Which operation is NOT typically a part of turn-around time management?

Turn-around time management focuses on ensuring that an aircraft spends minimal time on the ground between landing and takeoff to maintain an efficient schedule. This involves several critical operations such as fueling the aircraft, loading and unloading baggage, and cleaning the aircraft to prepare for the next flight.

Conducting passenger surveys, while useful for assessing customer satisfaction and improving services, does not directly contribute to the operational efficiency associated with turn-around time. Instead, surveys may take place at different intervals unrelated to the immediate turn-around process, typically during or after a flight rather than during the time the aircraft is on the ground for servicing. Thus, while necessary for overall service improvement, it does not fit within the specific tasks aimed at managing and reducing turn-around time.
