Which of the following is NOT a common error during the FTI engine failure procedures?

The option stating that correcting with power is not a common error during engine failure procedures is accurate because using power to manage aircraft attitude and altitude appropriately during an engine failure is a crucial technique. In situations where an engine fails, the pilot must react quickly to maintain control of the aircraft. This includes using available power from the remaining engine, if applicable, to assist in managing the aircraft's performance and ensure a safe flight path.

In engine failure scenarios, pilots are trained to rely on aerodynamic principles and operational procedures that may involve adjusting power settings to achieve a safe glide or to maintain control. Therefore, appropriately correcting with power, when feasible, is typically viewed as a sign of effective handling of the situation.

The other choices—improper flap settings, poor energy management, and delayed approach checks—are considered common errors because they can lead to mishandling the aircraft during critical phases following an engine failure. For instance, improper flap settings can alter the aircraft's performance and affect landing approach stability, while poor energy management could lead to insufficient altitude or speed management, contributing to loss of control. Delayed approach checks can hinder a pilot’s readiness to respond to changing flight conditions, particularly in emergencies. These errors can severely impact safety, illustrating why they are highlighted as
