What is the maximum ITT during takeoff?

• A. 810 C
• B. 755 C
• C. 860 C
• D. 800 C

Answer: (A)

The maximum Interstage Turbine Temperature (ITT) during takeoff for the TH-73A is 810 degrees Celsius. This limit is crucial as it represents the maximum allowable temperature of the gas flowing through the engine during the high-power demands of takeoff. Adhering to this limit ensures optimal engine performance and longevity, preventing any potential damage that excessive temperatures can cause. Operating within this guideline helps pilots maintain a safe margin and prevents engine management problems.

Recognizing the importance of the ITT limit, other temperature values, while close, do not meet the specifications set for takeoff operations. Therefore, it's essential for pilots and aircraft operators to be familiar with these parameters to operate the TH-73A safely and effectively.
