How much foot-pounds of torque does the engine produce at the prop shaft at 100% indicated torque?

The engine produces 2750 foot-pounds of torque at the prop shaft at 100% indicated torque, making this the correct response. This value is significant because it reflects the maximum torque output capabilities of the engine under full power conditions. Understanding this value is crucial for various operational considerations, such as determining the appropriate settings for aircraft performance and handling characteristics during flight.

The torque measured at the prop shaft is a pivotal metric for pilots and engineers, influencing decisions regarding engine management, takeoff thrust, and climb performance. Recognizing this figure allows for an in-depth comprehension of the engine's performance envelope and ensures optimal utilization of the aircraft's powerplant.
