Discusses the evolution of Area Navigation (R/NAV) for air traffic control and outlines some computer systems presently available or being developed. The R/NAV concept originated in the USA with the impending saturation of established airways. New airways could be created by installing new ground beacons, but the problems of expanding the ground infrastructure are overcome in R/NAV by defining phantom markers, waypoints which do not exist on the ground and are referenced to conventional navigation transmitters. The waypoint reference data are held within airborne computer systems. New routes can be created and standardised, indicated on radionavigation maps and marked entirely by phantom beacons for use by aircraft in the IFR mode. R/NAV may be compulsory by 1982 for all IFR flight in the USA.
