(b)
when aircraft are operating within controlled airspace within 60NM of Te Weraiti SSR site, the standard may be reduced to MNM 3NM; or
(c)
whenaircraftonreciprocaltracks have passed and their radar position symbols have separated, radar separation exists.
4.13.2 Radar separations applicable when wake turbulence is a factor are shown in AD 1.6.
4.14 Position Information
4.14.1 Radar controllers will pass position information in one of the following forms:
(a)
as a well known geographic position;
(b)
magnetic track and distance to a significant point or navigation aid;
(c)
bearing (using points of the compass) and distance from a known position;
(d)
position relative to the centreline of an ATS route, or the final approach track of an instrument approach; or
(e)
distance from touchdown, particularly for aircraft on final approach.
4.14.2 Aircraft under radar control will be informed of their position in the following circumstances:
(a)
on first identification, except where the identification is based on a pilot’s report of the aircraft’s position, on departure, or by use of a discrete SSR code and the position is consistent with the known track of the aircraft;
(b)
when the aircraft requests this information;
(c)
when the aircraft’s estimate differs significantly from the radar controller’s estimate based on radar observation;
(d)
at intervals when on a radar heading, particularly when being vectored for an instrument approach;
(e)
as necessary when the aircraft is resuming its own navigation after radar vectoring; and
(f)
when the aircraft is off track to the extent that it is outside the navigation tolerance for the type of navigation aid being used.
4.15 Radar Departure Procedures
4.15.1 Departure instructions may contain an altitude restriction to a point from which climb to MSA for the succeeding route sector is possible. The purpose of this restriction is to provide non-radar separation until identity is established and radar control can be exercised.
4.16 Radar Approach Procedures
4.16.1 The pilot will be advised of the type of approach for which the aircraft is being radar vectored and the radar controller will pass information applicable to the type and stage of the approach procedure.
4.16.2 The type of approach will be the most appropriate approach procedure for the runway in use, having regard to the prevailing MET conditions and traffic.
Intermediate or Final Approach
4.16.3 An aircraft will be vectored so that it will be established on final approach at a level and distance that will enable the pilot to comply with the final approach procedure.
4.16.4 When the final approach procedure includes a specified glide path or vertical path angle, vectoring will enable the aircraft to be firmly established in level flight on final approach prior to intercepting the nominal glide path.
4.16.5 If an aircraft has to be vectored through the centreline of a pilot interpreted approach, the pilot will be advised of the controller’s intentions and the reason for the track extension (e.g. sequencing). If no advice is given to a pilot when the aircraft is on base leg, the pilot is to intercept final approach and advise ATC. This covers possible loss of communications and is particularly important where there is rising terrain on the opposite side of the approach track.
Radar Vectoring for Visual Approach
4.16.6 An arriving aircraft may be radar vectored for a visual approach:
