What is the engine TRQ maximum continuous limit?

• A. 100%
• B. 115%
• C. 108.5%
• D. 110%

Answer: (A)

The maximum continuous torque (TRQ) limit for the engine is defined to ensure optimal performance and reliability during sustained operations. In the case of the TH-73A, the correct maximum continuous limit is indeed 100%. This figure represents the maximum torque that the engine can produce continuously without risk of damage or excessive wear. Operating within this limit is crucial for maintaining engine health and ensuring safe flight operations over extended periods. Exceeding this limit could lead to engine overheating, increased wear, or potential failure, which is why the NATOPS guidelines set this clear restriction. Understanding and adhering to this limit is essential for pilots during flight operations to ensure safety and efficiency.
