Maneuvering During Slow Flight
Knowledge
Aerodynamics associated with slow flight 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.
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 airplane performance (e.g., turbulence, microbursts, and high- density altitude).
Collision hazards.
Distractions, task prioritization, loss of situational awareness, or disorientation.
Skill
Clear the area.
Select 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).
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, ±50 feet; specified heading, ±10°; airspeed, +5/-0 knots; and specified angle of bank, ±5°.
