The USAF Ada Simulator Validation Program was designed to test the suitability
of Ada for the realtime requirements involved in aircraft simulators.

        BOEING Military Airplane Company, Huntsville Al. redesigned the
existing E-3A AWACS simulator to run under Ada.

        BURTEK Inc, Tulsa, Ok. implemented the C141B flight simulator using
Ada.
        Each project ran to approximately 100,000 lines of code and came in
on time. The USAF evaluation indicated speedup in execution of many sections
of code, as well as excellent subjective reports from the pilots testing
the simulators.

        I take pride in mentioning that both projects were based on Gould
computers. The compiler was the Gould APLEX implementation of the
Telesoft Telegen II compiler.
