For in-flight starts, what is the maximum duration for attempt 1 of the starter?

The maximum duration for attempt 1 of the starter during in-flight starts is 120 seconds. This limitation is crucial for the operational safety of the aircraft, as prolonged starter engagement can lead to overheating and potential damage to the starter motor or associated systems. Adhering to this timeline ensures that the starter can effectively function without risking component failure.

The prescribed duration maintains a balance between allowing sufficient time for the engine to start while also protecting the mechanical integrity of the starting system. Understanding these limitations is essential for pilots to ensure that they follow safe operating procedures and avoid scenarios that could jeopardize the aircraft's performance or safety.
