How long is a turnaround valid for?

The duration for which a turnaround is valid is 24 hours. This timeframe is crucial in the context of aviation operations, as it ensures that the aircraft has been thoroughly checked and is fit for further flights within a specified period. This 24-hour window allows for necessary inspections, maintenance actions, and any operational checks that may be required before the next flight. It provides a balance between safety and efficiency, allowing for timely operations without compromising the integrity of the aircraft. Understanding this timeframe is essential for those involved in aircraft maintenance and operational readiness, as it dictates the frequency of checks and certifications needed to keep the aircraft safe and operational.
