Stall Flashcards
Autopilot may mask heavy or asymmetric control forces in case of:
Icing.
AOM I 4.12.1
The lift force generated on a surface is a result of
its angle of attack (AOA), the dynamic pressure of the air moving around it, which is a function of the airspeed and air density, and the size and shape of the surface. As the AOA increases, lift increases proportionally.
AOM I 4.12.1
the angle of attack is the angle between
the relative wind and the chord line of the airfoil
AOM I 4.12.1
The emphasis of the stall recovery maneuver is
to effectively reduce the AOA by putting the airplane in a nose down attitude.
AOM I 4.12.1
If terrain contact is NOT a factor, the PF must disengage the autothrottle and simultaneously reduce
the AOA by pushing the control column to apply nose down, level the wings and adjust the thrust as required. The PM must confirm autopilot and autothrottle disengaged and monitor the altitude and speed of the airplane.
AOM I 4.12.1
If Terrain Contact is a Factor - At the first indication of a stall (buffet or stick shaker),
disconnect the autopilot, advance the thrust levers to MAX thrust while leveling the wings. Control pitch as smoothly as possible. As the engines accelerate, the aircraft nose will pitch up. To assist in pitch control, add more nose down trim as the thrust increases.
