摘要
A system and method for achieving vertical navigation by using a satellite based navigation system exemplified by a GPS system and implementing the vertical navigation features in an autopilot unit interfaced to the satellite based navigation system. The autopilot reads waypoint information output from the satellite navigation system and receives VNAV altitudes and other commands from the pilot. The autopilot then performs VNAV calculations and guidance in accordance with the VNAV program. VNAV setup and progressive status are displayed on an economical small screen autopilot display. Modes are disclosed for exemplary GPS direct to waypoint VNAV, waypoint transition VNAV, multiple waypoint VNAV and other VNAV modes. Safety limits may be imposed on the VNAV program.
