What is the time allowed for the maximum TRQ during transient operation?

• A. 6 seconds
• B. 5 seconds
• C. 10 seconds
• D. 15 seconds

Answer: (A)

The maximum torque (TRQ) limits during transient operations are defined to protect the engine and transmission components from damage while still allowing pilots to execute maneuvers effectively under specific circumstances. The standard time allowed for the maximum TRQ during transient operations is set at 6 seconds. This limit provides a balance between operational flexibility and mechanical safety, ensuring that while transient torque increases can be used momentarily for performance, there is also a definitive period established to minimize the risk of overstressing the system.

Understanding this limit is crucial for pilots operating the TH-73A as it impacts their ability to perform maneuvers safely within the aircraft's performance envelope. The option indicating a time allowance greater than 6 seconds could potentially expose the aircraft to risks of exceeding mechanical limits, while a shorter allowance could restrict critical operational capabilities.
