ACS AA.VII.C
Powerplant Failure (Simulated) (ASEL, ASES)
Knowledge
Immediate action items and emergency procedures for a forced landing.
Airspeed, including:
a. Importance of best glide speed and its relationship to distance
b. Difference between best glide speed and minimum sink speed
c. Effects of wind on glide distance
Effects of atmospheric conditions on emergency approach and landing.
A stabilized approach, including energy management concepts.
Emergency Locator Transmitters (ELTs) and other emergency locating devices.
Air traffic control (ATC) services to aircraft in distress.
Risk Management
Altitude, wind, terrain, obstructions, gliding distance, and available landing distance considerations.
Following or changing the planned flightpath to the selected landing area.
Collision hazards.
Configuring the airplane.
Low altitude maneuvering, including stall, spin, or controlled flight into terrain (CFIT).
Distractions, task prioritization, loss of situational awareness, or disorientation.
A powerplant failure in Instrument Meteorological Conditions (IMC).
Skill
Recognize the powerplant failure.
Determine the cause for the simulated powerplant failure (if altitude permits) and if a restart is a viable option.
Maintain positive control throughout the maneuver.
Establish and maintain the recommended best glide airspeed, ±5 knots. 52
Configure the airplane in accordance with the Pilot's Operating Handbook (POH)\Airplane Flight Manual (AFM) and existing conditions.
Select a suitable landing area considering altitude, wind, terrain, obstructions, and available glide distance.
Establish a proper flight path to the selected landing area.
Complete emergency checklist items appropriate to the airplane in a timely manner and as recommended by the manufacturer or operator.
Communicate with air traffic control (ATC) and the evaluator, as appropriate for the situation.
