What should be done if the start ITT exceeds 830 degrees Celsius?

When starting an aircraft's engine, monitoring the ITT (Interstage Turbine Temperature) is critical to ensure safe operation. If the ITT exceeds 830 degrees Celsius, it indicates that the temperature is beyond the operational limits set by NATOPS (Naval Aviation Training and Operating Procedures Standardization).

Exceeding this temperature during the start procedure can potentially lead to engine damage or failure. Discontinuing the start is essential to prevent further complications, which may include damage to the turbine blades and other critical components. This precaution aligns with standard aviation safety protocols that prioritize the integrity of both the aircraft and its systems.

Taking prompt action in response to high ITT readings is a fundamental aspect of aviation safety. By recognizing the need to discontinue the start, operators help ensure the health of the engine and overall mission readiness. Proper training entails understanding these limits and responding appropriately when they are exceeded.
