Power-Off Stalls
Lesson Plan

Introduction:

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

Attention:

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

Motivator:

  • Power-off stalls simulate a stall during the normal approach to landing
    • Should be set up in the landing configuration
  • Recoveries therefore train a pilot to make prompt, positive, and effective recoveries with a minimum loss of altitude
  • This stall may occur while descending in an actual or simulated emergency or in any power-off situation when airspeed is not controlled

Power-Off Stall Knowledge:

The applicant demonstrates 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-off stall and actions that can be taken to prevent it
  • PA.VII.B.K4:

    Fundamentals of stall recovery

Power-Off Risk Management:

The applicant is able to identify, assess, and mitigate risk associated with:
  • PA.VII.B.R1:

    Factors and situations that could lead to an inadvertent power-off 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-off 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, task prioritization, loss of situational awareness, or disorientation

Power-Off Stalls Skills:

The applicant exhibits the skill 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.B.S3:

    Configure the airplane in the approach or landing configuration, as specified by the evaluator, and maintain coordinated flight throughout the maneuver
  • PA.VII.B.S4:

    Establish a stabilized descent
  • PA.VII.B.S5:

    Transition smoothly from the approach or landing attitude to a pitch attitude that will induce a stall
  • PA.VII.B.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.B.S7:

    Acknowledge cues of the impending stall and then recover promptly after a full stall occurs
  • PA.VII.B.S8:

    Execute a stall recovery in accordance with procedures set forth in the POH/AFM
  • PA.VII.B.S9:

    Configure the airplane as recommended by the manufacturer, and accelerate to Vx or Vy
  • PA.VII.B.S10:

    Return to the altitude, heading, and airspeed specified by the evaluator
