During VTOL/CONV operations, what is the normal mast torque percentage?

In VTOL (Vertical Take-Off and Landing) or CONV (Conversion) operations, the normal mast torque percentage is established at 100%. This value represents the maximum power output that the rotor system can reliably handle under normal operating conditions without risking mechanical failure or overloading the system.

Maintaining the mast torque at 100% ensures that the aircraft achieves the desired performance characteristics required during these flight modes while maintaining safety and efficiency. Operating consistently at this level allows the aircraft to perform necessary maneuvers, such as hovering or transitioning from vertical ascent to forward flight, without straining the rotor system excessively.

Exceeding this value, such as with percentages like 117% or greater, can lead to increased wear on the system or even catastrophic failure, especially in the unique flight dynamics present during VTOL and CONV operations. Therefore, keeping mast torque at 100% is critical for optimal performance and safety.
