How long after block in at the gate is the release time typically set?

The release time is typically set 15 minutes after block in at the gate to ensure that all necessary post-flight duties are completed before the aircraft is released for the next flight or operation. This allows the crew to debrief, perform necessary inspections, and manage any issues that may arise after arrival, providing a clear and structured timeline for operations. It also accommodates any potential delays in turnaround processes.

The options related to shorter or longer release times may not provide adequate time for these important post-arrival activities and adherence to operational requirements, which are crucial for maintaining safety and efficiency in flight operations.
