SST FLIGHT PLANNING AND NAVIGATION: THE FIRST YEAR'S EXPERIENCE

This paper examines the Concorde's operations in the light of experience, with emphasis on navigation and operational planning. Of special interest is the way in which the triple intertial navigation system on the aircraft has been used to ensure accurate and reliable track keeping on complex routes. It is noted that Concorde routes are constrained as much by political as by operational considerations and long term planning was necessary to obtain route profiles which gave the shortest distance and optimum acceleration/deceleration points. The London-Bahrain route involves subsonic flying over Europe with supersonic climb cruise over the Adriatic and Mediterranean Seas and over sparsely populated desert areas of the Middle East. The basic INS fit which has a "turn anticipation" distance of about 40 n.m at Mach 2 is described and its associated advantages and disadvantages are discussed. One of the advantages of the INS is its ability to bend a route with the minimum increase in track mileage. The false waypoint technique is described with respect to this particular route. The transatlantic London-Washington route revealed that a variable SST track system over the Atlantic had no advantage over a fixed track system. Acceleration and deceleration is constrained at both ends of the route. The application of false way points to particular problems associated with this route are included. The application of the INS approach on the return sector of the Atlantic operation is described.
