The accuracy of various methods used in wind tunnel experiments for the determination of the separation trajectory is investigated for various aircraft stores with flight test data. Trajectory analysis is performed with the aid of the geometric interface of an interactive 3-D numerical system. Low-velocity free drops are modeled using a Froude similarity criterion, and a six degrees-of-freedom system is used to study missile firings. With the exception of the rail-firing of missiles, good general agreement is found between separation data for the various stores considered, and the flight data. Initial conditions of the store that must be taken into consideration include variations of mass, center of gravity, Mach number, velocity, and incidence angle.
