The Half-Truth of Mary Schiavo

Mary Schiavo, former Department of Transportation Inspector General and a frequent critic of airline security, made headlines recently with remarks that flight crews nationwide consider inflammatory, untrue and ultimately, disingenuous.Ms. Schiavo alleged that Known Crew Member (KCM), an advanced security program that currently validates airline crew members’ identity from a national data base, then allows them airport access without further search, creates a security risk for air travelers. But the fact is, Ms Schiavo is aware that the KCM program is the best and most technologically advanced solution to a problem she faced–and never solved–during her tenure as head watchdog at the Department of Transportation.security-den1The KCM database matches crewmembers employment and security certification with a current photo that is kept updated by each airline and the TSA. This is a face-to-face scrutiny and validation even more advanced than the widely acclaimed Global Entry program designed to efficiently certify the identity and security of air travelers entering the United States.

Schiavo knows that airports in the United States are small cities in themselves, comprised not only of the wide-ranging flight support activities required to handle transport aircraft, but also to meet the needs thousands of passengers transiting these facilities daily.

There are food service, passenger service and retail facilities in each airport, mostly on the “secure side” beyond the security screening checkpoints. Thousands of employees performing duties at airport passenger service, retail and restaurant facilities must move in and out of the secure side of the airport and Schiavo is well aware of the access systems such as keyed or electronic access doors for that purpose in every airport.

Never has the 100% screening of all airport workers been considered practical or feasible and therefore alternative employee modes of access have of necessity been standard in order to allow passenger screening with reasonable wait times.

But that’s only the “front of the house” security theater that Schiavo knows co-exists hand-in-hand with a wide open back door access at every airport: vehicles ranging from semi tractors pulling forty-foot trailers to dump trucks and bulldozers are waved onto the airport ramps near fueled and taxiing aircraft daily with only a cursory glance at an identification badge. Thousands of those identification cards alone are deemed sufficient to allow flight line access to contract workers from construction, repair and most frequently, food and retail merchandise delivery, never mind the non-stop caravan of catering trucks wandering the flight line largely uninspected.

Meanwhile, KCM is the only security program assuring that crewmembers are who they say they are and have current and valid access credentials. Crewmembers are but a fraction of the multitudes granted airport access, yet they are the only group whose identity and legitimacy is positively verified. This, after background checks, random drug tests and no-notice personal items inspections by the TSA.

image

The irony is, Schiavo singles out those crewmembers and the most secure, updated, state-of-the-art security access program for unwarranted, alarmist sound-bite criticism. If anything, KCM should be the model for all airport access programs. The worst part of her criticism, however, is her allusion to the September 11th hijackings, implying that “Known Crew Member” is in any way risking another such a tragedy.

Certainly, the former Inspector General of the Department of Transportation knows all of the above. That she chooses to mislead the traveling public on such a crucial issue is both disingenuous and deplorable, and her September 11th allusion is unforgivable.

All the Wrong Answers to the GermanWings 9525 Crash Questions

As is always the case after an airline disaster, the media and shortly thereafter, regulators rush to propose a quick but ill-advised “fix.”

In this case, the proposed quick fix falls into one of two useless but unavoidable categories: technology and regulation.

In the first case, technology, the spectrum of bad ideas runs from remote control to cockpit access override. That reminds me of earlier, fun days flying a supersonic jet that began to accumulate pilot fatalities in low speed, low altitude ejections. The engineering fix was to install a drogue chute that deployed upon ejection to hasten the main parachute deployment. That worked fine until the first high speed, high altitude ejection when the drogue chute deployed at Mach 1 and the G forces cut the pilot in half.

image

Back to today, talk in this airline tragedy is of an even more bizarre solution: remote control “intervention:” taking over the aircraft flight controls from the ground. Beyond the fact that I as a thirty year airline pilot will not set foot in a cockpit that can be commandeered by remote control, consider the added layer of vulnerability: beyond two pilots who “could go rogue,” you’ve now introduced an entire spectrum of people, entities and hackers capable of taking over the jet. Better? Really?

Yes, some type of cockpit access intervention “might” have worked to restore this one pilot to his rightful place, while opening every cockpit henceforth to an outside “intervener” which defeats the necessary cockpit exclusion no one disputes is necessary: if one can, eventually all can. Better?

Then there’s the regulatory crowd, for whom the semi-annual FAA pilot physical, recurring spot checks, blood and urine alcohol and drug testing is not sufficient to validate a pilot’s fitness to fly. What’s next, a psych exam before brake release? A background check beyond the extensive background checks we all have already? A credit report before each instrument report?

image

Here’s the real problem: there are no quick solutions. Yet that’s what the public “demands”–for now, but only for now. The fact is, in Texas alone there have been 257 traffic deaths so far this year, yet no one’s calling for a twenty mile an hour speed limit or any other radical but certain solution. Yet the “1 in 11,000,000 chance” (Harvard 2006) of dying in a plane crash brings a public outcry for an immediate technological or regulatory intervention.

I watched Air Force One arrive once, the president bounding down the stairs and greeting the crowd as law enforcement snipers on rooftops looked on. No “remote control triggers,” no on-scene sharpshooter credit checks. Rather, the thinnest final line ever drawn: trust.

image

In the end, that’s what it comes down to anyway: trust in your flight crew. There’s no simple solution to the rare and tragic occurrence that just transpired over the French Alps. But there is real danger in half-baked solutions that just add more layers of vulnerability to what is already 11 million to 1 odds in an airline passenger’s favor.

Despite the media frenzy driving an out of scale public reaction, no “solution” is better than a hasty, ill-conceived technological or regulatory bandaid that increases the very danger that started the panic in the first place.

If you don’t trust me in the cockpit, fine: trust yourself on the road. Your odds there are astronomically worse, if that matters to you, but at least the flying public will remain safe.

Can YOU Stop A Jetliner on a Wintery Runway?

LaGuardia Airport

LaGuardia Airport

Can YOU stop a jet on a winter runway?

Whenever an airliner slides off a taxiway or runway in winter conditions, the public and the media asks dozens of questions related to one overriding concern: how could this happen?

But for every other flight that lands on a winter-affected runway without incident, there were dozens of questions correctly answered by pilots related to THIS overriding concern: how can we assure that DOESN’T happen?

I’ve been flying in and out of LaGuardia and Washington Reagan all winter, accommodating ice, low visibility and contaminated surfaces in what has been an exceptionally vigorous winter storm season. The questions and correct answers required to assure a safe flight under such conditions are neither straightforward nor simple. Here’s the decision process–YOU decide what to do.

image

First, before we even depart for an airport affected by winter weather, we think about the factors that affect our landing: weight, wind, landing distance required, and runway surface conditions. And there are no easy answers any of these questions.

Weight comes first: considering stopping, you’d want weight to be the lowest possible, right? If only it were that simple: the primary, most variable weight in flight is fuel–if you reduce fuel weight to the bare minimum, you also reduce flying time to the bare minimum. The facts of life when flying into a major metropolitan airport include delays–demanding MORE flying time, thus more fuel and thus more weight. If you have only the minimum fuel aboard required to fly the distance, you are screwed: at the first delay (and airborne holding assignments of up to 30 minutes are typical) you must divert.

What you need to do is carry enough fuel to fly the miles AND accommodate typical, historically predictable enroute holding. We’ll have to be sure that we can still accommodate that weight on landing (checking landing distance charts) but that’s a separate question to be dealt with: for now, tank as much fuel as required to fly the distance and hold for a reasonable duration enroute.

IMG_6233

We don’t leave the rest of the questions for arrival, but we do answer them late in the flight when the variables have been sorted out: once we’re in the terminal area, we finally can predict an accurate landing weight.

So we request the data-linked landing distance chart for our specific weight which is calculated by computers back at our tech center and sent to our on-board printer. Problem for you is this: the chart also has variables you must resolve: what is the runway condition, and what is the braking effectiveness?

Those two variables can not be definitely determined because the informational reports are both very subjective: the “runway condition” must be determined in reference to varying standards. Our airline calls a runway “contaminated” when 25% of the landing surfaces is contaminated by ice, standing water or snow.

Another airline may allow 30%, another 60%, so there’s never any “contaminated” determination available other than reports from previous company aircraft. But even those are subjective–how do you eyeball 75%–and in winter storms, conditions can worsen by the minute.

image

Braking effectiveness is another subjective report: what I consider “fair” braking for my jet (and I report this to the tower after landing based on what I just experienced) might be “good” for a lighter regional jet or “poor” for a heavier aircraft or and aircraft with less effective brakes. And, in heavy precip, that can change drastically in just minutes.

The landing distance charts reference “good” or “fair” in the conditional determination of braking effectiveness–but you now know that “report” is vague at best. Still, you must decide which calculation to use.

There’s also more than one chart for landing distance. The first one assumes that you touch down at the Visual Approach Slope Indicator (VASI) aimpoint which is about 1,500 feet from the runway threshold. There’s another chart that computes stopping distance from the visual touchdown markings on the runway some 500 feet prior to the VASI aimpoint. That chart, with the additional distance from the earlier touchdown point, may allow you to land based on stopping distance.

image

But can you accomplish that? The “you” is key–no one on the ground can answer that. Ultimately, the captain decides, and here’s what he’s thinking: what are the winds? A tailwind will make that very difficult, a headwind will help. But can you count on either wind report? Those reports, like “braking effectiveness,” have a very short shelf life–winds change minute by minute. Do you think your landing wind is reliably a headwind, or at least not a tailwind? Again, YOU have to answer that based on subjective reports.

As far as the visual touchdown aimpoint, are you going to be transitioning to this new, shorter target from an instrument approach, which has a more distant touchdown point more like the VASIs? If so, do you have adequate distance, time and visibility to do so? And the skill?

Finally, landing rollout must be done exactly right: spoilers deployed, reverse thrust promptly initiated at the proper level, and brakes applied promptly and correctly. That sounds easier than it is.

First, spoilers normally are automatically deployed–but that deployment needs certain prompts: main wheel spin-up is a primary trigger, and patchy ice may keep wheels from spinning, delaying auto deployment, even as you eat up critical landing distance. Or, like last month, I landed my 737-800 on a wintery DCA runway without the auto-spoiler system working. I agreed before dispatch on the flight that I could and would do so manually. My judgmental call, a fact of life in airline flight operations.

Regardless, the point is, the crew must assure spoiler deployment and effective reverse thrust AND full braking–all in a millisecond when landing distance is critical.

As crucial, you must put the jet down on the exact spot–neither before nor absolutely, not beyond–and put it down firmly to ensure wheel spin-up, essential for traction and auto-spoilers. If you’re the ignorant smartass getting off the plane after that trying to be witty by saying “You must be a Navy pilot, that was a carrier landing” or “I guess the brakes work,” I’ll ignore you–but the crew will write you off as an ignorant smartass just the same.

image

There’s no feeling worse in the cockpit than the anti-skid system releasing the brakes on rollout, even if you’ve done everything correctly, but that’s essential too: the system applies braking force to the very brink of a skid, beyond which there’s no braking, just sliding. If you’ve calculated your stopping distance based on “fair” reports, you can expect some releasing as the brakes do their job. All the more reason for a firm and accurate touchdown.

I expect and require every landing to be on the correct speed (faster makes stopping more difficult) and on the right spot, even at DFW Airport with miles of runway to spare, simply because it must be (for me) the rule rather than the exception when I fly to LaGauardia, Washington Reagan or Santa Ana-Orange County with shorter runways. “Pretty” landings are a Hollywood contrivance and have no place in the actual profession.

When we stop safely and exit the runway, that’s because we correctly solved the puzzle: weights, speed, touchdown point, winds, and braking distance. For passengers, that means a safe trip completed. For the cockpit crew, the work is only beginning: all of these variables must be dealt with successfully again in order to execute a safe take-off or abort on that same winter-affected runway.

The airline industry in the United States has an enviable safety record, which is why the very rare incident gets so many media headlines. The real news is, overall, airline pilots are doing their job very well.

Air Travel, De-Icing and Delays: The Real Deal.

Network news media love a screaming headline, even if they have to fudge the facts to suit the rhetoric. But here is the reality behind the wailing and gnashing of teeth regarding recent ice-related delays at major airports: the airlines did a damn good job given the challenges heaped on them in this storm.

As a captain, I flew a 737 trip in the middle of the week in the slush and snow out of DFW. Here is your chance to bypass the media frenzy (NBC News carefully crafted “9 hour delay for passengers”–quietly admitting later that it wasn’t on-board) and watch the flight evolve despite the weather interference.

At 06:10, a phone call from crew schedule woke me up. I had volunteered to fly a trip that day and they offered one, a turn to John Wayne Orange County (SNA) scheduled to depart at 10:10. I agreed to fly the trip.

Normally, it takes me 35 minutes to drive to DFW. I left my house at 6:45 to allow extra time for the slush and snow snarling the highways.

I arrived at DFW an hour later, an hour and twenty minutes early. The jet was parked at the gate, had been all night in the freezing precip, so I went aboard and started powering up systems. A quick check of the wings and fuselage confirmed what I assumed driving in: we’ll need a good de-icing on the wings, control surfaces and fuselage.

Let’s get more specific about aircraft icing. First, we need to remove the accumulated ice. Second, we need to prevent more ice from re-forming on aircraft surfaces. De-icing can be accomplished by a number of different fluids under pressure. “Anti-icing” is provided by a different, specifically designed fluid that chemically inhibits the adherence of ice on aircraft surfaces.

image

In our case, the ceiling was low and visibility limited by ice fog, confirming the critical temperature-dew point spread that leads to condensation which of course would freeze on any cold surface. That means both de-ice and anti-ice will be required.

Anti-ice fluid effectiveness varies with temperature, and rate and type of precipitation. The duration of anti-ice protection declines as various forms of moisture increase. So, gauging the time–called “holdover time”–is a call that must be made by the flight crew based on observation of conditions actually occurring.

You can tell when anti-ice fluid has been applied to a jet because it will be colored either brick red-ish or lime green. The intensity of the color cues the cockpit crew as to the fluids declining effectiveness–it fades as the fluid loses the ability to inhibit icing. We actually check visually that from inside the aircraft prior to takeoff.

A side note about the fluid color. Most airlines now use the green fluid because the red was difficult to distinguish from hydraulic fluid as it dripped from crevices and bays on the aircraft, sometimes several flights downline from the original de-icing treatment. I learned long ago how to differentiate the two: propylene glycol, the main ingredient in anti-icing fluid, smells and tastes sweet. Skydrol hydraulic fluid is bitter. Yes, I’ve tasted both in the thirty years (and counting) I’ve been flying jets and laugh if you want, but it saves all aboard a needless and probably lengthy maintenance delay.

image

Another unseen complication that adds to the icing mix is jet fuel. The worst case is with fuel remaining in wing tanks after a flight at high altitude. The fuel in the tanks become super cold due to the temperature at altitude (often -50C or less) and as a result, the wing surfaces both upper and lower are super-chilled, causing any moisture in the air to freeze on contact. Explain that to the guy sitting next to you griping as we de-ice on a sunny, clear day: humidity plus ice-cold metal surfaces can add up to wing icing that must be removed: we can tolerate no more than 1/8″ of mere frost on the underside of the wing only. Any other airfoil contamination must be removed before flight.

Clear ice on wings is not easy to see from the cabin, particularly the area near the wing root, which is critical on aircraft with tail mounted engines like the MD-80 and -717, because upon wing flex as rotation and liftoff occur, any wing root ice that breaks loose into the slipstream could easily fly back along the fuselage to be ingested by either or both engines, with potentially disastrous results.

So why don’t aircraft have heated wing surfaces? Actually, most MD-80 upper wing surfaces do have an electrically heated thermal blanket on top of the inboard-most portion of the wing surface. But, not the curved wing root joint which is not visible from the cabin. So, you’ll notice a lot of MD-80 aircraft having to de-ice in even the slightest icing conditions.

image

In our case, I knew the fuel pumped aboard for our flight would have the opposite effect. At DFW, the fuel is stored underground and pumped aboard from a hydrant, not a truck. The effect would be to warm, not freeze the wing surfaces. That would help with de-icing, but we’d still require a thorough dose of Type-2 de-icing fluid to clean ice off the jet.

By 9:10, the official crew check-in time, there was no sign of a first officer. I started the process of printing a flight release and agreeing on a fuel burn, as well as the complex process of determining takeoff speeds, made more complicated due to the presence of slush and snow on the runway. Any type of contamination, from pooled water to slush to ice can impede both acceleration and deceleration. Both maximums (takeoff and stopping) must be accurately calculated and while there is a published “runway condition,” the actual calculations are very much a realtime, eyeballs-verified assessment: I’ve broken through an undercast during an ice storm as we approached DFW only to find that just the first two-thirds of the runway had been cleared–a fact not noted on the official field report. That lopped off about four thousand feet of useable braking surface.

At 9:30, forty minutes prior to pushback, still no sign of a first officer. The roads are awful, as is the traffic, so I’m not surprised and I’m glad I left home as early as I did. I called Crew Tracking, catching them by surprise as well: in this winter storm, there were plenty of stuck, stranded or missing crewmembers. They hadn’t noticed.

I resigned myself to going out into the sleet to do the exterior inspection myself, planning to have all preflight duties complete in case the first officer should show up at the last minute. Here’s an up close look at the leading edge icing:

image

and the ice on the wing trailing edge:

image

Engine covers were installed, a very smart preventative measure to prevent icing, but which would require maintenance removal and documentation. I radioed maintenance to get in the cue for this required maintenance and fortunately, American Airlines had well-staffed maintenance for this shift. But again, they too had technicians who, like my F/O, were stuck in the ice storm snarled traffic, slowing things down.

image

With the exterior preflight complete, I requested the upload of navigation and performance data as well as our clearances. And I took a minute to call the Crew Scheduling Manager on Duty to suggest that they grab the deadheading 737 first officer sitting in row 20 and reassign him to fly the trip. He said if the duty legality limits worked, that’s what he’d do.

By 10:00, the conscripted first officer was in the right seat, having agreed to the reassignment: he’d fly the leg to the west coast, his home base, and rather than going home, he’d also fly the leg back to DFW and only then deadhead home, if possible. Just one more crewmember going the extra mile to make the flight operation work.

We pushed back nearly on time (10:21 vs. 10:10) , but the ramp was congested with ice and slush, slowing everyone down even further. The precip had stopped, the ceiling had lifted to a thousand feet and the temperature-dew point spread had widened, all of which meant less chance of ice formation. Our holdover time would expand, allowing us to de-ice on the ramp rather than at the end of the runway. Essentially, that made for a shorter wait for all aircraft: if there is freezing precip, or any precip in freezing temps, all de-icing would have to be done at the end of the runway, meaning long takeoff delays.

image

Taxiing a seventy-five ton tricycle on ice and slush is tricky, requiring slower speeds and a critical energy management: too slow and you’ll have to add excessive power to restart movement, slinging ice and slush at other aircraft. But you also need almost zero forward inertia to maintain nose gear traction in any turn, aided by asymmetric braking on the main gear into the turn. It’s a dicey operation that takes extra time.

We kept the flaps retracted on taxi-out so as to not accumulate any slush or freezing water on the underside of the flaps, a potential problem during flap retraction. Our miles-long taxi from the east side terminal to the west side runway gave us plenty of time to assess the surface conditions and fine-tune our power and speed plans.

We finally lifted off nearly fifty minutes after taxi-out. Through route shortcuts and favorable winds, we made up some of the lost time, arriving twenty-eight minutes behind schedule.

I believe my flight was more typical of all flights during an unrelenting ice storm, but mine isn’t the one craftily worded into a horror story by the media. Regardless, the fact is that icing makes flight operations complex, difficult and challenging. Yet more flight operated in the same way mine did–slow, careful, successful–than the media version of a few unfortunate cases. I take it as a compliment that the reality of these winter flights was a success story leaving the media very few flights to turn into their typically overblown horror stories.

By the time I got home nearly fourteen hours after voluntarily accepting the challenging flight assignment, the network news was already sensationalizing the “impossible” travel situation created by SnoMIGOD 2015 which dumped an unprecedented amount of snow and ice on DFW and Dallas Love Field. At least I knew the facts were not as they’d have us believe–and now you do too.

Air Travel Mythology: The “Aborted Landing”

Air a Travel Mythology: The “Aborted Landing”

In social settings, I never bring up the fact that I’ve been an airline pilot at a major carrier since 1985. Because when I do, the mythology springs forth: tales of “harrowing” flights, near disasters, plus lost luggage (not my department anyway).

The flight myth most typical is, in passenger-speak, something like this: “We were about two feet off the ground when the pilot ‘gunned it’ and we shot straight up.” Gunned it?

Ah yes: the go-around, as we call it. We don’t call it “aborted landing” and in fact, until we get on the runway it’s not a landing anyway. Even after touchdown, the only option other than stopping is a “rejected landing,” which is a methodical procedure to get back into the air safely.

The main point is this: all of these options are planned for, procedurally set out and practiced, and in a nutshell–not a big deal.

fd1

Here are the facts, step by step, of a missed approach.

First, the urban legend needs revision. From an airline pilot standpoint–and this is the airline philosophy, in writing–a missed approach is considered a successful approach. In other words, landing is not mandatory for a successful approach. In fact, unless all of the many restrictions upon which a landing is predicated are met, a missed approach is the desired outcome.

There are a number of reasons why a missed approach may be required and the most common reason is not the one most people think of: weather. Rather, is the more mundane issue of spacing.

More specifically, that “spacing” refers to the distance between aircraft landing and ironically, this is typically a good weather problem. In bad weather, aircraft are well-spaced by radar and further, speed is typically assigned by the air traffic controllers. On a clear day, aircraft are allowed to “see and avoid” and thus are not spaced as far apart, nor is the speed as rigidly assigned.

So, now and then one aircraft on final approach may not have enough space behind another aircraft just touching down, which could mean the first aircraft might not be off the runway before the following aircraft would touch down. That’s a no-fault situation: maybe the first aircraft needed to slow down earlier than normal, or, as at DFW today, due to construction some runway exits may be closed, requiring a longer landing rollout.

BA 747

Or, often enough, an aircraft is cleared for takeoff as you approach and they might take longer than expected to roll. That’s routine and actually, it’s their runway once they’re cleared for takeoff. So, we may need to go-around.

The pilots in the second aircraft can see the spacing problem develop and there may be a few things that can help: you could slow to your final approach speed–but I also consider the plane behind ours and how that affects his spacing on our aircraft.

My rule of thumb is usually this: if the aircraft ahead touches down or starts takeoff roll and we’re still at 500 feet or higher, it’ll probably work out. Less? We’ll likely go-around. When we do, the process will be routine and simply, methodically by the book: smoothly add power, arrest the descent, bring up the landing flaps and their drag, retract the gear and smoothly climb to the assigned missed approach altitude and following the prescribed course.

No big deal from the cockpit, but it takes you by surprise in the cabin where you can’t see the situation developing. When power is added and the nose pitches up, the sensation in back is much more dramatic, particularly behind the wings and especially near the tail (ask any flight attendant) where the swing is more pronounced.

Sometimes the power can be overly dramatic: we have a power setting designed for a go-around, but it’s predicated on a last second escape from the lowest descent altitude on the approach–50 feet above the runway, in the Boeing 737-800 I fly. But seldom is the missed approach executed at that rock-bottom minimum, so that much power isn’t really necessary.

image

 

Trouble is, some of the older jets like the MD-80 have autothrottles that know only to set the maximum setting if the go-around power toggle is activated. That causes a dramatic pitch up that may feel, in the words of the immortal Dr. Dole at USC Flight Safety and Accident Investigation Center, that you’re “climbing like a stripedy-ass ape.” Startling to say the least and why many pilots of those older aircraft disengage the autothrottles and manually set power on a go-around from a higher altitude.

Newer jets like the Boeing I fly today have two go-around power settings available with the autothrottles engaged, one with the maximum power response, one with a reduced, more comfortable setting.

A go-around from an approach minimum altitude is the exact same procedure, only with the full power setting, which will make the maneuver more pronounced but nonetheless, routine. That’s necessary for safety: we want maximum terrain clearance with no delay, so the exact same procedure is followed, just more aggressively due to the full computed thrust used.

image

When I see the need for a go-around developing, the first thing I do is talk to the other pilot, getting us both ready to execute the litany of steps if need be. If we’re down to the approach minimums, there’s really nothing to discuss: we execute the standard go-around maneuver.

Traffic problems and spacing are the usual reasons for a go-around, but there may be the occasional go-around due to weather minimums. There’s no “gunning it” or fire-walling the throttles like in the Hollywood depictions, just a methodical and prompt setting of the required engine thrust and an arrested descent, then climb.

In either case, don’t expect to hear much from me on the PA, because in a go-around both pilots need to focus on flying: the altitude, the procedural track, the aircraft configuration and speed. If we’re going around due to weather minimums, we’ll also likely be setting up the navigation and securing the clearances to divert; if not, we need to get re-sequenced back into the landing pattern. None of that on a two man crew works well solo, which is what a PA would require.

So I’ll get to it when and if I can. If not, explain all this to the guy next to you, and relax. Because now you know a go-around is just routine.
