Objective: To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with power-on stalls. Note: See Appendix 2: Safety of Flight and Appendix 3: Aircraft, Equipment, and Operational Requirements & Limitations for information related to this Task.

Knowledge — The applicant demonstrates understanding of:

PA.VII.C.K1 Aerodynamics associated with stalls in various airplane configurations, including the relationship between angle of attack, airspeed, load factor, power setting, airplane weight and center of gravity, airplane attitude, and yaw effects.

PA.VII.C.K2 Stall characteristics as they relate to airplane design, and recognition impending stall and full stall indications using sight, sound, or feel.

PA.VII.C.K3 Factors and situations that can lead to a power-on stall and actions that can be taken to prevent it.

PA.VII.C.K4 Fundamentals of stall recovery.

Risk Management — The applicant is able to identify, assess, and mitigate risk associated with:

PA.VII.C.R1 Factors and situations that could lead to an inadvertent power-on stall, spin, and loss of control.

PA.VII.C.R2 Range and limitations of stall warning indicators (e.g., aircraft buffet, stall horn, etc.).

PA.VII.C.R3 Stall warning(s) during normal operations.

PA.VII.C.R4 Stall recovery procedure.

PA.VII.C.R5 Secondary stalls, accelerated stalls, elevator trim stalls, and cross-control stalls.

PA.VII.C.R6 Effect of environmental elements on airplane performance related to power-on stalls (e.g., turbulence, microbursts, and high-density altitude).

PA.VII.C.R7 Collision hazards.

PA.VII.C.R8 Distractions, task prioritization, loss of situational awareness, or disorientation.

Skills — The applicant exhibits the skill to:

PA.VII.C.S1 Clear the area.

PA.VII.C.S2 Select an entry altitude that allows the Task to be completed no lower than 1,500 feet above ground level (AGL) (ASEL, ASES) or 3,000 feet AGL (AMEL, AMES).

PA.VII.C.S3 Establish the takeoff, departure, or cruise configuration, as specified by the evaluator, and maintain coordinated flight throughout the maneuver.

PA.VII.C.S4 Set power (as assigned by the evaluator) to no less than 65 percent power.

PA.VII.C.S5 Transition smoothly from the takeoff or departure attitude to the pitch attitude that induces a stall.

PA.VII.C.S6 Maintain a specified heading, ±10° if in straight flight; maintain a specified angle of bank not to exceed 20°, ±10° if in turning flight, while inducing the stall.

PA.VII.C.S7 Acknowledge cues of the impending stall and then recover promptly after a full stall occurs. Private Pilot for Airplane Category ACS (FAA-S-ACS-6C) 45

PA.VII.C.S8 Execute a stall recovery in accordance with procedures set forth in the Pilot's Operating Handbook (POH)/Flight Manual (FM).

PA.VII.C.S9 Configure the airplane as recommended by the manufacturer, and accelerate to best angle of climb speed (VX) or best rate of climb speed (VY).

PA.VII.C.S10 Return to the altitude, heading, and airspeed specified by the evaluator.

PA.VII.C.S11 Use single-pilot resource management (SRM) or crew resource management (CRM), as appropriate.
