What is the takeoff/max temperature limit for ITT?

The takeoff/max temperature limit for Interstage Turbine Temperature (ITT) is crucial for ensuring the safe operation and performance of an aircraft engine. This limit is determined by the manufacturer and is a critical parameter that pilots must adhere to during takeoff to prevent potential damage to the engine due to overheating.

In this context, the 820ºC limit indicates the highest temperature at which the engine can safely operate during peak demand situations, such as takeoff. Operating at or below this ITT ensures that the engine can perform effectively while maintaining structural integrity and longevity. Exceeding this limit could lead to thermal stress and damage to the turbine components, compromising the engine’s reliability and safety.

It's important for pilots and maintenance personnel to be aware of these limits as they directly impact engine performance and aircraft safety.
