COST-EFFECTIVE BUILT-IN TEST FOR ADVANCED AIRCRAFT ELECTRICAL SYSTEMS

This paper presents a method for utilizing the data handling portion of the Advanced Aircraft Electrical System (AAES) to provide a cost-effective built-in test capability to isolate faults to the line replaceable unit (LRU). The evolved techniques provide a means for determining the health of each of the 2048 input and 2048 output controls (signal transducers and power switches) that are multiplexed by the system. The system also automatically tests the integrity of all the aircraft electrical distribution system signal and power wire, terminations, and connector pins. Four techniques to automatically test the data handling and multiplex circuits are also discussed.
