4.2  RADAR PROCEDURES
              Radar Identification and Vectoring

              Before an aircraft can be given a radar service, the controller must positively

              identify which ‘blip’ on his screen is the aircraft requiring service. Usually this is
              done by giving the aircraft an SSR (Secondary Surveillance Radar) code to squawk,

              however if SSR is not available the controller will tell his ‘target’ to turn so that

              he may be identified on the radar screen.
              Note: Identification is not a service, the pilot is told when he has been identified and has a

              radar service e.g. “Radar Control”, he then acknowledges receipt of the service.


              Radar Vectoring
              Radar vectoring means that an aircraft may be told to fly specific headings by

              the radar controller. Pilots may be told the reason for this, but not always. Pilots

              may also request radar vectors in situations such as radar vectors to the ILS (final
              approach), avoiding severe weather ahead or to the next position / airfield.



              Headings
              The controller may wish to keep an aircraft on its present heading for a short

              while or change heading.

              Often the controller will ascertain the aircraft heading first:
                       “SPD turn left heading 300”  (heading tree zero zero)

              The clearance must be readback....

                       “Left heading 300 SPD”


              Vectoring Complete

              When vectoring is no longer required by the controller, pilots will be instructed
              to resume own navigation, and if necessary they will be given position and

              appropriate instructions as necessary.

                       “SPD, resume own navigation for Herning, position is 10 miles north of
                       Billund”

                        “Wilco, SPD”
