AA.V.C — Landing Configuration Stall Prevention

Objective: To determine that the applicant exhibits satisfactory knowledge, risk management, and skills associated with stalls in the landing configuration.

Knowledge

The applicant demonstrates understanding of:

• AA.V.C.K1Aerodynamics associated with stalls in the landing configuration, to include the relationship between angle of attack, airspeed, load factor, power setting, aircraft weight and balance, aircraft attitude, and sideslip effects.
• AA.V.C.K2Stall characteristics (i.e., airplane design) and impending stall and full stall indications (i.e., how to recognize by sight, sound, or feel).
• AA.V.C.K3Factors and situations that can lead to a stall when configured for landing and actions that can be taken to prevent it.
• AA.V.C.K4Effects of autoflight, flight envelope protection in normal and degraded modes, and unexpected disconnects of the autopilot or autothrottle/autothrust, if applicable to the aircraft used for the evaluation.
• AA.V.C.K5Fundamentals of stall recovery.

Risk Management

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

• AA.V.C.R1Factors and situations that could lead to an inadvertent stall, spin, and loss of control during landing.
• AA.V.C.R2Range and limitations of stall warning indicators (e.g., aircraft buffet, stall horn, stick shaker, etc.).
• AA.V.C.R3Failure to recognize and recover at the stall warning.
• AA.V.C.R4Improper stall recovery procedure.
• AA.V.C.R5Secondary stalls, accelerated stalls, elevator trim stalls, and cross-control stalls.
• AA.V.C.R6Effect of environmental elements on aircraft performance while landing as it relates to stalls (e.g., turbulence, icing, microbursts, and high-density altitude).
• AA.V.C.R7Stalls at a low altitude.
• AA.V.C.R8Collision hazards, to include aircraft and terrain.
• AA.V.C.R9Distractions, loss of situational awareness, or improper task management.

Skills

The applicant demonstrates the ability to:

• AA.V.C.S1Clear the area and select an entry altitude that will allow the recovery to be completed no lower than 3,000 feet AGL (non-transport category airplanes) or 5,000 feet AGL (transport category airplanes).
• AA.V.C.S2When accomplished in an FSTD, the entry should be consistent with the expected operational environment for a stall when fully configured for landing with no minimum entry altitude defined.
• AA.V.C.S3Establish the landing configuration (i.e., lift/drag devices set and landing gear extended) and maintain coordinated flight in simulated or actual instrument conditions throughout the maneuver.
• AA.V.C.S4Either manually or with the autopilot engaged, smoothly adjust pitch attitude, bank angle (15°-30°), and power setting in accordance with evaluator’s instructions to an impending stall.
• AA.V.C.S5Acknowledge the cue(s) and promptly recover at the first indication of an impending stall (e.g., buffet, stall horn, stick shaker, etc.).
• AA.V.C.S6Execute a stall recovery in accordance with procedures set forth in the POH/AFM.
• AA.V.C.S7Retract the flaps or other lift/drag devices to the recommended setting, if applicable; retract the landing gear after a positive rate of climb is established, if applicable; and return to the desired flight path as specified by the evaluator
