What is the maximum torque limit during takeoff?

The maximum torque limit during takeoff is specified as 100%. This limit is significant because it represents the peak operational capacity of the engine and drivetrain in a helicopter or aircraft at the moment of takeoff. Operating at this level ensures that the vehicle has the required thrust to lift off while maintaining engine integrity and system reliability.

Exceeding this limit could lead to mechanical failure or reduced airframe safety, as the systems are not designed to handle prolonged stresses beyond the rated capacity. Therefore, adhering to the 100% torque limit during takeoff is crucial for safe and effective operation. It's a standard operating procedure within aviation to ensure that pilots and operators maintain this limit to mitigate risks associated with excess torque, which could affect aircraft performance and safety.
