This paper presents highly intriguing preliminary results concerning the mathematical model of human pilots hovering over a moving landing pad in an X-22A VTOL aircraft. The results are in the form of a time domain mathematical model which was determined from transient responses of the X-22A. The pilot, using both a head-up-display for landing pad position information and the outside visual scene for attitude information, was asked to precisely hover over a simulated landing pad which would move in semi-random step-like jumps. Since the X-22A (with its translation rate control system) was also driven by simulated ship wake turbulence and natural turbulence, the pilot's task was to track step inputs while correcting for random disturbances.
