What is the maximum duration the engine can operate ON before requiring a 5-minute OFF period?

The correct response indicates that the engine can operate continuously for a maximum duration of 30 seconds before it necessitates a mandatory 5-minute cooldown period. This limitation is particularly critical during high-temperature operating conditions or instances of high throttle settings, where prolonged engine operation can lead to overheating or excessive wear. Consequently, adhering to this operational limit helps prevent engine damage and enhances safety during flight operations.

Understanding the specifics of engine limitations is crucial for pilots and maintenance personnel, as it ensures both the longevity of the aircraft's engines and the safety of its operations. Ignoring these limitations could lead to severe mechanical failure or reduced performance during flight.
