Abstract : A flight test program was designed and flown with two U.S. Navy F/A-18 aircraft and the Naval Air Warfare Center Aircraft Division, Patuxent River, MD to collect data for validation of the Manned Flight Simulator's F/A-18 aerodynamics model. This paper details the flight test program and the processes used to calibrate the flight data for the creation of a truth-data set to be used for the validation as well as source for future updates. The paper presents examples of preliminary aerodynamic coefficient comparisons between model predicted values and values extracted from flight. It also provides a discussion of a coefficient comparison acceptance criteria currently being developed.
