What is the minimum time to wait in seconds after each starting attempt?

The minimum time to wait after each starting attempt for the T-6A is specified as 30 seconds. This waiting period is essential to allow the engine and starting system components, which can become heated during the starting process, to cool down before another attempt. This precaution helps prevent potential damage to the engine and associated systems, ensuring safe operation and extending the lifespan of the aircraft's components. Waiting the appropriate amount of time is crucial for both the performance and reliability of the engine start procedure.
