Power-On Stalls

The applicant demonstrates understanding of:

• PA.VII.C.K1Aerodynamics 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.K2Stall characteristics as they relate to airplane design, and recognition impending stall and full stall indications using 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.

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

• 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., aircraft buffet, stall horn, etc.).
• PA.VII.C.R3Stall warning(s) during normal operations.
• PA.VII.C.R4Stall 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.
• PA.VII.C.R8Distractions, task prioritization, loss of situational awareness, or disorientation.

The applicant exhibits the skill to:

• PA.VII.C.S1Clear the area.
• PA.VII.C.S2Select 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.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 power.
• PA.VII.C.S5Transition smoothly from the takeoff or departure attitude to the pitch attitude that induces 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 Pilot's Operating Handbook (POH)/Flight Manual (FM).
• PA.VII.C.S9Configure 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.S10Return to the altitude, heading, and airspeed specified by the evaluator.
• PA.VII.C.S11Use single-pilot resource management (SRM) or crew resource management (CRM), as appropriate.
