An aircraft navigational system which provides flight data information for an aircraft to travel along a first airway to a point of intersection with a second airway and then along said second airway. The system determines whether the point of intersection is at a named waypoint common to both said first and second airways, or if the point of intersection is unnamed. If unnamed, the system computes the location of the unnamed point of intersection and provides flight path data to said unnamed point of intersection and then along said second airway.

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.
