What is the maximum ITT and how long can it be sustained?

The correct answer identifies that the maximum Inter Turbine Temperature (ITT) is 1,000 degrees Celsius, and it can be sustained for a duration of 5 seconds. This limit is crucial for ensuring the safety and longevity of the engine. Maintaining the engine temperature within specified limits is essential to avoid damage, reduce wear, and ensure the reliable operation of the aircraft.

Exceeding the maximum ITT can lead to potential engine failure, which could jeopardize flight safety. The time limit associated with this temperature is critical, as it allows for brief periods of maximum performance (like during takeoff or climb) without compromising the integrity of the engine. Understanding and adhering to these limitations is part of the training for pilots operating the T-6A, as they directly impact safe aircraft handling and engine management.
