Area of Operation IX
Slow Flight and Stalls
3 Tasks
Task A Maneuvering During Slow Flight (Wing-Borne Configuration)
References
FAA-H-8083-2, FAA-H-8083-25; Flight Manual
Objective
To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with maneuvering during slow flight in wing-borne configuration.
Note
See Appendix 2: Safety of Flight and Appendix 3: Aircraft, Equipment, and Operational Requirements & Limitations for information related to this Task.
Knowledge
Aerodynamics associated with slow flight in various aircraft configurations, including the relationship between angle of attack, airspeed, load factor, power setting, aircraft weight and center of gravity, aircraft attitude, and yaw effects.
Risk Management
Inadvertent slow flight and flight with a stall warning, which could lead to loss of control.
Range and limitations of stall warning indicators (e.g., aircraft buffet, stall horn, etc.).
Uncoordinated flight.
Effect of environmental elements on aircraft performance (e.g., turbulence, microbursts, and high density altitude).
Collision hazards.
Distractions, task prioritization, loss of situational awareness, or disorientation.
Skills
Clear the area.
Select an entry altitude that allows the Task to be completed no lower than 3,000 feet above ground level (AGL).
Establish and maintain an airspeed at which any further increase in angle of attack, increase in load factor, or reduction in power, would result in a stall warning (e.g., aircraft buffet, stall horn, etc.).
Accomplish coordinated straight-and-level flight, turns, climbs, and descents with the aircraft configured as specified by the evaluator without a stall warning (e.g., aircraft buffet, stall horn, etc.).
Maintain the specified altitude, ±100 feet; specified heading, ±10°; airspeed, +10/-0 knots; and specified angle of bank, ±10°.
Task B Power-Off Stalls
References
FAA-H-8083-2, FAA-H-8083-25; Flight Manual
Objective
To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with power-off stalls.
Note
See Appendix 2: Safety of Flight and Appendix 3: Aircraft, Equipment, and Operational Requirements & Limitations for information related to this Task.
Knowledge
Aerodynamics associated with stalls in various aircraft configurations, including the relationship between angle of attack, airspeed, load factor, power setting, aircraft weight and center of gravity, aircraft attitude, and yaw effects.
Stall characteristics as they relate to aircraft design, and recognition impending stall and full stall indications using sight, sound, or feel.
Factors and situations that can lead to a power-off stall and actions that can be taken to prevent it.
Fundamentals of stall recovery.
Risk Management
Factors and situations that could lead to an inadvertent power-off stall, spin, and loss of control.
Range and limitations of stall warning indicators (e.g., aircraft buffet, stall horn, etc.).
Stall warning(s) during normal operations.
Stall recovery procedure.
Secondary and accelerated stalls.
Effect of environmental elements on aircraft performance related to power-off stalls (e.g., turbulence, microbursts, and high-density altitude).
Collision hazards.
Distractions, task prioritization, loss of situational awareness, or disorientation.
Skills
Clear the area.
Select an entry altitude that allows the Task to be completed no lower than 3,000 feet AGL or as recommended by the manufacturer, whichever is higher.
Configure the aircraft in the approach or landing configuration, as specified by the evaluator, and maintain coordinated flight throughout the maneuver.
Establish a stabilized descent.
Transition smoothly from the approach or landing attitude to a pitch attitude that induces a stall.
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.
Acknowledge cues of the impending stall and then recover promptly after a full stall occurs.
Execute a stall recovery in accordance with procedures set forth in the Flight Manual.
Configure the aircraft as recommended by the manufacturer and accelerate to VX or VY.
Return to the altitude, heading, and airspeed specified by the evaluator.
Use single-pilot resource management (SRM) or crew resource management (CRM), as appropriate.
Task C Power-On Stalls
