If RADAR HEADING is such a useful term and is in regular use by ATCOs, then why the h*ll doesn't someone do something about it and get it into CAP413 so that instructors can teach it.
From CAP 413...
Chapter 1 Glossary
1 Definitions
Radar Vectoring Provision of navigational guidance to aircraft in the form of specific
headings, based on the use of radar.
Chapter 8 General Radar Phraseology
5 Radar Vectoring
5.1 Aircraft may be given specific vectors to fly in order to establish separation. Pilots may be informed of the reasons for radar vectoring.
5.2 It may be necessary for a controller to know the heading of an aircraft as separation can often be established by instructing an aircraft to continue on its existing heading.
5.3 A controller may not know the aircraft’s heading but does require the aircraft to fly a particular heading.
5.4 When vectoring is complete, pilots will be instructed to resume their own navigation, given position information and appropriate instructions as necessary.
I have omitted the examples....
Hope this helps
