Abstract
An aircraft navigational system for providing a geometic display to the pilot of the vertical position of the aircraft relative to a selected vertical flight path profile as the aircraft progresses between its departure and destination. The vertical profile, which has a climb portion, a cruise portion and a descent portion, is formed by a number of navigational points, each of which is defined by an altitude component and a geographical position component. The profile points which form the climb and descent profiles are calculated from controller assigned altitude and waypoint constraints as well as from airspeed and altitude operating limitations which define various selected aircraft performance climb and descent modes.
