What is the term for the time spent readying the aircraft for its next departure?

The term for the time spent readying the aircraft for its next departure is known as "Turn" or "Turn Time." This process involves several key activities, including unloading passengers, refueling, cleaning, and performing necessary maintenance checks. The efficiency of this turn time is crucial for airlines, as it directly affects their ability to maintain schedules and maximize aircraft utilization. A well-managed turn time ensures that the aircraft can quickly transition from one flight to another, contributing to a streamlined operation and improved customer service.

The other terms listed, such as Air Time, Flight Prep Interval, and Ground Control Duration, do not accurately capture the specific activities and processes involved in preparing an aircraft between flights. Air Time refers to the time the aircraft is in the air, while Flight Prep Interval and Ground Control Duration are not standard terms commonly used in aviation to describe the turnaround process.
