First, remember the Breaking News Consumer's Handbook: Airline Edition ( https://media2.wnyc.org/i/620/620/l/80/1/BNCHAE.jpg ). Second, I'm sure that Mr. Robin is a nice guy, but there's no need to publish his stray speculations just two days after the crash.

FlightRadar24 has copies of the ADS-B data. It looks very much like the auto-pilot was deliberately set to an altitude of 96 feet.

Earlier quoted context omitted.

The co-pilot was breathing normally for ten minutes while the door was being hammered repeatedly. Interpreting this as 'deliberate' inaction is hardly 'stray speculation'.

Isn't that a little bit off he didn't mutter any words after seizing the opportunity of his co-worker's unplanned leaving of the cockpit ?

Why would that be a little off? Not everyone mutters to an empty room.

These doors very effectively mean that control of the plane would be put into the hands of the cabin crew, but magnifies the cost of a rogue operator -- I am certain the risks were evaluated and the challenge of a determined suicidal pilot was ruled outside scope. And yes, there are emergency override codes, but there are also time override-overrides from within the cabin. Even if the protocol where two members of st…

You also have to ask whether a lack of the door lock would have prevented the crash. Can a rogue pilot crash the plane fast enough that the door locks are irrelevant? Can he crash it while the other pilot is in the cockpit? I remember other black box recordings from another crash where one pilot was merely confused , steering the plane into a crash while the others tried to save it, and no one realized what was going…

That was the Air France flight, and it strikes me as a major UX disaster. The flight sticks' input was averaged, as if that's ever a desirable scenario!

"Oh yeah, we know we want to keep it level, so you pull back on the stick a bit, I'll push it an equal amount and we'll be okay." Yeeeah.

It seems pretty far from stray speculations. It is assumed after a check of the black box. That is ultimately what we rely on for an after the fact analysis. If we can't use that what do we use? And you want to wait a year to find out what happened to your loved ones?

> And you want to wait a year to find out what happened to your loved ones? "Your loved ones" died in an aircraft crash. They why of it matters less, and can wait for an accurate answer instead of rampant speculation. As for the year time frame, it really can take up to a year to figure out. As you say, they're working from an incomplete puzzle. Perhaps the black box does say XYZ, but is that the whole story? They ad…

The article specifically states the the recorder indicates the copilot dialed in a deliberate descent.

I may be mistaken but I believe airline cockpits were made to be able to lock out people from entering in the event of a terrorist activity to take over the plane. This was initiated after 9/11.

That is true. What I'm wondering about is why the plane allows a pilot to take a fatal action. For example, why would an auto-pilot system allow a jetliner to nose dive? Maybe it does not. I'm certain these scenarios have been considered, and I'm sure the developers had very solid reasons as to why something like this doesn't exist (if it actually does not). I'm curious if the plane has enough input to determine "if…

Nobody considered a terrorist suicide by flying the plane into a building until it happened. So they made the doors lockable so that nothing passengers did could get them into the cockpit.

During that they obviously didn't think that any pilot would suicide the plane by flying it into the ground.

All the while there is value in driving planes into the ground, it's an unwinnable solution.

Is it realistic that we see human controls largely removed from passenger plane pilots? Or ground-based group overrides? I know that for the largest jets, pilots already operate within some sort of computer-decided 'envelope' (I think it's called) of reasonable decisions. I think we will see personal driving banned in some cities (CBDs at least) or routes in the coming decades as self-driving cars come to dominate ou…

I'd suspect the risks of a ground-control system would be substantially higher than the chance of a pilot deliberately crashing a plane every decade or so.

Does anyone know if there are any authorization levels implemented in airplane software ? If Pilot had a root pass for the door lock, this could have ended up differently. My sincerest condolences to families of passengers..

Only unless pilot/co-pilot roles were the same. If it were the pilot trying to crash the plane - there’d still be a problem

The issue with that is that the pilot can be tortured/blackmailed until they give up the password/code.

The point with the designs now is that once they are locked, they stay locked, and no amount of killing hostages gets it opened.

Germanwings did not have a policy of requiring a second person in the cockpit in situations where the captain leaves the cockpit. I imagine this is going to become fault standard in aviation from now on.

I wonder how much that would have helped in this case though. Someone determined to crash a plane would not have too much of a problem incapacitating any cabin crew member (by surprise most likely) before his attempt. I believe that having a second person in the cockpit is more useful (and seemingly essential) if the Pilot/Co-Pilot loses conciousness in order for the door to still be opened.

My initial reaction to this is the fact that the co-pilot didn't attempt to seize the plane from the pilot or other crew, but only took advantage of an opportunity.

In this specific case, it may be possible that the co-pilot would not have forced the situation where he was in sole control of the plane.

The emotional side of me wants to call the man a coward, and a coward wouldn't be openly aggressive towards a flight attendant, but that's not a very productive point of view. In future cases, there's just no reason why a future murderous co-pilot couldn't be more aggressive, so it's still a situation worth considering.

Can someone with aviation experience share how often pilots receive psychological evaluation? I just asked a friend who used to be a pilot for Ryan Air and he said he had never received one.

From my memory of taking my 3rd class medical its trust based, if you don't have a written record in your med file of mental problems or tell the doc you have problems then there's no way for them to know.

Also from memory a 1st class was pretty much a 3rd class with stricter limits and an electrocardiogram which is why it costs microscopically more. At least in the old days if you got a 1st after it expired, it acted like a 2nd for the remainder of the year, and a 3rd for the next year, but a 1st cost more, so I didn't bother (not expecting to achieve ATP cert within 6 months of my solo LOL)

Crudely and inexactly but more or less true, you need a valid 3rd to be a general aviation pilot, a valid 2nd to haul cargo or be a bush pilot, and a valid 1st to work for an airline. Things will be slightly different in Germany but less different than you'd think... we have trust agreements to allow them to fly here and us to fly there so things are vaguely similar but it doesn't matter if my details are slightly off.

Finally you have to be realistic. If 25% of the population experiences a mental health issue at some point in their life or whatever ridiculously high percentage, then given the huge fraction of the population flying with issues, issues obviously almost never cause a problem, its right up there with meteor strikes. So you end up with false positive/negative issues. If you assume all men have been dumped by a girlfriend at least once that means roughly 3e9 false positive if you assume all dumped dudes are going to mass murder an entire airplane, a false positive rate of eight nines I think? That idea would be up there with banning German pilots, after all one of them apparently did kill a lot of people and the false postive rate is staggeringly lower than banning all people with mere claustrophobia or a bad attitude or whatever.
