What is the maximum ITT limit before a restart attempt, in degrees Celsius?

• A. 850
• B. 871
• C. 900
• D. 950

Answer: (B)

The maximum Inter-Turbine Temperature (ITT) limit before a restart attempt is 871 degrees Celsius. This limit is critical to ensure the engine components remain within safe operating conditions and to prevent damage or failure during the restart process. Exceeding this temperature can lead to severe consequences, including engine performance degradation and potential safety hazards.

Understanding this limit is essential for operations involving engine restarts, particularly in high-stress situations. Choosing the right temperature ensures that pilots and maintenance crews can make informed decisions that prioritize safety and engine integrity. The other temperature values presented exceed the established limit, thereby placing the engine and the aircraft at risk during a restart attempt.
