COMM.VII.D — Accelerated Stalls
Objective: To determine that the applicant exhibits satisfactory knowledge, risk management related to accelerated (power-on or power-off) stalls.
Knowledge
The applicant demonstrates understanding of:
CA.VII.D.K1Aerodynamics associated with accelerated stalls in various airplane configurations, to include the relationship between angle of attack, airspeed, load factor, power setting, airplane weight and center of gravity, airplane attitude, and yaw effects.CA.VII.D.K2Stall characteristics (i.e., airplane design), impending stall, and full stall indications (i.e., how to recognize by sight, sound, or feel).CA.VII.D.K3Factors and situations that can lead to an accelerated stall and actions that can be taken to prevent it.CA.VII.D.K4Fundamentals of stall recovery.
Risk Management
The applicant demonstrates the ability to identify, assess and mitigate risks, encompassing:
CA.VII.D.R1Factors and situations that could lead to an inadvertent accelerated stall, spin, and loss of control.CA.VII.D.R2Range and limitations of stall warning indicators (e.g., airplane buffet, stall horn, etc.).CA.VII.D.R4Improper stall recovery procedure.CA.VII.D.R5Secondary stalls, cross-control stalls, and spins.CA.VII.D.R6Effect of environmental elements on airplane performance related to accelerated stalls (e.g., turbulence, microbursts, and high-density altitude).CA.VII.D.R7Collision hazards, to include aircraft, terrain, obstacles, and wires.CA.VII.D.R8Distractions, improper task management, loss of situational awareness, or disorientation.
Skills
The applicant demonstrates the ability to:
CA.VII.D.S1Clear the area.CA.VII.D.S2Select an entry altitude that will allow the Task to be completed no lower than 3,000 feet AGL.CA.VII.D.S3Establish the configuration as specified by the evaluator.CA.VII.D.S4Set power appropriate for the configuration, such that the airspeed does not exceed the maneuvering speed (VA) or any other applicable POH/AFM limitation.CA.VII.D.S5Establish and maintain a coordinated turn in a 45° bank, increasing elevator back pressure smoothly and firmly until an impending stall is reached.CA.VII.D.S6Acknowledge the cue(s) and recover promptly at the first indication of an impending stall (e.g., aircraft buffet, stall horn, etc.).CA.VII.D.S7Execute a stall recovery in accordance with procedures set forth in the POH/AFM.CA.VII.D.S8Configure the airplane as recommended by the manufacturer, and accelerate to VX or VY.CA.VII.D.S9Return to the altitude, heading, and airspeed specified by the evaluator.
