What is primarily tested during emergency engine-out drills?

During emergency engine-out drills, the primary focus is on flight control and stability. These drills are crucial for pilots to learn how to maintain control of the aircraft when one engine fails. The emphasis is on managing the aircraft's attitude, airspeed, and trajectory, which are all critical aspects of ensuring the safety of the flight under such an emergency scenario.

Pilots must be proficient in recognizing the signs of an engine failure and executing the appropriate procedures to maintain control of the aircraft. This involves using the remaining engine effectively to maintain altitude and direction while also managing the aircraft's response to the asymmetric thrust caused by the loss of one engine. The ability to stabilize the aircraft during this critical moment is essential for ensuring safe navigation towards a landing or a safe return to the airfield.

Other aspects, such as speed management or passenger behavior, may be relevant in an emergency context, but they do not directly address the immediate challenges posed by an engine failure. Fuel consumption rates are also not a primary concern in an emergency engine-out drill, as the focus is to ensure that the aircraft remains controllable and stable. Thus, the emphasis on flight control and stability is paramount during these drills.
