Chapter 5 Radar Phraseology
1 General
1.1 Introduction
1.1.1 This Chapter contains general radar phraseology which is commonly used in
communications between aircraft and all types of radar unit. Phraseology which is
more applicable to approach radar control or area control is to be found in Chapters 6
and 7 as appropriate.
1.1.2 The phrase 'radar control' shall only be used when a radar control service is being
provided. Normally however, the callsign suffix used by the radar unit is sufficient to
indicate its function.
1.1.3 In a radar environment heading information given by the pilot and heading instructions
given by controllers are normally in degrees magnetic.
1.2 Radar Identification of Aircraft
1.2.1 An aircraft must be identified before it can be provided with an ATS surveillance
service. However, the act of identifying aircraft is not a service in itself and pilots
should not assume that they are receiving an ATS surveillance service, particularly
when they are flying outside controlled airspace.
