The electronic governor will maintain Np at what percentage with the PMU functioning?

The electronic governor in the T-6A is designed to precisely manage the propeller speed, ensuring optimal performance and efficiency during flight. When the Power Management Unit (PMU) is functioning properly, it sets the propeller speed to maintain a constant Np value of 100%. This is a crucial aspect of the aircraft's engine management system, designed to avoid over-speeding or under-speeding the propeller, which can adversely affect performance and safety. The 100% Np value represents the aircraft's maximum efficiency, allowing the engine to operate within safe limits while providing the necessary thrust for flight maneuvers.

Therefore, the choice indicating a maintenance of Np at 100% reflects the intended function of the electronic governor in conjunction with the PMU, which is essential for ensuring that the aircraft operates safely and effectively.
