What RPM range is optimal for cruise flight in T-6?

The optimal RPM range for cruise flight in the T-6 is between 50 to 60% Np. This range is specifically chosen to balance performance and efficiency during cruising conditions. Operating within this RPM range allows the aircraft to achieve an ideal power setting, which enhances fuel efficiency while maintaining adequate thrust for level flight and smooth operations.

When flying in cruise, it is important to optimize the engine's output to ensure the best range and endurance without overexerting the aircraft's systems. The 50 to 60% Np setting strikes a practical balance between power and fuel consumption, ensuring that the aircraft can travel longer distances while still being responsive to pilot inputs.
