Verification and validation of F-15 and S/MTD unique software

Four separate operational flight programs (OFPs) were developed by five vendors, using seven computer languages, and were integrated for use in the STOL (short takeoff and landing)/Maneuver Technology Demonstrator (S/MTD). The verification and validation (V&V) process used was very successful, as evidenced by the fact that very few problems have been encountered during the test program, and no flights were delayed as a result of software anomalies. The authors provide an overview of the V&V approach used by MCAIR and its suppliers. The approach is not a management breakthrough; rather, it is the application of well-known, but often neglected, principles of engineering management, particularly attention to detail. Emphasis is placed on the V&V of the flight critical software for the flight controllers
