Common S2ENCE maintenance

Intermediate level avionics maintenance requires diagnostic assessment, repair, and flight certification steps. The current Automated Test Systems (ATS) are primarily designed to verify equipment end-to-end function (flight certification), so they are not optimized to support diagnostic procedures. An operator typically performs problem diagnosis at the beginning of the end-to-end test without any automated access to existing evidence of the likely failure. Test Program Set (TPS) routines can take hours for a functioning unit and much longer if repairs are necessary.
