What is the maximum transient ITT and for how long can it be sustained?

The maximum transient ITT (Interstage Turbine Temperature) is set at 870 degrees Celsius, and it can be sustained for a duration of 20 seconds. This information is crucial for maintaining engine integrity while allowing for a temporary increase in temperature during situations that may require additional power, such as takeoffs or go-arounds.

Understanding the operating limits for transient conditions is essential to avoid exceeding the maximum temperature for too long, which could lead to engine damage or failure. The specifications are designed to provide pilots with a clear boundary for engine operation while maintaining safety and performance. The other temperature limits and times do not match the T-6A's transient performance specifications, hence they are not the correct answers.
