to evade a scroungy-looking cop trying to shake me down once, but he was either too lazy or too smart to chase me through the insane downtown traffic.
And yes, plenty of people with questionable intent in a city of 20 million, where you could simply disappear, kind of like the city itself is doing, slowly sinking into its own aquifer. And okay, maybe I did roll the dice in a sense, as an instructor-evaluator taking pilots down to Mexico City every month, showing them the safe way to fly in and out of the mountain bowl.
Well, it’s not even really this “thread-the-needle-through-mountains” approach and usually, through thunderstorm alley that was like playing craps weekly. And it’s not really that I minded the always slick (memo to Mexico City Airport: the rest of the world cleans the reverted rubber off of their runways every year or two, so get a clue) runway with the puddle in the middle that you hit doing about 150 and exit two thousand feet later at about 149.
More, actually, was requiring the qualifying pilot have a beverage and a Cuban at an outdoor cafe on the traffic circle outside the Presidente Hotel. The bar–Karishma–is where a whole crew got mugged one night. They noticed that suddenly the place was empty save the two airline crews enjoying tapas and the generously poured (“Tell me when to stop pouring, Senor”) refreshments there. Then suddenly, watches, rings, wallets–buh-BYE, as we like to say.
So to be on the “safe” side, we sat outside on the traffic circle–maybe more witnesses?–and since it was my idea, I made sure my back was to the building, so the new guy got to sit with his back to the insane traffic, puffing a Cuban (relaxing–but mandatory) and enjoying a refreshment, maybe getting a shoeshine from the roving vendors who’d magically appear, ignoring the demolition derby mere feet away.
And then on the side streets of The Polanco, maybe a quieter sidewalk cafe where I actually did much of my doctoral exam study: outside, books piled, good coffee, usually a thunderstorm in the afternoon that made me glad I wasn’t trying to fly a jet in or out at that moment. Out of nowhere, it seemed, in the afternoon towering big-shouldered thunderheads would roll through the mountain pass with raggedy sheets of torrential rain and thunder that echoed through canyons of concrete and steel, the reverberations so fitting to Tennyson’s “Ulysses” marching across the page before me toward the inexorable doom awaiting us all.
Harder to relax at dinner, though, when you were concentrating on the guard dog staring at your plate and whatever you were having for dinner. The armed guard restraining the dog had his eye on you and the plate alternately, and you had to wonder if either or both of them might figure that the dinner and your wallet might tip the scale in favor of mutiny. It was a stand-off in Mexico: the guard and dog making sure banditos didn’t mug you while you ate–but then the silently menacing pair themselves having to resist the hunger and temptation to rebid the transaction in more favorable terms.
And it’s not even the “one-eye-open” sleep in the airport high rise hotel with the un-level floors from the tipped buildings patiently waiting to tremble and topple in the next big quake they know is coming soon.
You wake up the next morning with the feeling of relief: ahh, The Big One they’ve been expecting didn’t happen while you slept, crushing you in tons of rubble that will take about ten years–if ever–to remove.

The fever lasted about a week. The shower nozzle effect (any chance of scheduling a colonoscopy? I’m prepped, just for the hell of it) lasted a couple weeks. Thanks cuz.
Couldn’t come at a worse time, when each cent spent on fuel strains the budget of every major airline. The fact is, a direct operating cost airlines cannot avoid is fuel usage, which is directly linked to the aircraft’s gross weight. Suddenly, there’s this:
That’s right: double-fudge brownie sundaes–in flight. Which brings us back to the jet’s take-off and climb gross weight. Seriously gross, in some cases.
Back in my Diesel-10 days, I flew with a giant of a captain who shall remain nameless but his initials are Big John. He must have tipped the scales close to three hundred pounds, and I admit, as a First Officer doing the flight control check, I’d purposely pull the yoke back far enough to jiggle his big gut (he’d say, “Whatcha tryin’ to do, boy, loop it?”) hanging over his lap belt.
Mystery solved on our first layover: the “galley wench” (that’s the flight attendant who served below decks in the DC-10 lower lobe galley) said he was downstairs with her, hoovering any uneaten food from passenger meals that were left over.
Maybe that comes from the grand tradition of fat sea captains who had to keep themselves well-marbled to survive months bobbing around on a hostile ocean. You never know when you’re going to have to spend two seasons and an eternity of reruns on an uncharted desert isle.
You never know just how long a three hour tour is going to be, right? We were doing a lot of trans-oceanic stuff in the ten, so maybe John was planning to be the only guy surviving in a life raft.
Regardless, Big John was just one of a growing number–literally growing–pilots who over the span of a career, drove up the fuel burn of the airline as his career dragged on.
First, there’s the big guns that announce themselves with a “ding” on the flight interphone: “Hey, we’ve got [insert uber-caloric dessert here] in back if you all want some.” Or, it just comes already on your crew meal. Either way, there’s this:
A dense chocolate cake-like pie. Sure, just eat a bite or two, right? You’ll run it off on the layover, right (in Toronto in January? YOU’RE LYING)? You missed lunch too, see, and this is okay therefore, mangia, right?.
Coming out of several Florida airline catering kitchens–it’s really decent Key Lime pie. Somebody actually recognized that Key Lime’s are just like any other limes–added for the citrus flavor for the pie, not the color–and it looks and tastes authentic. Probably about 800 calories, too.
It’s kind of densely creamy with just the right amount of tartness. And another 900 calories, probably. Sometimes the dessert just looks so innocent sitting there on your tray, small and innocuous, looking up, suggesting hey–eat me.
But word gets out when the inflight menu changes: hey–the cheese cake’s back. Burp. And sure, the salad’s always a sensible choice . . .
. . . as long as you don’t chase down it with another fat bomb:
I’m less vulnerable to the cake, which often is dry enough to suck all of the moisture out of your already parched (from the 2% cabin humidity) body.
That and the hermetically sealed bread item could absorb a fuel spill of considerable magnitude. So I find those non-confectionary things easy to avoid. But then there’s the catering out of Mexico:
Always some type of pastry dessert that face it–you’re going to try some of it. And when you do, you’re stuffing all 900 calories into your pie hole.
This is The World’s Most Dangerous Pastrami, slapped together lovingly (“Ey–we don’t got all day here, whaddya want?“) in the employee deli in La Garbage Airport, Flushing (is it just me or are these terms all appropriately suggestive?) New York.
But tofu’s healthy, right? Shut up:
Here’s the Blow Your Head Off spicy tofu, an O’Hare exclusive I can’t resist. The heartburn alone will keep you awake for at least a thousand miles, which is kind of the point.
You’re eating them. yes, you can defend yourself from any smells . . .
But you’re not gonna avoid cookies, are you? And never mind in flight, what about the junk you bump into hanging out before the flight? Like the old faves stationed around the nation, waiting:
It’s the best breakfast burrito in the nation, waiting for you at a little shop in the Albuquerque airport. Perfect salsa, will light your hair on fire. And in the Portland Airport, “Good Dog Bad Dog,” with sausages you are going to eat no matter what.
Need a closer look? There’s a video look at “Good Dog-Bad Dog” on the bottom of this page. Go there, try one–you’ll be hooked, too. And speaking of dogs, back to basics in the Oklahoma City Airport–Sonic, headquartered in OKC, offers you the essential foot-long chili-cheese-onion dog right across from the gate for your convenience:
Don’t get too smug, either, if you’re not a big butt pilot–we’re only two of 165 butts on my airplane. Yeah, we notice–
The suitcase will fit under the seat–but what about fitting in the seat? Anyway, that’s what’s driving up fuel costs, along with the constant mayhem in the middle east, hurricane rumors near the Gulf, a flu outbreak at a refinery in Jersey–whatever. Those are things Al Gore says we can’t control. Eating in flight is quite another thing.
But actually, it doesn’t look like Big Al’s skipping any meals either. So let’s just forget it–this is The Land of Plenty, to fly across it is going to take plenty of fuel because of all of the plentious butts on board.
Canada’s future is certainly bright, judging by the students in Miss Giulia’s sixth grade class at St. Monica Catholic School in Ottawa. What an articulate and considerate group they are, and they were gracious enough to share with me some questions about airline flying after studying the basics of flight earlier in the school year.
What do kids wonder about when it comes to flight? What did they discover in Miss Giulia’s classroom that sparked further questions about flight?
I asked–and they answered. Here’s a selection of their questions and my answers, with my heartfelt thanks to Miss Giulia and the entire class for generously sharing their time and ideas. In fact, they asked so many good questions that in order to answer them all, I’ll make “JetHead Goes to School” a series reappearing now and again with new questions and their answers.
That’s a good question. If you stay upwind of the storms, usually there’s no effect, although lightning has been known to reach ten miles from a cell to another cloud—or an aircraft. Hail, too, can blow out of the top and travel for miles. So it’s best to keep a healthy distance.
The rules are, we need to stay at least ten miles from any thunderstorm. Radar helps us do that, especially at night when the storms are difficult to see. Here’s a picture I took as we flew by a storm pretty close: 

Any contaminant ruins the smooth flow over the wing. In flight, the leading edge of the wing—that’s the forward edge—is heated internally with air ducted from the engines that is at about 500 degrees. No snow or ice can accumulate there. You probably never noticed, but we also have to check the jet engine intakes for snow and ice. Chunks of ice can break off and get sucked into the engine, damaging the components that are spinning at 30,000 RPM or more.
We usually de-ice near the take-off runway because the de-icing fluid loses its effectiveness over time. We have charts that are based on the type of precipitation falling at the time that shows us how long the de-ice fluid will protect the wings, so we make a good effort to be ready for take-off right away after de-icing.
As with any major endeavor, the pilot career field is difficult to get into and stay successful in year after year. There are constant checks and exams we have to pass, not to mention twice a year physical exams. But also like any major endeavor, anyone, male or female, can succeed if they set their mind to it and do the work required.
That’s all the space we have for this week, but check back regularly for more Q&A that will become an ongoing series, “JetHead Goes to School.” Again my sincere thanks to the children of St. Monica’s school and their most conscientious and caring teacher, Miss Giulia.

That’s here, middle of the night here, before you messed it up. Spartan. Antiseptic. Do not disturb. A trail of clothes from the door to the bed–worry about everything else tomorrow.
Sleep, and it’s that dream again: you can find the gate, find the plane, but there’s no door from the gate to the plane. Which is the way home, of course. No way home–just the waiting place, halls of marked time and any old place.
Good dog–you’re ready to swim in the deep blue. People will ask you questions, like “What’s it like to be a trained dog working in the blue every day?” Or maybe they’ll have something equally inane more for each other than for you, like “we’ll let him on” or “we need him” as you try to slip by them going to the office. Funny stuff, right? More likely, though, they have to go to the bathroom; they want to share that with you, assuming you have a constant awareness of toilets and locations, like you do with bailout airfields and low fuel contingencies in flight, right? Funny stuff.
Just get me to the gig. Snake through the masses herding across the wide-open plains, grazing, mooing; hoofbeats at a shuffle.
The ants go marching out again, hurrah. Step around, mind the Mickey head. Wind your way through; heft the bags, schlep the bags, onward to the gate. Show your ID: yeah, it’s Mickey. Let him on board.
She’s your big ol’ dance partner, every song, every leg, and just like you: all about the getting there–but not staying. Folks trundle off, more trundle on; makes no difference. We do our same dance steps, carefully and deliberately without art. Over and over–same old song. You know the words:
We say Mass for the Earth, the litany of escape–then we leave, but everyone still in their pews, seatbelts on and tray tables stowed. Then the aluminum conga line–every-buddy-CON-ga– to the runway. This:
In this:
Unpressed and rumpled–doesn’t matter; a little faded, all the better. That’s cruising, ain’t it? It’s like Saturday against your skin. That’s the jailbreak from the suitcase–off with the polyester, and Mickey’s head; jeans, amen.
