Abstract
A contact analog aircraft display is described in which an airplane-like predictor symbol depicts future airplane position and orientation. The standard method for obtaining the predictor information is to use a complete, fast-time model of the controlled vehicle. An alternative approach is presented in this paper in which least-squares regression approximations for each of the six degrees of freedom of aircraft motion were calculated. Thirteen predictor variables representing changes in positions and rates of change of positions were selected as parameters for these prediction equations. The accuracy of the regression approach is evaluated both at various prediction times and at various control input durations. The advantages and disadvantages of such a regression procedure for generating predictor symbols are discussed.
