Merlin avionics test system. A COTS solution

The Merlin avionics test system (MATS) provides a comprehensive second line (intermediate level) test solution for the avionic fit of the Royal Navy's new anti-submarine helicopter the Merlin. Developed by Serco Test Systems and Harris Government Aerospace Systems Division, the MATS provides an automatic test capability covering some 140 line replaceable units (LRUs) and is based on extensive use of COTS. The MATS is due to enter service in 1998. This paper discusses the MATS requirement, and outlines the design solution. The paper also includes discussion of the experience to date in the widespread use of COTS instrumentation.
