DONE 9G Commercial Flight Maneuvers - Accelerated Stalls

1. What is an accelerated stall? (FAA-H-8083-3)

Answer 0

Accelerated stalls are stalls that occur at higher indicated airspeeds and/or lower than anticipated pitch attitudes as a result of excessive loads being suddenly imposed on an aircraft during improperly executed steep turns, stall and spin recoveries, and pull-ups from steep dives.

2. What is the objective of performing an accelerated stall? (FAA-H-8083-3)

Answer 1

The objective of demonstrating accelerated stalls is not to develop competency in setting up the stall, but rather to learn how they may occur and to develop the ability to recognize such stalls immediately, and to take prompt, effective recovery action.

3. If an airplane is skidding towards the outside of a steep turn, which wing will stall first? (FAA-H-8083-3)

Answer 2

It will have a tendency to roll to the inside of the turn because the inside wing stalls first.

Question 3

4. What standards must you maintain when executing an accelerated stall? (FAA-H-8081-12)

Answer 3

a. Exhibit satisfactory knowledge of the elements related to accelerated (power on or power off) stalls.
b. Select an entry altitude that allows the task to be completed no lower than 3,000 feet AGL.
c. Establish the airplane in a steady flight condition, airspeed below VA, 20 knots above unaccelerated stall speed or the manufacturer’s recommendation.
d. Transition smoothly from the cruise attitude to the angle of bank of approximately 45° that will induce a stall.
e. Maintain coordinated turning flight, increasing elevator back pressure steadily and firmly to induce the stall.
f. Recognize and recover promptly at the “onset” (buffeting) stall condition.
g. Return to the altitude, heading, and airspeed specified by the examiner.
