VII. Slow Flight and Stalls 46 Task D. Accelerated Stalls References FAA-H-8083-2, FAA-H-8083-3; AC 61-67; POH/AFM Objective To determine that the applicant exhibits satisfactory knowledge, risk management related to accelerated (power-on or power-off) stalls. Note: See Appendix 6: Safety of Flight and Appendix 7: Aircraft, Equipment, and Operational Requirements & Limitations. Knowledge The applicant demonstrates understanding of: CA.VII.D.K1 Aerodynamics associated with accelerated stalls in various aircraft configurations, to include the relationship between angle of attack, airspeed, load factor, power setting, aircraft weight and center of gravity, aircraft attitude, and yaw effects. CA.VII.D.K2 Stall characteristics (i.e., airplane design) and impending stall and full stall indications (i.e., how to recognize by sight, sound, or feel). CA.VII.D.K3 Factors and situations that can lead to an accelerated stall and actions that can be taken to prevent it. CA.VII.D.K4 Fundamentals of stall recovery. Risk Management The applicant demonstrates the ability to identify, assess and mitigate risks, encompassing: CA.VII.D.R1 Factors and situations that could lead to an inadvertent accelerated stall, spin, and loss of control. CA.VII.D.R2 Range and limitations of stall warning indicators (e.g., aircraft buffet, stall horn, etc.). CA.VII.D.R3 Failure to recognize and recover at the stall warning during normal operations. CA.VII.D.R4 Improper stall recovery procedure. CA.VII.D.R5 Secondary stalls, cross-control stalls, and spins. CA.VII.D.R6 Effect of environmental elements on aircraft performance related to accelerated stalls (e.g., turbulence, microbursts, and high density altitude). CA.VII.D.R7 Collision hazards, to include aircraft, terrain, obstacles, and wires. CA.VII.D.R8 Distractions, loss of situational awareness, and/or improper task management. Skills The applicant demonstrates the ability to: CA.VII.D.S1 Clear the area. CA.VII.D.S2 Select an entry altitude that will allow the Task to be completed no lower than 3,000 feet AGL. CA.VII.D.S3 Establish the configuration as specified by the evaluator. CA.VII.D.S4 Set power appropriate for the configuration, such that the airspeed does not exceed the maneuvering speed (V A ), flap extension speed (V FE ), landing gear extended speed (V LE ), and any other POH/AFM limitation. CA.VII.D.S5 Establish 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.S6 Acknowledge the cues and recover promptly at the first indication of an impending stall (e.g., aircraft buffet, stall horn, etc.). CA.VII.D.S7 Execute a stall recovery in accordance with procedures set forth in the POH/AFM. CA.VII.D.S8 Retract the flaps to the recommended setting, if applicable; retract the landing gear, if retractable, after a positive rate of climb is established. CA.VII.D.S9 Accelerate to V X or V Y speed before the final flap retraction; return to the altitude, heading, and airspeed specified by the evaluator.
