Without ATC vectoring, the instrument approach procedure (IAP) may not have a published initial approach. Fr: RADAR REQUIS radar return Other expression for: radar echo radar route A flight path or route over which an aircraft is vectored. Navigational guidance and altitude assignments are provided by ATC. Fr: route radar radar separation The spacing of aircraft in accordance with established minima, based on information derived from radar sources. Fr: espacement radar radar service A service, provided directly by means of radar, that includes radar advisory, radar control service, radar monitoring, radar navigational assistance and radar separation. Fr: service radar “Radar service terminated” An expression used by ATC to inform a pilot that he or she will no longer be provided with any of the services that could be received while in radar contact.
