Skill
Clear the area.
Select an entry altitude that allows the Task to be completed no lower than 3,000 feet above ground level (AGL).
Retard the throttle and configure the airplane for landing.
Establish a normal glide airspeed and trim the airplane.
Advance the throttle to the maximum allowable power as in a go-around.
Acknowledge the cues at the first indication of a stall (e.g., aircraft buffet, stall horn, etc.).
Recover at the first indication of a stall or after a full stall has occurred, as specified by the evaluator.
Adjust trim and return to the desired flightpath.
Describe and demonstrate conditions that lead to an elevator trim stall for future avoidance.
Analyze and correct common errors related to this Task.
