How long can the transient maximum torque reach 131%?

The transient maximum torque reaching 131% can be sustained for a duration of 20 seconds according to the operational limitations of the T-6A. This specific limitation is critical during performance maneuvers or emergency situations where increased torque is required temporarily. The duration of 20 seconds ensures that the engine is not subjected to prolonged stress, which could lead to damage or failure. The brief interval allows pilots to respond to situations requiring high power without compromising the integrity of the engine system in the long term. Understanding these time constraints is essential for safe and effective aircraft operation.
