Digital Datcom is evaluated as a tool for predicting the subsonic aerodynamic characteristics of forward-swept-wing aircraft. Comparisons are made with wing-alone and wing-body wind tunnel data as well as three complete configurations: two generic (one being sweptback) and the X-29. Good agreement between tested and predicted longitudinal and lateral-directional stability derivatives is noted but the zero-lift pitching, moment is not well estimated for X-29. Control derivative estimates match test data well except for aileron-induced yawing moment.
