What is the maximum ITT allowed for takeoff thrust?

• A. 940 C
• B. 950 C
• C. 955 C
• D. 970 C

Answer: (C)

Takeoff thrust has a defined ITT limit to protect the engine during the high-temperature, high-thrust regime of takeoff. The maximum ITT permitted for takeoff thrust on the Citation Longitude’s GE Passport engines is 955 C. Staying at or below this limit ensures the turbine inlet temperature remains within safe margins for the takeoff event. Values like 940 C or 950 C are below the official takeoff limit, while 970 C would exceed it and could risk engine damage. Therefore, 955 C is the correct maximum for takeoff ITT.
