What is the maximum continuous engine ITT?

• A. 810 C
• B. 755 C
• C. 980 C
• D. 860 C

Answer: (B)

The maximum continuous engine Interstage Turbine Temperature (ITT) for the TH-73A is 755 degrees Celsius. This parameter is critical for ensuring the engine operates within safe thermal limits, thereby prolonging engine life and maintaining reliable performance during various flight conditions.

Maintaining engine temperatures within specified limits, like the 755 C maximum continuous ITT, helps prevent overheating, which can lead to decreased efficiency and potential damage to engine components. Understanding and adhering to this limit is a key component of safe operation and effective engine management in flight training and operational scenarios.

The other temperature options exceed the approved limit for continuous operation and would likely cause exceedances that can affect engine reliability and safety over prolonged use.
