Cockpit Chronicles: Fly Rio!

by Kent Wien on Oct 21, 2011

Occasionally the airline will offer pilots the chance to fly for a month out of another base when they’re short a few pilots at that city. I remember flying with one of these temporary duty (TDY) pilots who came up to Boston from Miami. I asked him what trips he usually flew out of Miami and he began to tell me all about Rio de Janeiro.

The conversation included some good pointers about the hazards of flying in Brazil.

He pointed out that there’s a note in our manuals that talks about celebratory balloons near the city. Apparently, it’s not uncommon for Brazilians to put together huge balloons especially at night, attach them to a pallet or some other structure and light a fire under the canopy. The Miami pilot even claimed that a propane tank has been known to be the fuel source.

After nearly hitting them on two different occasions, he sought out to warn other pilots of these inflight obstacles.

He said he had even seen one while climbing through the clouds.

A quick look at YouTube shows the launching of a few of these balloons such as this one:

The Miami co-pilot went on to describe the difficult radio reception over the country as well and we talked about the midair collision between a 737 and a corporate jet down there.

After struggling to close my jaw from shock, I had to ask him, “Why do you bid those trips?”

He claimed it was for the inexpensive (at the time) and abundant beef dinners, although since he was single and rather shiny, I suspected the women in Rio were a big part of the attraction.

Now that I’m flying out of New York, I’ve had the opportunity to fly a handful of Rio de Janeiro trips-enough to at least describe some of the challenges and benefits of this long-haul flying.

My first trip to Brazil almost didn’t happen. The inbound airplane had been struck by lightning and we were initially told to wait until the early hours of the morning for a replacement. Fortunately it was decided that we should go back home and sleep overnight before continuing the next morning at 9 a.m., twelve hours after the original departure time. While the passengers were accommodated in hotels, there was no provision in our contract to put up the pilots and flight attendants. Some of the commuting flight attendants spent the night in operations and the other pilot and I went back to sleep in our rented apartments in the area (i.e. the “Crash Pad.”)

The rare daytime flight the next day made it possible to glimpse much of the Amazon rain forest along the way and to appreciate just how massive this country is. To give you an idea of just how big Brazil is, our typical crew rest break on the 9 hour and 15 minute flight from New York is about 3 hours. On the way home, it’s possible for the first pilot to finish their break before ever leaving the Brazilian airspace.

I’ve flown in some areas with poor ATC reception, most notably Piarco radio in the Caribbean, but nothing has been more challenging for me than Brazil. The VHF transmitters are spread out over vast areas. Often two transmitters will be operating at the same time which causes a distracting echo over the speaker. The HF radios we use when flying across the Atlantic would be an improvement from this system.

Traditionally they’ll give you two VHF frequencies at a time, a primary and a back up and we find ourselves choosing the least annoying one as the flight progresses. It’s possible to fly for hours while talking to the same controller on a variety of different frequencies spread out every 200 miles. I suppose, to be fair, it’s not easy to install more transmitters in the dense Amazon jungle.

As we arrived early in the morning at the hotel, I was startled to see a massively vertical mountain shooting up from the side of our hotel building. The waves below the mountain were more powerful than any I’d ever seen, and I stayed awake for a while to watch them hit the rocks and shoot up over spectators perched at lookout points along the road.

There’s plenty to see and do in Rio, but alas, we’re usually asleep for much of the first day there and unable to enjoy the sun.

Ever since the exchange rates for the Real were changed, the dollar doesn’t go as far as it used to. It’s not quite as expensive as some European destinations, such as Zurich and Paris, but it’s close. Dinner at an inexpensive cafe three blocks inland from the Ipanema beach ran about $30 with drinks.

I’ve recently become interested in paragliding (watch for a future Cockpit Chronicles on that) so I hitched a ride to the top of a local mountain to watch the hang gliding and paragliding pilots takeoff on tandem flights for tourists to Rio. I elected to save my money and enjoy the spectacular launches from the platform instead of flying as a passenger. Besides, hopefully I’ll get the chance to fly my own paraglider from the hill someday.

Even though it was only 72 degrees, I managed to get rather sunburned while filming all day, but the footage was worth it:

In order to see more of the city, I knew I’d have to get a longer layover there. Fortunately, once a week during the summer we’ve had a six-day trip that includes four days there instead of just a day and a half. I managed to snag one of these in early October much to my delight.

The captain and his flight attendant fiancée on this long trip, happened to be friends of mine who were formerly based in Boston, so we made plans to see the Christ Redeemer statue that overlooks the city. They also wanted to try a tandem hang gliding flight, and of course I knew just where to take them.

A shuttle bus takes you up to the top of the Christ Redeemer platform and it was probably more scary and dangerous than the hang gliding flight for Susan and John. The expansive 360 degree views of Rio from the top of this mountain made it worth the risk.

Our flight home was delayed due to another late inbound aircraft, so we had plenty of opportunity to take a long nap before leaving the hotel. These daytime naps are critical as the flight time is well over ten hours on the leg home to New York and that extra sleep comes in handy when you’re working your way through the Inter Tropical Convergence Zone, an area of thunderstorms that have parked themselves near the equator while lighting up the sky.

Since Susan was working the galley, I had her explain how our crew meals are prepared and served for a video used in last week’s Cockpit Chronicles during Gadling’s week-long focus on food and travel.

I managed to snap a few pictures of these storms that lit up the clouds around them like a built-in long range flash for my camera.

After the first few trips I was surprised at how wide-awake I was during the flight. But it was a different story the next day. It was hard to recover sleep from the all-nighters but I have to admit, Rio de Janeiro is a welcome change from the European flying I’ve become accustomed to.

And that’s probably the best part about working for a major airline. If you get tired of flying in one area, you can switch to a different base permanently like I did in May of this year or for as little as a month just to try a whole new type of flying.

Cockpit Chronicles: VideoâFood in the cockpit. How it’s prepared and what is served

by Kent Wien on Oct 12, 2011

“I’m getting kind of tired of these chicken Caesar salads.”

I said those words just a few months into my career at American. The statement resonated loudly after I was furloughed and flying for a freight airline with barely a bottle of water on board, so I vowed that I would never complain about a crew meal again.

In fact, when I came back to AA I nearly cried when a flight attendant entered the 727 cockpit and asked us what we wanted to drink.

Now, after ten years of international flying, mostly to Europe, I’ve enjoyed more crew meals than I probably should have. Warm dishes on an airline flight might be foreign to today’s passengers and even some of our domestic pilots, but on the international side we still enjoy food just as it was in the earlier days of airline flying.

The usual transatlantic daytime flight might include appetizers, such as nuts and cheese, salads, a main course with an overabundance of bread and a slice of cheesecake perhaps, followed later by a Sundae or cookies. Before landing in the afternoon, there’s often a cheese plate or fruit dish, followed by a pizza or steak sandwich.

Honestly, it’s too much. But if you’re paying for a business class experience, over indulging every now and then isn’t bad. For pilots however, these crew meals can add more pounds in the first year of international flying than during a freshman year in college.

I limit myself to just the nuts as a starter followed by the salad. Later, if there’s any fruit available, I’ll have some of that, or if it’s morning in Europe, the cold cereal is a good choice. Anything more and I begin to feel overly tired during the overnight flight across the pond. Since I’ve cut back I’ve noticed a definite slackening of my uniform pants.

Typically three meals are put on for the three-pilot cockpit crew, two items the same, often chicken or steak and the third perhaps being a pasta dish.

Most co-pilots give the choice of meal to the captain, and the captain often defers back to the co-pilot. It can become comical at times; neither pilot wanting to make what is probably the least important decision of the flight. Alas, it’s typically decided that whoever is flying the plane for that leg should choose.

I’ve enlisted the help of our flight attendant Susan, who made a brief appearance in my Boston to Paris video seven years ago, to appear again in front of the camera to show how she manages the cockpit and passenger meals for a 10½ hour flight from Rio to New York.

Notice just how busy Susan is before boarding. As the “number five” flight attendant out of nine aboard our 767, she’s ‘the cook’ up front, responsible for not only preparing and cooking the meals, but setting up the galley on the ground.

Passengers in the back also enjoy a hot meal, and there’s another flight attendant with three ovens getting ready to prepare that food as well.

Every month the meal types and even the kind of cheese in the appetizer change. Some plates are exceptional-a white chocolate glazed chicken dish sounded terrible but turned out to be fantastic-and some I’ve avoided after just one bite, such as the foie gras stuffed chicken.

The ‘insert’ shown in the video is mostly an international custom. It keeps the pilots from having to call back every time they’re ready for more water or soda. It’s brought to the cockpit only after takeoff to prevent anything loose from bouncing around the flight deck.

The sundaes and baked cookies aren’t normally part of our meals, but some of the nicer flight attendants will still offer them.

In the past, no two pilots could eat the same meal, and they had to be served at different times. At my airline, these restrictions have been relaxed, however.

For the past year or so, I’ve taken to capturing some of the crew meals with a camera. Apparently I fall into the crowd that likes taking food pictures. The gallery below shows some of my favorite crew meals of all time:

Photo of the day – Brazilian shopkeepers

by Alex Robertson Textor on Aug 18, 2011

Two Brazilian shopkeepers are the subject of today’s Photo of the Day, snapped by Flickr user jrodmanjr. This image grabbed my eye for many reasons: the intensity with which the two men are engaged in conversation; the grandness of the building itself; the sidewalk’s black and white tiles; the interior neon ceiling light fixtures; the back door, ajar and luminous. This is an evocative scene, and it captures a piece of Brazil.

Perhaps you have an image on your hard drive of another riveting human interaction. Perhaps you’d like to share it with a wide audience. Perhaps you should upload said image to the Gadling Group pool on Flickr. Perhaps, finally, it will in turn get chosen as a future Photo of the Day.

To everyone uploading photos to the Gadling Group pool on Flickr: For the umpteenth time, please make sure that your images can be downloaded. If we cannot download your images, they will not be chosen as future Photos of the Day. I am talking to many of you, but especially to baby_mongster, whose photos I love and am never able to select.

Cockpit Chronicles: There’s more behind the Air France 447 crash than pilot error

by Kent Wien on Aug 12, 2011

Recently a couple of pilots found themselves in a situation that was foreign and perplexing to them; a scenario the designers of the airplane hadn’t fully expected. They fought their way for 3 minutes and 30 seconds while trying to understand what was happening after a failure of one of the pitot static systems on their Airbus A330. At times the flying pilot’s inputs exacerbated the problem when he assumed they were flying too fast rather than too slow.

Because they hadn’t seen anything like this in the simulator, and the airplane was giving conflicting information, the recovery would have been all the more difficult.

Pilots are taught that an erroneous airspeed indicator can be countered by paying close attention to their pitch and power. It sounds so simple that many pilots wonder aloud, just how anyone in the situation could mess it up.

In the early morning hours of June 1st, 2009, the pilots of Air France flight 447 were working their way around thunderstorms while flying from Rio de Janeiro to Paris in the widebody Airbus A330.

A faulty pitot tube created a situation where any changes in pressure resulted in fluctuations in the airspeed indicator. To understand how difficult it is to recognize this problem and then correct for it, let me use the following analogy:

Imagine you’re driving a car at night. You come down a hill and you feel the cruise control back off on the gas to prevent the car from going too fast. Just as you look down at your speed noticing that it is, in fact increasing, a siren and lights go off behind you. A police car has woken you up from your late night drive.

Instinctively you kick off the cruise control and apply the brakes. The speedometer indicates you’re still accelerating, so you press harder on the brakes. Your car has now decided that because you’re trying to slow so quickly, it will shut off the anti-skid braking system and allow you to use manual brakes. You then skid off the road and into a ditch.

Based on the released information about one of the most mysterious accidents in recent history, it appears the pilots of Air France 447 faced a set of circumstances similar to our driving example.When flying in turbulence, it’s important to watch your airspeed. Flying too fast will result in a situation called mach tuck, where the nose can slowly pitch over and the controls lose their effectiveness.

Flying too slow can result in a stall. Not an engine ‘stall’ as might be incorrectly reported by the press, but an aerodynamic stall where the wings aren’t developing enough lift, and an immediate increase in the airspeed is needed to recover. Here’s a tip for reporters. In aviation, the term ‘stall’ will never be used to describe engines that fail. Ever.

Up at altitude, the difference between flying too slow and too fast can be as little as 20 knots. It’s called the ‘coffin corner,’ a morbid term used to describe narrow band of airspeed that we need to maintain.

In this 767 example above, the airplane has a very safe margin between
too slow and too fast, as shown on the airspeed indicator on the left.

While working their way around clusters of cumulonimbus clouds in the inter-tropical convergence zone that night, our two first officers (the captain was in the back on his planned rest break) did their best to stay away from the weather.

A side note: whoever takes the second break is usually the pilot who made the takeoff and who will also make the landing. So the relief pilot (who’s a type-rated copilot) took over the flying related duties while the captain slept.

Back to the flight: During turbulence, maintaining that speed can be more difficult, much in the way it’s tough to hold the speed in a car going over hills. You may look down after studying the weather only to notice that the auto throttles aren’t holding the .80 mach speed you have selected and the airplane is now at mach .83 and accelerating. In a moment, the clacker goes off, indicating you’re now exceeding the normal cruise speed of the airplane, which certainly gets your attention, much like the sirens of the police car in our example.

In the case of Air France 447, the autopilot kicked off in response to the overspeed, and was followed by a warning Airbus calls a ‘cavalry charge’ sound which is designed to get your attention quickly. About 30 seconds later the auto throttles were turned off manually and the throttles were pulled back, but it takes an eternity to slow down such a slippery airplane, and it may have seemed to the flying pilot that he was still accelerating anyway. So he pulled the nose up, an effective way to slow down in a critical situation like this. (See last week’s post on the eight ways to slow a jet.)

Amazingly, as the airplane climbed from 35,000 feet to 38,000 feet the airspeed continued to increase, at least that’s what it looked like on the flying pilot’s side of the airplane. He must have been surprised then to hear the stall warning activate moments later, indicating that they were flying too slow.

The other pilot likely noticed the airspeed on his side was decreasing, and perhaps because he saw the difference between both airspeed indicators, he’s heard to say on the recording that “we’ve lost the speeds.”

They had slowed from 275 knots indicated to 60 knots, at which point the airplane went into a mode called ‘alternate law’ which meant the automatic protections that kept the airplane from stalling were removed.

To make matters worse, the stabilizer trim moved from 3 degrees to 13 degrees nose up, which meant the airplane may have needed almost full nose down inputs on the stick just to fly level.

And to further confuse and confound the pilots, it’s recently been reported that as the airplane slowed further, the stall warning stopped. When max power was applied and the nose was lowered at one point, the stall warning came back. This is opposite of what the pilots were looking for in a recovery.

The airplane ‘mushed’ in a 15 degree nose up attitude all the way to the water, at a rate of 11,000 feet per minute.

We occasionally train for unreliable airspeed indications, but it isn’t covered during every recurrent training period. Stall training is often limited to the low altitude variety, which is far less critical than one occurring at 35,000 feet. I’m certain training departments all over the world will soon be required to train for high altitude stall recoveries.

Since this will take some time to become a requirement, on a recent simulator session, I asked my instructor to give me a loss of airspeed scenario at altitude. I told him I’d prefer to have the failure at any random point during our four hours of simulator time that day.

When he eventually failed it, causing the airspeed to slowly increase, I immediately pulled the throttles back and raised the nose a bit. The non-flying pilot simply said ‘airspeed’ which I thought was obvious, as it appeared to me that the airplane was accelerating rapidly and I was doing my best to get it back under control.

But on his side, the airspeed was dropping rapidly. When he said “airspeed” he actually meant that the airspeed was slowing and that I needed to do something about it. I finally looked over at his side, and saw that his speed was actually decreasing while mine increased. This all occurred within ten to twenty seconds.

I immediately lowered the nose and told him that I suspected my airspeed indicator had malfunctioned. Since my indicator was useless, I offered the airplane to him.

It’s easy for pilots to harp that “pitch and power equals performance” but it’s not easy to ignore the instruments you’ve trusted for thousands of hours. For the pilots of Air France 447, the incorrect airspeed indications and confusing stall warning sounds that were caused by a failure of the pitot static system proved to be too much to handle.

Furthermore, the Airbus design reinforced ideas that counter everything a pilot is taught, Specifically, these pilots learned that pulling the stick full aft would not result in a stall when the airplane was operating under a condition known as “normal law.” Much of their careers had been flown in airplanes with this feature. That night, after the initial climb, they were operating under “alternate law” which allowed far greater changes to the flight envelope, and removed that protection.

I wouldn’t have wanted to be in their shoes.

Much of the focus of the accident in the press has been to blame the pilots for clearly stalling the plane. One strange headline read “Baby pilot at the controls of AF 447.“

The ‘baby pilot’ was actually 32 years-old and had previously flown an A320 for 4 years and the A330/340 for just over a year. He had 2,936 hours of flight time with 807 hours in the A330/340.

The other copilot, at age 37 had 6,547 hours with 4,479 of them in the A330/340. Sadly, his wife was also on board the aircraft as a passenger.

And the 58 year-old captain, who came to the cockpit from his break halfway through the event had 11,000 hours of which 1,747 were in the A330/340.

I’ve said it before; in the eyes of the media, pilots are either heroes or villains depending on the outcome of the flight. These pilots faced challenges few of us have ever come across. Given the mechanical failures that started the chain of events, there’s certainly plenty of blame to go around. Events like these have a profound impact on our training and help prevent future accidents. And at least that is something we can be thankful for.

In case you’re interested in even more details, AvHerald has an excellent summary of the BEA preliminary Air France 447 accident report.
