What is the maximum ITT to advance the thrust lever from shut off to idle in the air?

• A. 80°C
• B. 90°C
• C. 100°C
• D. 110°C

Answer: (B)

The correct answer to the maximum Interstage Turbine Temperature (ITT) to advance the thrust lever from shut off to idle in the air is 90°C. This temperature limit is crucial for ensuring the safety and integrity of the engine during the start-up phase and subsequent operations. Advancing the thrust lever before reaching this thermal threshold can lead to potential engine damage due to excessive thermal stress. At or below this temperature, the engine components are more likely to withstand the thermal load associated with the transition to idle thrust. Understanding the significance of ITT limits is essential for pilots and aircraft operators, as it helps maintain engine performance and longevity during critical operations. Proper adherence to these limits supports safe flight operations and minimizes the risk of engine failure due to overheating.
