A turn is defined as an aircraft on the ground for less than how many hours?

• A. 2 hours
• B. 6 hours
• C. 8 hours
• D. 4 hours

Answer: (D)

A turn is the period an aircraft spends on the ground between flights, during which servicing, cleaning, and provisioning are done. The standard definition uses a four-hour threshold: if the aircraft is on the ground for less than four hours, that ground time counts as a turn. Times of four hours or longer are categorized differently, such as longer layovers or stopovers, because they allow more extensive ground activities or rest. So, the limit is four hours, and any ground time under that qualifies as a turn.
