ABSTRACT:
Apparatus for use with an area navigation system wherein the craft is maintained on a predetermined vertical flight path. Specifically, a pitch command signal for controlling the vertical flight of the craft, which is substantially free of discontinuities, is produced by summing a signal indicative of the vertical displacement of the craft from the flight path with a damping signal representative of the vertical deviation rate of the craft from the vertical velocity required to maintain the craft on the flight path. Additionally, the vertical displacement signal is limited to a maximum amplitude to compensate for discontinuities therein, with respect to passage of the craft through the vicinity of a VOR/TAC station.
