What does the term 'turn' mean in the context of aircraft operations?

In the context of aircraft operations, the term 'turn' refers specifically to the process of deplaning, servicing, and boarding for the next flight. This operational phase is crucial for maintaining the efficiency and schedule of airline operations. During a turn, the aircraft is typically parked at the gate, and various activities occur to prepare it for its next journey. This includes passengers disembarking, the aircraft being cleaned, catering services being performed, and ensuring that the necessary maintenance checks are completed.

Successful management of the turn is essential for on-time departures and overall operational effectiveness, as it allows airlines to maximize aircraft utilization and minimize ground time. Understanding this definition helps clarify the importance of the turn in ensuring a seamless transition between flights, which is a vital aspect of airline operations.
