> Even when it was a suicidal pilot flying the plane into a mountain on purpose. Someone had to supervise him (there are two crew members in the cockpit for a reason), someone gave him a medical, there is automation in the cockpit that could have at least caused an alarm, etc.
There was indeed a suicidal pilot that flew into a mountain, I'm not sure if you were deliberately referencing that specific time. In that case he was alone in the cabin – this would have happened briefly but he was able to lock the cabin door before anyone re-entered, and the lock cannot be opened by anyone from the other side in order to avoid September 11th-type situations. It only locks for a brief period but it can be reapplied from the pilot side before it expires an indefinite number of times.
I'm not saying that we can put that one down purely to human action, just that (to be pedantic) he wasn't being supervised by anyone, and there were already any number of alarms going off (and the frantic copilots on the other side of the door were well aware of them).
And as a result of that incident the procedures have changed, now a cabin crew member (or relief pilot in long haul ops) joins the other pilot in the cockpit if one has to go to the bathroom.
A similar procedure already exists for controlled rest in oceanic cruise flight at certain times, using the cabin crew to ensure the remaining pilot was checked to be awake every 20 minutes.
I was referring specifically to the Germanwings incident.
That pilot shouldn't have been in the cockpit to begin with - his eyesight was failing, he had mental problems (has been medically treated for suicidal tendencies), etc. This was not discovered nor identified, due to deficiencies in the system (doctors didn't have the duty to report this, he withheld the information from his employer, etc.)
The issue with the door was only the last element of the chain.
There were changes as the result of this incident - the cabin crew member has to be in the cockpit whenever one of the pilots steps out, there were changes to how the doors operate, etc.
The change to require a cabin crew member in the cockpit is a good one.
Not really sure what you can about the suicidal tendencies. If you make pilots report medical treatment for suicidal tendencies, they aren't going to seek treatment for suicidal tendencies.
That should have been reported by the doctor. Lubitz (the pilot) was denied an American license for this before - and somehow it wasn't caught/discovered when he got the Lufthansa/Germanwings job. Or nobody has followed up on it.
On the day of the crash he was not supposed to be on the plane at all - a paper from the doctors was found at his place after the crash declaring him unfit for duty. He kept it from his employer and it wasn't reported by the doctors neither (they didn't have the duty to do so), so the airline had no idea. Making a few of the holes in the cheese align nicely.
Pilots have the obligation to report when they are unfit for duty already, (no matter what the reason, being treated for a psychiatric problem certainly applies, though).
What was/is missing is the obligation of doctors to report such important issue to the employer when the crewman is unfit. It could be argued that it would be an invasion of privacy but there are precedents for this - e.g. failed medicals are routinely being reported to the authorities (not just for pilots - also for car drivers, gun holders, etc. where the corresponding licenses are then suspended), as are discoveries of e.g. child abuse.
