IMO this is what they are gonna find.
The stall:
When an aircraft slows to below its stall speed, it is unable to generate enough lift in order to cancel out the forces that act on the aircraft .. as weight This will cause the aircraft to drop in altitude. The drop in altitude may cause the pilot to increase the angle of attack (the pilot pulls on the stick), because
normally increasing the angle of attack (pulling up) puts the aircraft in a climb. When the wing however exceeds its critical angle of attack, an increase in angle of attack (pulling up) will lead to a
loss of lift and a further loss of airspeed (the wing "
stalls"). The reason why the wing "stalls" ,,,, airflow over the top of the wing
separates....
, as the airplane falls, it could gain speed and then
structural failure could occur, typically due to excessive
g forces during the pullout phase of the recovery.
This is what happened to AIr France same kinda thing: To make up for low speed, a pilot will raise the nose of the aircraft to increase angle of attack, increase
Lift Coefficient and keep the same lift. However,
after a critical angle of attack is passed (often around 16 degrees) the lift stops increasing and actually collapses, causing a stall.
So the speedmmeter was telling em there speed wrong, so he repsonded, its so easy to say pilot error without taking in the variables!
