Abstract:

The technology of built-in-test and ASACC standards are studied for fault detection and location in the aviation electronic system.According to the multilevel structure of ASSAC standard,the system can be divided into node level,subsystem level and system level.Each level contains power up built-in-test,periodic built-in-test and maintenance built-in-test for the implementation of test of each phase in the system.The self detection system detects both the hardware state of the system and the starting and running state of the software,thus improving the self-detection ability of the airborne electronic system.

Key words: ASAAC;built in test;fault test
