PA.VII.C — Power-On Stalls

Objective: To determine that the applicant exhibits satisfactory knowledge, risk management, and skills associated with power-on stalls.

Knowledge

The applicant demonstrates understanding of:

• PA.VII.C.K1Aerodynamics associated with 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.
• PA.VII.C.K2Stall characteristics (i.e., airplane design) and impending stall and full stall indications (i.e., how to recognize by sight, sound, or feel).
• PA.VII.C.K3Factors and situations that can lead to a power-on stall and actions that can be taken to prevent it.
• PA.VII.C.K4Fundamentals of stall recovery.

Risk Management

The applicant demonstrates the ability to identify, assess and mitigate risks, encompassing:

• PA.VII.C.R1Factors and situations that could lead to an inadvertent power-on stall, spin, and loss of control.
• PA.VII.C.R2Range and limitations of stall warning indicators (e.g., airplane buffet, stall horn, etc.).
• PA.VII.C.R3Failure to recognize and recover at the stall warning during normal operations.
• PA.VII.C.R4Improper stall recovery procedure.
• PA.VII.C.R5Secondary stalls, accelerated stalls, elevator trim stalls, and cross-control stalls.
• PA.VII.C.R6Effect of environmental elements on airplane performance related to power-on stalls (e.g., turbulence, microbursts, and high-density altitude).
• PA.VII.C.R7Collision hazards, to include aircraft, terrain, obstacles, and wires.
• PA.VII.C.R8Distractions, loss of situational awareness, and/or improper task management.

Skills

The applicant demonstrates the ability to:

• PA.VII.C.S1Clear the area.
• PA.VII.C.S2Select an entry altitude that will allow the Task to be completed no lower than 1,500 feet AGL (ASEL, ASES) or 3,000 feet AGL (AMEL, AMES).
• PA.VII.C.S3Establish the takeoff, departure, or cruise configuration, as specified by the evaluator, and maintain coordinated flight throughout the maneuver.
• PA.VII.C.S4Set power (as assigned by the evaluator) to no less than 65 percent available power.
• PA.VII.C.S5Transition smoothly from the takeoff or departure attitude to the pitch attitude that will induce a stall.
• PA.VII.C.S6Maintain 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.S7Acknowledge cues of the impending stall and then recover promptly after a full stall occurs.
• PA.VII.C.S8Execute a stall recovery in accordance with procedures set forth in the POH/AFM.
• PA.VII.C.S9Configure the airplane as recommended by the manufacturer, and accelerate to VX or VY
• PA.VII.C.S10Return to the altitude, heading, and airspeed specified by the evaluator.
