Modular avionics systems architecture (MASA) test and diagnostics

Summary form only given. The US Air Force´s Modular Avionics Systems Architecture (MASA) Support Requirements document delineates some stringent testability requirements that must be met to succeed in reducing logistics support costs through modular avionics. A modular avionics handbook has been developed to provide guidelines for effective application of modular avionics. The author examines these testability requirements in the context of ongoing analyses and pre-milestone I and IV development planning initiatives of the newly chartered Joint Integrated Avionics Directorate (JIAD), specifically the T-38 Avionics Upgrade Study and the MASA demonstration project.<>
