METHODS FOR PREDICTING A SPEED BRAKE SYSTEM FAULT

摘要

Methods of predicting a speed brake fault in an aircraft having a speed brake system including multiple control surfaces, a handle for setting the position of the multiple control surfaces, and at least one control surface position sensor, the methods include receiving a position signal from the at least one position sensor, determining a variation in the position signal and predicting a fault in the speed brake system.

1. A method of predicting a speed brake fault in an aircraft having a speed brake system including multiple control surfaces, a handle for setting the position of the multiple control surfaces, and at least one control surface position sensor, the method comprising:
receiving a position signal from the at least one position sensor indicative of a position of at least one of the multiple control surfaces; comparing the position signal to a reference position value to define a position comparison; determining from the position comparison a variation parameter indicative of the variation of the position signal from the reference position value; comparing the variation parameter to a variation reference value to define a variation comparison; predicting a fault in the speed brake system based on the variation comparison; and providing an indication of the predicted fault.
