The fact is that the black boxes recorded this behavior. Can we be 100% certain that the copilot actually did this? My concern is that we're still trusting the output of a system that has proven to be suspect.
- raldi 14y agoOther than the airspeed sensors freezing up, I'm not aware of any other known malfunctions. What makes you say the system was "proven to be suspect"?
- jt2190 14y agoI'm quoting Wikipedia's summary of the Report: * The stall warning deactivates by design when the angle of attack measurements are considered invalid and this is the case when the airspeed drops below a certain limit. * In consequence, the stall warning stopped and came back on several times during the stall; in particular, it came on whenever the pilot pushed forward on the stick and then stopped when he pulled back; this may have confused the pilots. * Despite the fact that they were aware that altitude was declining rapidly, the pilots were unable to determine which instruments to trust: it may have appeared to them that all values were incoherent. Personally, I'm not sure whether to believe that the copilot simply made an amateur mistake .
- Coincoin 14y agoThe copilot mentions he pulled the stick all along in the cockpit recording about 30 seconds before crashing. EDIT: When the pilot realized the error, he tried to correct, but it was already too late.
