How to NOT land at the wrong airport.

As a pilot, you’ve landed at airports around the world at least a thousand times in many different aircraft, day and night. So, are you confident? Relaxed? Sure?

Hell no, and with good reason: there’s just too much at stake. Passenger safety, professionalism, your career.

So you’ve spent that career–over three decades, and counting–as a professional pilot, trying diligently to NOT land at the wrong airport.

Here’s how.

It starts a thousand miles prior to landing, and it’s a mundane yet essential procedure. In the chocks, preflight, do it: you read the navigation waypoints from the screen displaying the route of flight in the jet’s navigation systems (there are two, backing each other up) out loud, while the First Officer reads both the paper flight plan and the Air Traffic Control system printout (you read it silently as a triple back up). They must match.

The last waypoint entry MUST at least be a runway at your destination, preferably an approach, too, but at the very least, a landing runway. This will be essential later.

Everything must match (ATC clearance, nav system route of flight) and so must the enroute distance in order for the fuel calculations to be valid. So once again, you MUST have an accurate final fix, preferably a runway.

Even at this preflight step, there are mundane challenges: tired? Long day? We’ve done this a zillion times before, in fact just last night? We’ll put in the final waypoints later, because we’re not sure which runway they’ll be landing on?

Don’t give in. Do every nitnoid step, every time. Route, mileage, verified. Period.

The same human factors challenges recur at the top of descent: almost done, tired, end of the work day, we’ve done this often.

Fight it! Verify the landing runway, and be sure it’s correct, complete, and active in the nav system.

On approach, be wary of the siren song from Air Traffic Control, especially at night: “Do you have the airport in sight?”

If you say yes, you’d better be 100% sure, but even then–the best answer is no.

Why? Because if you acknowledge visual contact with the runway, the next clearance you’ll get is “Cleared visual,” meaning radar service terminated–fly to and land on the designated runway.

Why? I mean, why accept that clearance rather than maintain radar tracking of your position and altitude from the ground controllers monitoring you and, as importantly, the other air traffic around you?

Can you really identify and verify other aircraft and ensure separation–at night? Why would you?

Just last night, landing at DFW, something I’ve done a thousand times, we refused the visual clearance.

Why?

Because a thin and broken under cast obscured at least half of the ground references we’re dependent upon to confirm our position–and that’s at an airport I’ve flown into since the eighties, much less some small, out-of-the-way airport I seldom see. Regardless, there’s no point in speculating or trying to visually orient ourselves with half of the usual landmarks obscured, especially at night.

Plus, why not give our passengers the benefit of Air Traffic Control radar keeping us clear of other aircraft?

Finally, having done due diligence a thousand miles back, we know the distance remaining (there’s a mileage countdown displayed in six places in the cockpit, including in my heads up display–if we’ve put the landing runway into the system) so that if we only accept the clearance after we’re vectored onto a final approach segment, we’ll know exactly how many miles to go before touch down–if we constantly check it.

Using the three to one ratio of a landing glideslope, we know that at 1,000 feet, we’d better be no farther than 3.3 miles from touchdown.

If the “distance remaining” indicates significantly more–you’re at the wrong airport.

If you’re under radar control, that won’t happen. If you’re on a published and verified segment of the instrument approach, that won’t happen. If you’re monitoring the distance remaining to the valid touchdown point, that won’t happen.

Tired happens. Get-home-itis happens. Routine happens. But god forbid the perfect storm of those human factors, plus poor visibility, unfamiliar terrain, and a failed procedural navigation process (the mundane stuff cited above) all comes together.

As with so many things in aviation, it’s not necessarily the big, spectacular failures that bite you in the ass. Rather, it’s the simple, tiresome, mundane everyday stuff that must be attended to–or, the results can be headline news, and not in a good way.

The Annual Pilot Beating

awful house

Awful House, 4:30 am.

Try to decide which is worse–the two roaches scurrying around the condiments, or the lame-brained guy in the paper hat, prattling on about his guts while you try to eat.

“You ever get that real sharp gut pain,” he asks, “where all of a sudden you really have to go to the bathroom super bad?”

Must be cancer, I want to say but don’t. You should get it checked out.

What I really don’t want to do is chat here at the buttcrack of dawn while I’m trying to cram one last run-through of the memory items I’ll be expected to recite for the oral exam prior to the simulator exam: “Passenger switches–on.”

What the hell is a “passenger switch?” Actually, that should read “fasten belts switch,” because that’s what you need in a rapid depressurization. Boeing obviously misprinted the step, but since Boeing published the procedure, if you don’t recite it their wrong way–it’s wrong.

awful 2

And there are pages and pages of numbers, stats, limits, operating procedures and legalities, all fair game for the oral exam. Experience proves that the best defense is a good offense:

Question: what’s the crosswind limit for a Category 3 approach?
Answer: 15, but that may be further reduced by the runway condition to 10 if the RCR is less than good, which brings the requirement for an Autobrakes setting of 3 or MAX.

Answer more questions before he can ask them.

And pay with cash here: the guy at the register is either an ex-con or a heroin addict; the neck tattoos and shaved head could go with either.

The 05:30 “Stump the Dummy” (me) session goes as planned: two hours that are part instruction, passing along new or revised procedures, as well as asking questions–and me over-answering as a defense. That worked, because now we’re on to the simulator check. Today we have one of the new, most advanced “boxes,” with all-electric motors (no hydraulic carnival ride) and the most advanced digital visual with Google Earth displays.

And for me, a windfall: there was no line first officer scheduled for my sim–so I get a “seat filler.” That means an instructor, and today it’s Bev. She knows the aircraft systems and procedures inside and out–because she teaches them every day.

IMG_1172

This first part, planned for around two hours, is termed by the FAA a “jeopardy event.” That is, if you don’t handle everything correctly, you lose your flight qualification. No pressure–just your ability to make a living at stake.

We start with a low-visibility take-off: fog and a visibility of 500 meters. Brief all the usual stuff, plus the extras: Localizer frequency tuned and identified, specified usable within the threshold, HUD set NP with correct runway length, runway heading set. Of course, a question before takeoff:

Evaluator: what’s the limit for the take-off alternate?

Me: 330 miles or the lowest minimum at the departure field for a single-engine return, which is 300 feet, and the present viz is 500.

Over answer–good defense.

Once “aloft,” we return to set up for a Category 3 landing, which is through weather to the lowest limit of my qualification, which is 50′ and a visibility 300 feet.

“Take the airplane,” I tell Bev, “I have to make the new FAA-ordered PA about electronic devices.”

pa

“Good job,” says the evaluator. Maybe he thought I’d forget–the change only came out this week–but I didn’t. We hit all of the marks to set up the approach, then fly it carefully to a landing under an indefinite ceiling and 1/8 mile of visibility.

IMG_2391

Then, through the magic of flight simulators, the computer slingshots us back out on final to fly the approach again, this time to a low-altitude missed approach. That’s a two-part test: you have to prove that you can do the maneuver, no easy task at 50′ and marginal visibility, and you have to prove that you can discern when to go-around and when to land.

Hand-flying the approach, near the ground, at 50 feet: nada. I punch the go-around power toggle on the throttles and we pitch up aggressively, away from the runway.

“Flaps 15 . . . positive rate (means we’re climbing) gear up.”

We’re climbing like a scalded cat, I’m watching the speed increase so I can safely call for configuration changes and NOT overspeed the flaps as we rocket skyward.

cockpit night

All is well through flaps fifteen, flaps five, flaps two; Bev, ever the excellent First Officer, warns me: Houston, we have a problem.

A glance above my head to the flaps display panel shows a trailing edge flap segment stuck extended. The jet wants to roll, I won’t let it.

In Cat 3 conditions, especially below 100 agl, a go-around can mean ground touchdown regardless, so naturally it’s done with full TOGA power and pitch.

That compresses the procedure, and split flaps disrupts the cleanup, yet the power (and thus over speed and altitude bust potential) remains high. Throw in the fact that by design, all 737-800 go-arounds are hand flown, and the missed approach was deliberately chosen because it has a 2-step level off, first at 3,000, then a turn and a climb to 4,000.

app

Will you remember the 3,000′ hold down, especially at max power, with cleanup disrupted?

Again, you slow down and prioritize: I’m thinking level off and speed control. We’re forced out of our normal litany for cleanup, but we’ll claim the time and space we need–not rushing–to accomplish everything. I tell Bev “Declare an emergency, tell tower we’re going straight ahead at 4,000.” Why fight the 3,000′ level off? She concurs.

Then we have to set up an RNAV LOC which must be flown with LNAV VNAV, but you have to recognize that VNAV doesn’t sense a flaps 2 landing and will put you below the 168 KIAS Vref for flaps 2.

Also, with  a runway visual range less than 4,000 feet, the runway is technically wet (better not miss that) and landing distance with a 168 KIAS Vref will be critical.

Which leads to the ATC controller trying to induce us to take a pattern turn to crosswind, I refuse because we have too many checklists to do. That leads to the instructions to hold present position, left turns, which I could also refuse, but I do know that’s a test too: can you set up holding on the fly? And will you remember that “present position hold” sets up right hand turns, which must be changed or you end up in the wrong airspace.

In holding, Bev and I work through all abnormal flaps and emergency landing checklists; I go to school on the adverse roll moment the autopilot is obviously fighting to be ready for the hand flown final, recall from experience that a flaps 2 landing will be at high speed and power must go to idle uncomfortably early or you will float and the wet landing distance will eat you alive.

And don’t forget to modify the standard LNAV-VNAV procedure with “speed intervene;” some might try flying it with autothrottles off, but that’s flirting with the Asiana screwup in San Francisco, with the added challenge of marginal weather with an abnormal configuration. Think that might be distracting?

Throttles idle over the fence, decent touchdown, reverse and ABS. Bev counts down the airspeed as we roll out. Final question: “Would you taxi clear?”

Me: “No. The runway’s already closed for the emergency.” And it will need to be checked by the airport managers before reopening anyway.

Check Airman: “Well done, jeopardy part is complete. Take ten minutes, I’ll set up for the second half.”

Done. The next two hours will be advanced training: stalls, engine failures, tailwinds into short fields, engine failures with high flap settings on short runways, double engine failures; all just good training. The Check Airman is one of the best and I lucked out getting him for an evaluator and Bev as a seat filler.

And when the advanced training is complete, back to the real world and the real jet. Good for another nine months or ten thousand miles–whichever comes last. I think a cup of coffee is in order, maybe something to eat–I will find both, my better judgment dictates, anywhere but the Awful House.

A certain darkness on the flight deck.

BA 747

Nothing wears a pilot out like watching the other guy fight the jet. And nothing degrades flight performance like the inevitable outcome–the jet wins, as it should.

This pointless tail chase arises out of two competing malignancies. First, there seems to be an inborn reluctance to consign more and more vertical and lateral (read: climbs, descents, and navigation) maneuvering to flight management systems. Part of that, I believe, comes not only from a reluctance to acquiesce to the reality that in most cases, the automation can do a better job than the humans, but in a real sense, from a backlash against the encroaching automation subsuming what used to be mostly art.

fms crz

Hogwash, in both cases. Because not only has such resistance to the encroachment of technology been going on since the Wright Flyer gave way to the Curtis Jenny, (when we first started getting CRT flight directors rather than the old mechanical gages, the crusty old guys swore they “didn’t work worth a damn” and distorted their vision), there’s also the incontrovertible fact that technology has made the airline industry the safest it’s ever been.

Ground Proximity Warning, Windshear Detection, terrain and weather escape–all possible because of the integrated software and hardware now part of the wraparound design technology inherent in the new jets.

lufthansa 747

The second, darker factor in the resistance playing out on flight decks worldwide is more insidious, but no less troublesome. That is, an undercurrent of frustration and dissatisfaction, most that has little or nothing to do with the technology that becomes the focus of the bad ideas. Specifically, there’s a generation of professional pilots who have seen their retirement wiped out, pay slashed, career stagnated, base (and thus domicile) closed, job moved or in thousands of cases, eliminated; families torn apart, a suicide rate grown to 4 times the national average, and promotions eliminated, reversed or in so many cases, downgraded.

When those factors are the undercurrent of the profession, they don’t simply vanish when the gear retracts.

AIPTEK

The end result, the “kick the dog” outlet–knowingly or not, often becomes an opposition to standard operating procedures. Not necessarily blatant, but distinct: “These autothrottles don’t work worth a damn!” (Yes they do–and more smoothly and efficiently than you) or “This descent profile is bullsh!t” (No it’s not–and it would have saved the thousand pounds of fuel you wasted descending and flying level fifteen miles early).

This seems consistently evident in the case of pilots busted back from captain due to job cuts, or pilots forced from larger to smaller aircraft for the same reason: they hate–and fault find endlessly–in their “diminished” circumstances.

Which leaves a crew flying a complex jet with a few “I know better” techniques born of resistance to the new, nostalgia for the old, and a self-righteous need to pay back some of the huge bloodletting in an increasingly anemic career field.

Any step outside the normal operational profile throws a two-headed onus on the other guy. First, there’s the WTF paralysis as you try to figure out what the “new” technique is. Second, there’s the very complicated and moving target that is return to the normal profile–either from the computer’s design or more rudimentary airmanship. Are we getting there? How, when or even, if?

DSCF3175

All the while, there hangs in the air the unasked, unanswered but certainly prescient question: when push comes to shove, will professionalism necessarily trump resentment?

So far, the industry-wide results speak for themselves–yet hardly create any assurance that they will continue to do so. I’m fortunate to fly in a Flight Department where Standard Operating Procedures rule the operation, period. And they always will, in my cockpit.

But with constant downward pressure on pilot pay, airline profitability, flight manning, and ultimately, the profession under siege, the unasked question may eventually provide its own answer, and my guess is, it ain’t gonna be pretty.

orion

The Orion Nebula contains a very young open cluster, known as the Trapezium due to the asterism of its primary four stars. Two of these can be resolved into their component binary systems on nights with good seeing, giving a total of six stars.

The basic framework for the moving target that is flight comprises an architecture of anchors and change: weights dictate speeds which prescribe duration and altitude. The wooden stake in the ground, sure as the tenuous GPS alignment reluctantly tolerating the gusty wind bucking the 40 foot tall rudder assembly, will be ancient history as soon as we move. But to know where we’re going, we have to know where we started from.

The stars of the Trapezium, along with many other stars, are still in their early years. The Trapezium may be a component of the much larger Orion Nebula Cluster, an association of about 2,000 stars within a diameter of 20 light years. Two million years ago this cluster may have been the home of the runaway stars AE Aurigae, 53 Arietis, and Mu Columbae, which are currently moving away from the nebula at velocities greater than 100 km/s.

737 night

And drawn as moths to the flame, pairs and singles, Noah’s children march aboard, halfway to somewhere, their presence now a light reflected forward, as meaningless in the here-and-now as the two-by-two was in the pouring rain, boarding the ark: it’s all about the retelling later.

A nebula is an interstellar cloud in outer space that is made up of dust, hydrogen and helium gas, and plasma. It is formed when portions of the interstellar medium collapse and clump together due to the gravitational attraction of the particles that comprise them. The gravitational forces between particles is directly proportional to the their masses, remember?

“Now” is a moving target, mortgaged by “then,” which in the preflight cockpit is more about “there:” the air nautical miles divided by pounds of fuel burned per each. The symphony of electrons conjures an opus of transformation: if everyone plays his part, there will be a smooth harmony of fire, speed and distance, underscored by dollars transferred and spent, buoying steel and fuel, blood and bone, suspended across the night sky like the fiery tail of a comet from here to there.

When a star burns through the last of its fuel, it may find itself collapsing. For smaller stars, up to about three times the sun’s mass, the new core will be a neutron star or a white dwarf. But when a larger star collapses, it continues to fall in on itself to create a stellar black hole.

It’s always the “after” from which meaning is made. For the ark, that’s arrival. For the pilots, that’s enroute, the record inscribed across the night sky, 500 degree exhaust gas boiling away at -55 C ice crystaline air, backlit by the moonlight as a spider web across the star-flung dome. Keep the fires burning.

Black holes formed by the collapse of individual stars are (relatively) small, but incredibly dense. Such an object packs three times or more the mass of the sun into a city-sized range. This leads to a crazy amount of gravitational force pulling on objects around it. Black holes consume the dust and gas from the galaxy around them, growing in size.

And for those left behind, like those yet ahead, the unseen passage is one of either anticipation or regret, of bidding welcome or goodbye, of time spent or lost. You can’t not feel the diminishing weight of both, lighter the farther and higher you go. No hands hold you, just wings and lift, time and tide, fire and ice in balance. Passage.

Orion’s light is either a promise given or a wish fulfilled, depending on where you see it and when. At light speed, the trapezoid assigned to the mythology, the murky nebulae burning within, left home in the time of Alexander the Great, overtaking you at 41,000 feet a couple millennium later. Either way it’s a lie–a now from then, seen light years away; then as if now.

al great

Just like your flight: you’ve crammed a million footsteps into the counting of minutes rather than lifetimes, footless, seven miles high, an ark sailing on a rolling tide of time and place, borne of fire, trust, hope, and light.

For those in the back, the metal ark is but conveyance. For you, more an arc inscribed across the night, more than passage but less than permanence. Like the silent, obedient constellation, the gas blue light won’t matter until it’s examined in retrospect. You live in the passage, grant the flight its own universal time and space, its million shards of where and when and ultimately, why. But it’s never about “there,” for you. Only leaving there, and flight across darkness: night, the shadow of life, then home, the nexus oF light.

How do YOU land at San Francisco International Airport?

Posted in air travel, airline, airline pilot, airline pilot blog, airliner, airport, flight crew, jet flight with tags , , , , on July 9, 2013 by Chris Manno

sfo 2

Here’s how you land at San Francisco International. First, the view over your left shoulder as you cruise “downwind” for your arrival into San Francisco International. You’ve arrived from the Pacific side of the airport, so you can plan (they’ve probably advised you already) on landing on runway 28L, which is the runway you’re paralleling on downwind. Yes, there are 2 runways that you are paralleling, but the logical one for you is the one on the left. Here’s what the airport diagram looks like, with an arrow pointing to 28 Left:

sfo 10-9a

Let’s talk about all of the runways at San Francisco International (SFO), because their are simultaneous operations on all four runways, so your landing runway is not operating independently or simply–nor are you as a pilot landing at SFO. Those two runways intersecting your landing runway will be launching aircraft out of SFO even as you are landing: yes, they’re crossing your runway–and you theirs–simultaneously. That means the SFO tower controllers are managing a complex ballet of speeds, timing and clearances. They’re doing a precise, excellent job, but a lot will depend on you: you must fly the assigned airspeed exactly in order for all of the moving parts in this synchronic mix of flying metal to mesh smoothly.

sfo 1a

But wait, there’s more: runways 28 left and Right are too close together. Built built on a man-made pier, the pair are crammed closely together, closer than the standard, required spacing for parallel runways. Why does that matter? Well, because on final, aircraft approaching the runways at the same time will fly closer than the normal lateral separation required by the FAA standard:

28 parallel

Not taken with a telephoto lens. Rather, that’s a jet landing on 28L, taken from the cabin of one landing on 28R.  Lateral separation is minimal–by virtue of a waiver of the standard separation that the FAA granted to SFO–so there are more restrictions on you, the pilot. First, you must not overtake the other aircraft. That’s because the trailing aircraft is charged with maintaining visual separation, because the leading aircraft can’t really see the trailing aircraft. If you overtake him, there will be a period where neither can maintain separation visually. So airspeed control must be exact, usually assigned by tower–to ensure separation from another part of the moving mechanism: aircraft are taking off on the intersecting runways, shooting the gap between your landing aircraft (and the parallel partner above) and the ones who landed before you.

Here’s the instrument approach for your landing runway–and there’s a complication today with that, too.

28L ILS

Today, the radio glidepath, or “Glideslope” (GS) is NOTAMed (NOTice to AirMen) out–meaning you will not have that descent guidance available on your display, so, you’ll be expected then to manually crosscheck the “step down” altitudes (7000, 6000, 5000, 4000, 3100, 1800, and 213) against the distance marked on this chart. All while flying the specified speed assigned by tower, which you must integrate with the maximum speeds allowed by the flap configuration required for the approach and landing.

bug eye cockpit

Sounding too complicated to manage? Well, it’s not. In fact, it’s routine: very often, you’ll encounter intersecting runway operations (Chicago O’Hare comes to mind, and those controllers do a fantastic job of choreographing that ballet); many airports have reduced, FAA-waived runway separation (hello, Minneapolis), and at any given time, airports around the nation report various instrument landing system components temporarily out of service .

The glideslope being out wasn’t a surprise, either: you were advised by NOTAM (see above) before you even took off on this leg of the condition of the equipment and on your approach briefing (probably done within the last hour) you reviewed the requirements, procedures and complication with the other pilot(s) in the cockpit prior to starting the approach.  And if you’re savvy,  just in case, you briefed the approach to the parallel runway as well. That’s because at any point, due to traffic load or other factors, SFO tower can swap you to the other runway–just like that but again, that’s routine in the airline biz. Expect it, pre-brief it, deal with it.

fms crz

Which means reprogramming the correct approach points in the Flight Management System (FMS) on the fly (pun intended) and verify each point, then set up the correct intercept to a forward waypoint in the FMS. All the while, don’t forget our friend out there–it’s your responsibility to stay clear–

28 parallel

Fly the speed assigned to the waypoint assigned, maintain the altitude minimums according to the above chart by comparison with your distance from the field and . . . configure for landing, while observing the flap speed limitations of your jet.

Here’s where you get to do your own balancing act within the swirling gearbox of approaches, landings, takeoffs and climbouts: if tower assigns you to fly a speed of 200 to “DUYET,” (see approach diagram above), that means you are limited to flaps 15 (have to be below 190 for more). But DUYET is at 1,800 feet and your airline has a “stabilized approach” policy below 1,000 feet: must be in final landing configuration and stabilized airspeed (neither increasing or decreasing) with a stable power setting (neither spooling up or down) from 1,000 feet to touchdown.

Power control is key to airspeed.

Power control is key to airspeed.

From 1,800 at DUYET to 1,000 feet, at a standard descent rate of around 800-900 feet per minute, you’ll have about 60 seconds, maybe less depending on tailwinds, to decelerate about 50 knots, then re-stablize the speed and power, and extend the flaps from 15 to 25 to 30 or 40 for landing. If not, mandatory go-around–meaning, initiate a climb following the “Missed Approach” instructions on the chart above. That’s also included in your approach briefing, remember which one–left or right–that you’re doing because remember, there are aircraft launching as well, mixing into the airspace. Then either repeat the approach (also very routine) or divert.

Stabilized? Good–now the only thing YOU must do is monitor descent rate, speed and alignment. That’s why a stabilized approach is vital: being set in descent rate and airspeed and power setting frees you to simply fly to a safe landing. After an approach that you now know is anything but simple. Happy landings.

Motion Lotion: What’s the Commotion?

“The only time you can have too much fuel is when you’re on fire.” –Anonymous Pilot

Those are words to live by, in the flying business–but jet fuel is expensive. In fact, it’s just about the largest expense in the operation of the airline, which is why it makes sense to use fuel as sparingly but sensibly as possible. But as a passenger, what’s it to you?

Well, for starters, this:

tstm day

Do we go around it? Above it? Through? You won’t like the last option, but fuel is the double-edged sword in this fight: more means we’re heavier, which limits our climb. Plus, going around the weather will burn more fuel, limiting our options at our destination:

fms crz

We’re at 36,000 feet now, which is just about the optimum altitude. “Optimum” is a moving target: as you burn off fuel enroute, the jet gets lighter and the wing can handle a higher altitude, which means the engines can operate at a lower thrust setting, thus saving fuel. We’re within 200 feet of the max if we climb to 38,000 feet to top the weather. We can wait till the “max” readout shows “380,” or really, from experience, we know that in the time it takes to request and receive the clearance, plus what we’ll burn in the climb, we’ll be at the correct weight. But, there’s always a catch.

410

The airspeed tape on the left shows us a very narrow operating range at the top end of our altitude capability. That is, your range of acceptable airspeed is from about 212 to about 245. The “chain” above that shows the area of high speed buffet, meaning parts of the aircraft, above that speed, will begin to go supersonic. More importantly, though, in my mind, is Mach tuck: swept-wing jets tend toward a pitch down near the high speed limit, and guess what a pitch down does: your high speed becomes even higher. In a jet, particularly a passenger jet, if you don’t recover aggressively and immediately, you will not be able to stop what will become a dive.

On the bottom of the tape is the yellow line we call “the hook,” which is the slow speed stall. If you go below that speed, your airfoil will stall, and you will fall.

PFD coffin corner

So, at 38,000 feet, we have very little margin between the high and low speed buffet, requiring extreme vigilance on our part: turbulence, mountain wave action, or a drastic updraft of any kind can push us beyond either speed limit. Which is also part of the balancing act the captain must perform:

pfd coffin corner 2

I insert a slower Mach number in order to cruise more toward the middle of the range between the high and low speed limits. That, too, though, will affect our arrival time, won’t it? But that’s a balance I feel can be maintained, knowing that we’ve picked up some direct routing already. I’d rather sacrifice some time (and really, fuel) to gain a better pad between any adverse effects (mountain wave, thunderstorm up drafts, windshear, clear air turbulence) that could push us into either boundary.

And, I’ve already checked: the winds at the higher altitude are more favorable. To be even more accurate, I’ve requested a data-linked update to our flight management system, updating the projected winds the computer is using to calculate the times, distances and fuel burn it displays because what we data-linked into the system on preflight hours ago may not still be accurate:

fms crz wind update

The photo makes it hard to see, but the new, uplinked wind speeds are highlighted, all I need to do is push the “EXC” (execute) button and the entire nav calculation will be updated in a matter of seconds.

Climbing early has taken us out of more headwind earlier, so I believe the ETA will be largely unaffected. This hunch is borne out as we progress in our flight:

flt prog 1

We cross Pocatello, Idaho (PIH) six minutes ahead of schedule and up 700 pounds on fuel. If, however, the higher altitude winds were less favorable, we’d end up with the same result by going around the weather (more miles at regular cruise Mach)  as by climbing above the weather (less miles at a slower speed). The latter option is better, fuel-wise, as you can see from the fuel log above. But we’ll do whatever is safest and most optimum first, and worry about timing  later. Plus, if we don’t have what I consider a comfortable high speed-low speed margin at the higher altitude–we’re not climbing, we’ll just have to fly the additional miles (and minutes) around the storm.

It’s not just air miles between us and Seattle–it’s a constant balancing act of time, fuel, altitude and route. It all goes on steadily, quietly but relentlessly in the cockpit, but we all share the payoff in the end.

Summer Weather, Flight Delays and YOU.

fll sunsetYou 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:

wx radar 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:

lowgn4All 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.

wx radar arrivalSee 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?

Tales From The Flight Deck

Posted in airline, airline industry, flight, flight attendant, flight crew with tags , , , , , , , , , , , , on April 23, 2013 by Chris Manno

dc10 frontBack 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 . . .

connieBut 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.

aeroflotAeroflot 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.

kgbInstead, 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?

Posted in airline, airline delays, airline industry, airline pilot, airline pilot blog, airline pilot podcast, airline podcast, airport with tags , , , , , , , , , on April 13, 2013 by Chris Manno

cockpit panoThe 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.

left seat

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?”

freefall

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.

38Other 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.

casket 1

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 . . .

old-young

. . . 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.

Pilot Report: 737-Next Gen Heads Up Display.

Posted in air travel, airline, airline pilot, airline pilot blog, airliner with tags , , , , , , , , , , , , , , on March 5, 2013 by Chris Manno

hud aaFirst Officers love to derisively grumble about the captain being a HUD cripple–meaning he can’t make a decent landing without the “HUD”–Heads Up Display.” Fine–count me in: I swear by the device.

HUDs are standard now on the Boeing 787 and I’ll bet there’s less grumbling from F/O’s for one good reason: now there’s a HUD on their side as well in the 787. On the 737-800, the HUD is only on the captain’s side.

I’ll admit that I had my doubts too when I first started the transition from MD-80 captain to 737 captain. How could Flight Management computers, ILS antennas GPS and symbol generators reliably synthesize a runway display before my eyes despite clouds and weather obscuration? Worse, without any ground-based approach aids, how could the jet’s computers and satellite receivers pinpoint our position close enough to allow for safe descent and approach–completely in the blind?

I’ll also admit, like everyone else learning to use the HUD, I was swimming in symbology and information at first. Add to that the transition from traditional round dial displays on the MD-80 to the more advanced flat-panel displays on the Boeing Next Gen jets and you have a real spaghetti bowl of information swirling in front of you and in the case of the HUD, it’s all in ghostly monochromatic green, compared to the color-sorted original display on the instrument panel that is reproduced in the HUD:

410med

But eventually, two things happen. First, you stop swimming in the symbology. Second, you learn after dozens of approaches in the clear as well as in the blind in weather that the system is reliable.

The first part, stopping the swimming is not as easy as it sounds but the trick is this: you have to embrace the theory of the flat panel display above that gives you a symmetry of information: airspeed tape on the left side, altitude tape on the right. Compare the two readouts between the photo of the information on the photo above, then on the HUD display above that. Note the markers indicating speed limits–we call it the “chain,” showing max speeds for configuration. That shifts as you change configuration–say, add or remove flaps.

night cockpit

On the instrument panel, you see the chain in a different color–up top on the HUD, it’s all ghostly green. So two things have to happen. First, you stop looking at colors and discipline yourself to see and heed shapes–but that’s not all. Second, you learn to not look at the side  displays, but rather, incorporate shapes into your peripheral awareness. That is key: peripheral sense. keep both tapes, airspeed and altitude in your indirect awareness, alert for the shapes on each giving you cues to the restrictions. In the case of speed, it’s minimums and maximums (the “chains” counterpart on the low end is the “hook,” or stick shaker limit). In the case of altitude, same thing: level off or descent minimums, or climb level off points, or clean-up altitudes.

You don’t look “at” the HUD information, you look through it but incorporate the information as you go. I once counted all of the possible display symbology and counted nearly 60 pieces of information displayed. You could get lost trying to follow every piece of information, but the key is to just absorb whatever you can from the periphery as things change. Let’s put this into motion on an approach:

(note: the above is an embedded YouTube video. If your browser won’t animate it, just click here to watch)

Notice the slowly decreasing altitude on the righthand tape while the airspeed on the left remains stable. The radio altitude  is counting down near the center–obviously that’s important and so that information is near center of your focus and incidentally, near the touchdown point. The compass rose below the display shows the course track, but the only thing you care about is alignment–again, you’re simply maintaining symmetry by keeping that peripheral information lined up.

This video is slightly different from the 737-800 I fly in that there’s no “flare” cue in this depiction: that’s simply the word “flare” that anunciate above a line that appears indicating where to put the nose for a smooth touchdown. Also, the word “idle” annunciates to suggest when to remove power as the autothrottles pull back for touchdown.

The Flight Management System data-links in the runway data so the HUD target the touchdown accurately.

The Flight Management System data-links in the runway data so the HUD target the touchdown accurately.

The dot in the center of the aircraft symbol is the desired path, the symbol surrounding it–if you’re successful at keeping them aligned–is the “flight path vector,” a symbol indicating where the aircraft is aimed despite the apparent orientation. That is, in a crosswind, you may be canted 20 to 30 degrees to one side or the other, but the FPV shows where you’re actually headed.

This video stops at touchdown, but the HUD does not: when you select detail level 2 or 3 and the ILS antenna supports it, the HUD gives you a runway remaining countdown and centerline steering information–which can be very useful in low-visibility landings and take-offs :

IMG_2391

At my airline, we fly the HUD to the lowest minimum certified, as opposed to other Cat 3 certified aircraft that “autoland.” We never autoland–rather, with the aid of the HUD, the captain hand-flys every minimum visibility approach. Now that I have over a thousand hours in the 737-800 left seat, yes, I’m a “HUD cripple”–and I wouldn’t have it any other way.
