What is the maximum N_p percentage during takeoff?

The maximum N_p percentage during takeoff is 100%, which corresponds to the engine being at full power. During takeoff, the T-6A Texan II’s engine is designed to operate at maximum performance to ensure sufficient thrust for climb-out and acceleration. Operating at 100% N_p allows the pilot to achieve optimal engine output necessary for takeoff and assures compliance with performance standards.

Values above this (such as 105%) are not allowed as they exceed the engine's design specifications for continuous operation, which increases the risk of engine damage or failure. Thus, adherence to the 100% limitation is critical for safe operation during takeoff phases. Other options either suggest percentages that are suboptimal for takeoff or exceed safe operational limits.
