How many of you know what EMAS is? I can guarantee that the 34 people on a US Airways Express jet in Charleston West Virginia now are intimately familiar with it. It prevented them from plunging off a mountain. This mountain. Seriously.

EMAS on Charleston Runway

EMAS stands for Engineered Material Arresting System – a name only the government could love. Think of it like a runaway truck ramp. You know what I’m talking about. When you’re coming down a mountain and you see those gravel strips on the side where trucks can go if their brakes fail? (For those of you in the Midwest, a mountain is something you’ve probably seen on TV.) But EMAS stops airplanes, not trucks, so it requires some more strength.

You will find an EMAS in 28 airports today; the first was installed at JFK in 1996. How do they pick the airports? Airports in the US are required to have overruns called runway safety areas (RSA) that are 1,000 feet long and 500 feet wide, at least. (Many advocate for more.) There’s only one problem. Many airports were built before these rules went into place, so they don’t have the room. Those airports have been getting EMAS.

Remember the Southwest flight the went off the runway and parked at a gas station in Burbank in 2000? By 2002, Burbank had an EMAS. And that brings us to our buddies at Charleston, West Virginia, better known by many as Charlie West. Charlie West sits on a mountain (as you saw above), and in 2007, the feds decided it might be a good idea to keep planes from sliding off the end. Good thing they did.

Earlier this week, a US Airways Express 50 seat regional jet operated by wholly-owned PSA Airlines rejected its takeoff. It couldn’t stop quickly enough and it ended up off the runway. Thanks to EMAS, the plane didn’t plunge off the end of the runway. Brian Belcher and the rest of the team at Charlie West have been doing an excellent job of keeping people up to date via Twitter and Facebook. (I wrote about Charleston’s expert use of social media on BNET.) They posted this picture:

CRW PSA Overrun

Holy crap. Now, the plane has been moved, the airport is back to normal operations, and all they need to do now is fix the EMAS so it can do its job once again. Talk about a great invention.

I don’t like to dwell on these end-of-year facts and figures too often, but sometimes I think it’s worth pausing to take a look. For example, let’s take a look at airline safety in 2009. It was actually a very safe year. There were 30 fatal “airliner” accidents that ended with 758 people being killed (1 on the ground). That sounds like a lot, right? We’ll break it down further after this slideshow from Aviation Safety Network, which highlights the accidents of the year.

So, of those 30 accidents (which may seem like a huge number), only 11 involved passenger flights. And of those, many were in the usual places you would expect – the ones without a strong safety leadership culture. There was one in Rwanda, one in Papua New Guinea, and one in Indonesia. I believe having at least one accident is required in Indonesia every year. There was an old TU-154 that crashed in Iran and a little Embraer 110 that went down in the Amazon. There was also that Yemenia A310 that crashed in the Indian Ocean off Africa.

Some accidents involved runway overruns and were mostly survivable. The Turkish 737 that landed hard in Amsterdam is one example, as was the Bangkok Airways ATR-72 and the Mashad IL-62. But that brings us to the big two.

The biggest, of course, was the Air France flight that plunged into the Atlantic off the coast of Brazil. We still don’t know what caused that one, and we may very well never know.

The other? The Colgan Air (Continental Connection) Dash-8 that went down in Buffalo. That, of course, was caused by a combination of pilot error, fatigue, and bad weather.

So when it comes right down to it, 2009 was a very safe year. You were much safer flying than, well, eating airline food, especially if it was prepared by LSG SkyChefs in Denver. (That’s a whole different, disgusting story.)

It has been plastered all over the news, but I wanted to wait a little until we had more information on what happened. Now that the NTSB has released its early findings, let’s talk. This is a mess.

You know the story – Northwest 188 from San Diego to Minneapolis decided that Wisconsin was a better destination. Once pilots realized they had gone too far east, they turned around and landed. As far as I’m concerned, the excuses NW 188 via FlightAwaregiven by the pilots seem flimsy at best.

At left, you can see what happened to flight 188 on October 21 thanks to FlightAware. The last radio communication is said to have occurred around 656p Central Time. That would have been about 20 minutes after they started talking to Denver Center (the air traffic control center that controls that patch of airspace). The plane was at 37,000 feet traveling at a roughly 30 degree heading.

There were a couple of slight course corrections but nothing else until 814p when they got back in touch with air traffic control, well past Minneapolis. They then started turning south and at 817p they started descending. Air traffic control made them do some turns to prove they hadn’t been hijacked, and they ended up landing around 9p. So what the heck happened?

Well, these pilots had ample experience, haven’t had any problems before, and weren’t fatigued after a 19 hour layover in San Diego. The pilots insist they weren’t arguing nor sleeping but rather having a heated discussion. That means that for over and hour, the pilots ignored radio calls and attempted contact from their company dispatcher because they were engrossed in this conversation about their new crew scheduling system.

At one point, the pilots pulled out their laptops, apparently to review the new system. Delta says they don’t allow personal laptop use for pilots while flying, so naturally the mainstream media folks have jumped on this as the headline. It shouldn’t be. But could the Laptop for NW Pilotsnew bidding system really have been so exciting to have kept them distracted for over an hour? It’s certainly going to be a complicated topic of discussion, but I find it unconscionable that they would simply forget that they were flying an airplane for that long.

Delta put out a statement on personal laptop use that says:

Using laptops or engaging in activity unrelated to the pilots’ command of the aircraft during flight is strictly against the airline’s flight deck policies and violations of that policy will result in termination.

Sounds like these guys are going to have to fight for their jobs.

I still just can’t believe that for over an hour they failed to respond to any attempts at communication. You could have a live stage show in the cockpit and they still should have heard something to trigger them to actually pay attention for a minute. What did finally bring them back to reality? A flight attendant called up 5 minutes before they were supposed to arrive asking for an estimated time of arrival. That’s when they realized they screwed up.

Even though they were out of contact for over an hour, they didn’t overshoot the airport by that much. The flight the day before was 3:36 while the one the day after was 3:20. This flight took 3:54. I have to assume that had it gone any longer, some sort of fuel warning would have caught their attention . . . or not.

Sadly, we’ll probably never know what happened since the cockpit voice recorder only held 30 minutes of data. It began during final approach, so all the good stuff was missed. We probably won’t know if something else happened instead.

I can’t say this makes me particularly nervous about flying in general, but it definitely makes me think twice about those reinforced cockpit doors. What if these guys had been so engrossed that they failed to answer to any sort of communication attempts? Or what if they both ate the fish? Ted Striker never would have been able to get up there to save the day.

Though the ultimate reason for the Air France A330 crash in the South Atlantic will likely never be known for sure, the European Aviation Safety Agency (EASA) has recently issued an urgent Airworthiness Directive to replace certain Thales-manufactured pitot tubes on A330/A340 airplanes. A pitot tube problem is one of the possible explanations for that Air France crash.

For those Airbus Near the Pitot Tubewho don’t know, a pitot tube is a goofy little thing that sticks out from the aircraft into the air. You can see a great example of one at left. These little guys use pressure measurement to determine airspeed. One of the theories regarding the Air France accident is that the pitot tube incorrectly measured airspeed and that triggered all kinds of problems that ultimately led to the accident.

Now, EASA is saying that any A330/A340 aircraft with the Thales pitot tubes need to be changed (and the FAA has followed as well). There are apparently two different types of Thales pitot tubes. The “AA” version must be replaced no matter what. The “BA” version is ok in one place, but the other two places must have Goodrich ones involved.

So what exactly is the problem? According to EASA:

Occurrences have been reported on the A330/A340 family aeroplanes of airspeed indication discrepancies while flying at high altitudes in inclement weather conditions.

The Thales AA pitots have “a greater susceptibility to adverse environmental conditions” than the Goodrich ones. The Thales BA pitots are better, but “it has not yet demonstrated the same level of robustness to withstand high-altitude ice crystals as the Goodrich . . . probe.”

While they say that they haven’t actually found any safety issue and that this is a precautionary measure, the fact that these all need to be replaced within 4 months certainly makes it seem somewhat rushed.

By the way, Air France had Thales pitot tubes, but they’ve already made these changes. Delta has also already made the changes to their A330s. Both US Airways and Lufthansa have always had Goodrich.
