What is the maximum IOAT at start for the aircraft?

The maximum Inlet Oxygen Air Temperature (IOAT) at start for the aircraft is specified as 80º C. This temperature is crucial because it ensures the engine operates within its designed parameters during start-up, preventing overheating and potential damage to engine components. Operating within this maximum threshold helps maintain the performance and longevity of the engine.

Monitoring the IOAT at start is essential for pilots and maintenance crews, as exceeding this temperature can lead to inefficient combustion, reduced thrust, or even malfunction during the critical start phase of engine operation. The specified 80º C acts as a guideline to ensure safe and optimal performance when starting the aircraft engines. Recognizing the parameters surrounding IOAT enables operators to adhere to safety protocols and maintain the aircraft's integrity during various phases of operation.
