Aerodynamics of cross-controlled stalls.

Flight situations where unintentional cross-controlled stalls may occur. 71

Recognition of cross-controlled stalls.

Entry procedure and minimum entry altitude.

Recovery procedure.

Common errors related to this Task.

Stall recovery procedure.

Effect of environmental elements on airplane performance related to cross-controlled stalls (e.g., turbulence, microbursts, and high-density altitude).

Collision hazards.

Aircraft limitations.

Distractions, task prioritization, loss of situational awareness, or disorientation.

Clear the area.

Select an entry altitude that allows the Task to be completed no lower than 3,000 feet above ground level (AGL).

Configure the airplane (with gear down) and close the throttle.

Establish a normal glide airspeed and trim the airplane.

Roll into a medium-banked turn, apply excess rudder in the turn while holding bank constant with opposite aileron input, and add elevator pressure to keep the nose from lowering.

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.

Describe and demonstrate conditions that lead to a cross-controlled stall for future avoidance.
