Could the thrust and pitch have resulted from following a procedure?
Passenger here with a question for the professionals.
The BEA report notes that TOGA thrust and pitch up were selected at least some of the time.
Is it at all possible that this could have resulted from following an Unreliable Airspeed or Stall Warning Procedure that turned out not to be optimal for the circumstances?
I ask because there appear to be several different power and pitch recommendations depending on the phase of flight in which the problem occurs. For example, the unreliable airspeed procedure recommends TOGA and 15 degrees if the problem occurs before reducing thrust, but lower thrust and pitch at higher altitudes.
I am in no way trying to place blame here. I am certain many factors will prove to be involved. I ask because some have suggested that the procedures were confusing and wondered whether they could have led the crew astray. For example, was it clear whether a stall warning should be respected (and that procedure followed) or not?
