Abstract:
1. A system for providing aircraft vertical navigation comprising: an autopilot system configured for combining gyro information, barometric altitude information, and GPS navigation information to produce servo control signals for controlling said aircraft, said autopilot system not including a GPS receiver; said autopilot system configured for receiving a data stream from a GPS receiver separate from said autopilot system, said data stream comprising waypoint information said waypoint information comprising at least one waypoint entered in said GPS receiver, said data stream further comprising aircraft velocity information and a distance to said at least one waypoint; said autopilot system comprising an autopilot programmer, said autopilot system configured for displaying said at least one waypoint to a pilot using said autopilot programmer and for receiving a target altitude from said pilot and associating said target altitude associated with said at least one waypoint; said autopilot system configured for determining an altitude difference by comparing said target altitude with said barometric altitude information; said autopilot system configured for calculating a vertical rate or slope by combining said distance to said at least one waypoint, said aircraft velocity information, and said altitude difference; said autopilot system configured for controlling said aircraft to fly in accordance with said vertical rate or said slope.
