Testing the integration of a new digital avionics navigation and weapon delivery system, including the interface with its sensors, into an aging aircraft with an analog system can be filled with problems. During previous flight tests, a 3/1 ratio of flown/productive flights was experienced. A current productivity rate approaching 100 % can be related to pre-mission testing of software, and real time display of test data. Pre-mission testing consists of loading the test software into a test simulator, and performing simulated tasks to verify operation of the test software prior to loading it into an aircraft for flight. Real time display of test data is accomplished by inserting a software overlay into the airborne computer which outputs data to an external instrumentation pod, where the data are recorded and transmitted via microwave to the ground control facility. The displayed data include switch settings, system errors, ground track of the aircraft, and software discretes.
