What is the transient maximum ITT range?

The transient maximum Interstage Turbine Temperature (ITT) range is vital for ensuring engine performance during short bursts of power. The correct range of 821 to 870°C reflects the operational limits established to maintain engine integrity during transient conditions, such as when the engine transitions between power settings. These temperature limits are designed to prevent thermal stress and potential damage to engine components.

Operating within this range allows for optimal performance while still protecting the engine materials and ensuring longevity. Understanding these limits is crucial for flight safety and engine management, particularly during phases of flight that may require sudden power changes.
