Abstract: First, by introducing flabby variable, remnant variable and artificial variable to form auxiliary object function Z1, and in addition applying operation of exchanging radix, the question of linearity planning is simplified; then, after pretreating the terrain data collected and adopting the correcting method of flight path angle, flight track planned is further modified and ideal reference track is obtained; last, as to the optimal flight tracks planned according to a variety of typical terrain, numeral sim...
