How long is the engine TRQ transient limit duration?

• A. 10 seconds
• B. 6 seconds
• C. 5 seconds
• D. 8 seconds

Answer: (B)

The engine torque (TRQ) transient limit duration is specified as 6 seconds. This limit is essential for maintaining the integrity and performance of the aircraft’s engine under transient conditions. Understanding this limit is crucial for flight operations, as exceeding it can lead to engine damage or failure.

In typical operational procedures, the transient torque conditions might occur during engine start, acceleration, or sudden changes in flight configurations. Recognizing that 6 seconds is the allowable time frame helps pilots and crew manage engine parameters effectively, ensuring safe operation without compromising engine health.

Awareness of these limits allows for optimal performance while adhering to safety standards set forth in operational guidelines.
