FAA Ground School Practice Test

What is the primary response required after a power failure during flight?

1. Immediately contact air traffic control

2. Establish the proper gliding attitude and airspeed

3. Attempt to restart the engine

4. Change altitude to regain control

The correct answer is: Establish the proper gliding attitude and airspeed

The primary response required after a power failure during flight is to establish the proper gliding attitude and airspeed. This step is critical for maintaining control of the aircraft and maximizing the distance you can glide toward a safe landing area. In a situation where the engine has failed, the pilot must convert the aircraft from powered flight to unpowered flight, which involves ensuring the aircraft is in an optimal position to maintain lift and control. By achieving the correct gliding attitude, the pilot minimizes drag and optimizes the aerodynamic efficiency of the aircraft, allowing it to cover more distance. Additionally, maintaining the appropriate airspeed is essential for controlling the aircraft; too slow could cause a stall, while too fast may make it difficult to manage the descent and control the aircraft during the landing phase. Managing the glide effectively also provides the pilot with time to evaluate possible landing options and make decisions regarding landing sites, which is crucial in an emergency situation. While contacting air traffic control, attempting to restart the engine, or changing altitude may be considerations in certain situations, the immediate and essential action following a power failure is to stabilize the aircraft in a glide to ensure safety and control.
