For what parameter is the maximum continuous ITT value specifically noted?

The maximum continuous inter-turbine temperature (ITT) value is primarily associated with engine performance. It represents the highest temperature that an engine can sustain continuously without risking damage or degradation of the engine components. Maintaining the ITT within prescribed limits is crucial for ensuring optimal thrust output while preventing engine overheating, which could lead to failures or decreased reliability.

The ITT is a critical parameter for engine monitoring, especially in the context of various operating phases, including climb, cruise, and descent. Operating an engine at or below the maximum continuous ITT ensures longevity and minimizes maintenance issues, thereby enhancing overall operational safety and efficiency.

Thus, focusing on the correct management of this parameter is fundamental for pilots, especially in a Part 135 context where operational regulations demand strict adherence to such performance limits to ensure aircraft safety and compliance with regulatory standards.
