Abstract :
A troubleshooting expert system has been designed to provide repair and diagnostic information for aircraft inertial navigation systems (INS). The inertial navigation system intelligent diagnostic expert (INSIDE) is used to diagnose faults in an INS system, and to train new operators on the troubleshooting of an INS system, thus freeing up the experienced engineer for other projects. INSIDE leads a new engineer through the conventional fault paths and step-by-step through repairs, thus alleviating the primary training and greatly diminishing the part-time training. The IN intelligent diagnostic expert uses a fault path algorithm. The fault tree is traversed by a rules-based inference engine written in the Level 5 expert system shell. It is comprised of one main, executive knowledge base and five more detailed knowledge bases. The system supports graphics, and interfaces with a BASIC program to perform simple, pertinent computations on the request of the operator
