IDENTIFICATIONPROCEDURES
Beforeproviding anATS surveillance service therewill bepositive
identification of the aircraft concerned. However, control serviceswill not be
provided until the aircraft iswithin controlled airspace.
RADARVECTORINGPROCEDURES
On receipt of heading instructions thepilotmust, unless otherwise instructed,
immediately commence a rate 1 turn, or the standard rate of turn for the
aircraft type, and thenmaintain the heading given.
Aircraftwill normally be vectored on routes alongwhich thepilot canmonitor
navigation.
ATC are not permitted to vector special VFR flights.
When an aircraft is given a vectorwhichwill take it off anestablished route,
the pilotwill be advised of the reason for the vector, unless it is self-evident.
When an aircraft reports unreliable directional instruments, thepilotwill be
requested, prior to the issuanceofmanoeuvring instructions, tomake all turns
at an agreed rate and to carry out the instructions immediately on receipt.
When aircraft are radar vectored, the controllerwill assign altitudeswhich
allow for terrain clearance. However, inVMC by day, an aircraftmay be
permitted to arrange its own terrain clearance. In such instances the aircraft
will be instructed toCLIMB (or DESCEND) TO (level) VISUAL.
Pilots being radar vectoredwill be routinely advisedof their position toenable
pilot navigation in the event of radioor ATS surveillance system failure.
The interval betweenATC transmissionswill be kept short toenable the pilot
to quickly recognise a communication failure.When aircraft areon headings
that could infringe terrain clearance or separation standards, the intervals
between transmissionswill not exceed 30 seconds.
Before take-off, ATCmay asign a heading for a departing aircraft to assume
after take-off, followed by frequency change instructions if appropriate.
Headings, other than those assigned for a standard radar (SID), will only be
issued for a visual departure by day inVMC.
Arrivingaircraftmaybevectored to:
• establish for a radar or pilot-interpreted approach;
• a position fromwhich a visual approach can bemade;
• avoid areas of hazardousweather or severe turbulence; and
• expedite traffic flow or conform to noise abatement requirements.
