What is the maximum normal takeoff ITT for the General Electric CF34-8E5 engine for 2 minutes?

The maximum normal takeoff Interstage Turbine Temperature (ITT) for the General Electric CF34-8E5 engine, as specified in the engine’s limits, is indeed 965 degrees Celsius for a duration of 2 minutes. This temperature limit is critical for ensuring the engine operates within its designed thermal capabilities during takeoff, which is a period of significant power demand.

Engine manufacturers provide these maximum temperature specifications based on extensive testing and data to guarantee that the engine can sustain the necessary performance while preventing potential damage from overheating. Operating within these limits supports not only the engine's longevity but also the safety and efficiency of the aircraft.

When pilots conduct takeoff procedures, adhering to these ITT limits is essential, as exceeding them can lead to severe engine wear or failures. Therefore, recognizing and applying the correct temperature limit during crucial flight phases is vital for operational safety and performance optimization.
