First Claim
Patent Images
1. A method of predicting a speed brake fault in an aircraft having a speed brake system including multiple control surfaces, the method comprising:
- determining a position of at least one of the multiple control surfaces;
comparing the determined position to a reference position value to define a position comparison;
determining from the position comparison a variation parameter indicative of the variation of the determined position 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.

Abstract
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.

12. A method of predicting a speed brake fault in an aircraft having a speed brake system including multiple control surfaces and a handle, which controls a position of the multiple control surfaces, the method comprising:
-
determining a position of at least one of the multiple control surfaces; determining a position of the handle; defining a reference position value for the at least one of the multiple control surfaces based on the determined position of the handle; comparing the determined position of the at least one of the multiple control surfaces to the defined reference position value; predicting a fault in the speed brake system based on the comparison; and providing an indication of the predicted fault.
