What is the starter limit time for starting the aircraft?

The starter limit time for starting the T-6A aircraft is 20 seconds. This limit is important to prevent overheating and potential damage to the starter motor. If the starter runs for longer than the prescribed limit, it can lead to failure or significantly reduce its lifespan.

After a successful start, if the engine does not start within this time frame, the procedure dictates that the starter must be allowed to cool for a specific duration before attempting another start. This is to ensure that the engine's starting system operates efficiently and safely, which is critical in maintaining overall aircraft reliability and performance. The other time limits listed do not align with the established starter operation parameters, making them incorrect.
