What is the limit for continuous operation above which engine temperature may cause damage?

In the context of the T-6 aircraft, the limit for continuous operation is critical for maintaining engine health and preventing damage. The maximum ITT (Interstage Turbine Temperature) for continuous operation is specified as 820°C. Exceeding this temperature can lead to excessive thermal stress on engine components, which may result in premature wear or failure.

Operating continuously above this threshold can compromise the integrity of the turbine, reduce its lifespan, and potentially lead to catastrophic engine failure. Thus, it's essential for pilots and operators to adhere to this limit to ensure safety and longevity of the engine. Understanding and respecting these temperature limits are crucial for effective aircraft operation and maintenance protocols.
