A path object is a set of instructions plus the values of associated parameters that would be used by an aircraft’s flight management system (FMS) or area navigation (RNAV) computer to construct a flight trajectory on the basis of the values of the parameters provided by the pilot or air traffic control (ATC) system. The concept of path objects and its applicability for development of FMS- or RNAV-based flight paths for aircraft routes are described. The use of path objects requires only a small number of parameters for specification of an RNAV route, and the computer then calculates the resulting flight path. Because most RNAV routes are just variations of the same basic shapes, many RNAV routes can be generated from a single path object by changing just one or two parameters. This offers the capability to reduce the size of the navigation database by a significant amount. This also allows the dynamic alteration of three-dimensional FMS-RNAV routes instead of radar vectoring, which represents a significant improvement in ATC procedures. Because of the compact expressions for the path objects, these procedures could be used in a voice communications environment as well as a data link environment. A path object can be thought of as a high-level language with which aircraft and ATC systems communicate flight path intentions. The concept of FMS- or RNAV-stored path objects is a change in thinking about the role of avionics technology. It offers a means of including the precision of the FMS-RNAV technology in the ATC system during the transition from today’s system to the future’s fully automated control system. This is an enabling technology that improves the ability to use and maintain FMS-RNAV in its role as a vital component of the ATC system. It has the potential to enhance future air traffic management-communication navigation surveillance concepts and applications.

This paper proposes that the navigation and control of all airliners should be automated from take-off to landing. Each aircraft will fly according to a prescribed flight plan, to be fulfilled in position, altitude and time within prescribed tolerances. The optimal flight plan is elaborated by a central air traffic control station and transmitted by data link to an airborne computer which monitors the navigation of the aircraft. The navigation itself is based on an integrated Inertial/DME/DME system. Separate airways are proposed for the general aviation. The paper was presented at the 19th Technical Conference of I.A.T.A., Dublin, October 1972.The permanent growth of air traffic demands rigorous regulation. The most efficient form of regulation is the careful elaboration of a flight plan, taking into account the total air traffic in the area and the rigorous fulfilment of this flight plan. The flight plan will be elaborated at a central air traffic control station by computer, taking into account both air traffic and the meteorological conditions, especially wind. This flight plan is transferred by radio to the computer in the aircraft and comprises essentially the three-dimensional coordinates of take-off point, destination and way points as well as the corresponding times; also the precomputed values of ground speed, rate of climb and rate of descent.
