Power-on Stalls
Lesson Plan

Introduction:

  • To determine that the applicant exhibits satisfactory knowledge, risk management, and skills associated with power-on stalls
  • Note: See Appendix 6: Safety of Flight and Appendix 7: Aircraft, Equipment, and Operational Requirements & Limitations
  • References: FAA-H-8083-2, FAA-H-8083-3; AC 61-67; POH/AFM

Attention:

  • Research a case study
  • Discuss how the initial conditions set conditions which developed into an incident/accident/mishap
  • Relate similar personal experience of the same type of incident/accident/mishap

Motivator:

  • Helps recognize the indications of an imminent or full stall during power-on situations with the landing gear down and to make prompt, positive, and effective recoveries with a minimum loss of altitude
  • Power-on stalls simulate a stall from normal takeoff and departure

  • Power-on Stalls:

    • To determine that the applicant exhibits satisfactory knowledge, risk management, and skills associated with power-on stalls
    • Note: See Appendix 7: Aircraft, Equipment, and Operational Requirements & Limitations
    • References: FAA-H-8083-2, FAA-H-8083-3; AC 61-67; POH/AFM

    Power-on Stall Knowledge:

    The applicant must demonstrate an understanding of:
    • PA.VII.B.K1:
      Aerodynamics 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.B.K2:
      Stall characteristics (i.e., airplane design) and impending stall and full stall indications (i.e., how to recognize by sight, sound, or feel)
    • PA.VII.B.K3:
      Factors and situations that can lead to a power-on stall and actions that can be taken to prevent it
    • PA.VII.B.K4:
      Fundamentals of stall recovery

    Power-on Stall Risk Management:

    The applicant demonstrates the ability to identify, assess and mitigate risks, encompassing:
    • PA.VII.B.R1:
      Factors and situations that could lead to an inadvertent power-on stall, spin, and loss of control
    • PA.VII.B.R2:
      Range and limitations of stall warning indicators (e.g., airplane buffet, stall horn, etc.)
    • PA.VII.B.R3:
      Failure to recognize and recover at the stall warning during normal operations
    • PA.VII.B.R4:
      Improper stall recovery procedure
    • PA.VII.B.R5:
      Secondary stalls, accelerated stalls, and cross-control stalls
    • PA.VII.B.R6:
      Effect of environmental elements on airplane performance related to power-on stalls (e.g., turbulence, microbursts, and high-density altitude)
    • PA.VII.B.R7:
      Collision hazards, to include aircraft, terrain, obstacles, and wires
    • PA.VII.B.R8:
      Distractions, loss of situational awareness, or improper task management.

    Power-on Stall Skills:

    The applicant demonstrates the ability to:
    • PA.VII.B.S1:
      Clear the area
    • PA.VII.B.S2:
      Select 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.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 will induce 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
    • PA.VII.C.S8:
      Execute a stall recovery in accordance with procedures set forth in the POH/AFM
    • PA.VII.C.S9:
      Configure the airplane as recommended by the manufacturer, and accelerate to Vx or Vy
    • PA.VII.C.S10:
      Return to the altitude, heading, and airspeed specified by the evaluator
