An aircraft automatic or semiautomtic vertical path control system which coordinates operation of pitch and engine thrust control systems to transfer speed control from one system to the other depending on a requirement to climb, descend, or maintain altitude as determined by the polarity and magnitude of the difference between a selectable desired altitude and current actual altitude.

An aircraft flight path control system comprising a pitch axis control system (64), and engine thrust control system (84), and means for providing a signal representative of a desired selected reference speed (22), means (12) for providing logic command signals in response to desired climb, descend

An aircraft flight path control system comprising a pitch axis control system (64), and engine thrust control system (84), and means for providing a signal representative of a desired selected reference speed (22), means (12) for providing logic command signals in response to desired climb, descend or maintain altitude maneuvers of said aircraft; said flight path control system further comprising a selectable flight level change mode means (FLCH) (20) for enabling switching means (60, 62, 66) responsive to said logic command signals for automatically selecting said pitch axis control system (64) to control the aircraft to said selected reference speed (22) when said aircraft is commanded to climb or descend, and for automatically selecting said engine thrust control system (84) to control the aircraft to said selected reference speed (22) when said aircraft is commanded to maintain a predetermined altitude. *** BRS DOCUMENT BOUNDARY ***
