18 Claims

1. A method for calibrating a torque sensor of an aircraft engine, the method comprising:

receiving input including an engine identifier from an engine and torque sensor parameters associated with a torque sensor of the engine;

determining a conformance of the engine identifier and torque sensor parameters to an expected engine identifier and expected torque sensor parameters for the engine;

when conformance is determined:

activating the engine:

measuring a raw torque from the torque sensor at the engine;

calibrating the raw torque using the torque sensor parameters to produce a calibrated torque value;

measuring non-torque parameters associated with the engine and applying the non-torque parameters to a lookup structure to obtain an expected torque value;

determining a separation of the calibrated torque value and the expected torque value; and

based upon the separation, controlling an operation of the torque sensor;

wherein controlling an operation of the torque sensor comprises deactivating the torque sensor.
