What is the maximum torque in ft-lb that the engine can handle with the autothrottles and pneumatic torque-limiters operative?

The maximum torque that the engine can handle with the autothrottles and pneumatic torque-limiters operative is 2230 ft-lb. This figure is based on the engineering specifications and operational limits defined for the system.

In this context, the value reflects the optimal operating conditions under which the engine can perform efficiently without risking damage or failure. The autothrottles help maintain the desired performance by automatically adjusting the engine's throttle position in response to varying load conditions, while the pneumatic torque-limiters serve to prevent the engine from exceeding torque limits that could lead to mechanical failure.

By integrating these two systems, the engine can effectively utilize its mechanical capabilities while ensuring safety and reliability. The specified maximum torque value is thus established to balance performance with the need to protect engine components, ensuring longevity and stability in various operational scenarios.
