The icing event lasted 60 seconds. Ninety seconds after the Master Warning/Cavalrty Charge, the Captain came back to the flight deck. At that point, the aircraft was at its assigned altitude, the Angle of attack was forty degrees, and they were descending, rapidly.
"...What the Hell are you doing?..." So, Captain noticed the loss of control. erm, boy howdy.
There was no angle of attack indicator, and Captain evidently neglected to ascertain Bonin"s stick aft, to the stop.
A minute later, they were discussing whether they were Descending, or Ascending.
Three issues of design prevented them from recovery.
No angle of attack indicator.
No way to see stick inputs from PF.
This aircraft Stalls essentially without cues, it is benign in the STALL.
Return one of these deficiencies to the cockpit, and they do not crash.
Return two of them, and they do not STALL.
Return all three, and we would have nothing to write about.
And Air France would be out forty thousand dollars for the AoA instrument.
C'est la Vie.....
