4.11.5 ATC direct routing responsibility ceases when:
(a)
the aircraft crosses the navigation aid, significant/reporting point, or fix within controlled airspace that the aircraft has been cleared to; or
(b)
the pilot reports established on a promulgated route or procedure; or
(c)
the pilot reports establishedonaninstrumentapproach;or
(d)
the aircraft vacates controlled airspace.
4.11.6 The pilot of an aircraft using GNSS equipment as a primary means of navigation is permitted routing on unevaluated routes outside controlled airspace in accordance with relevant CAR.
4.11.7 ATC is not responsible for the obstacle clearance or navigation of IFR flights outside controlled airspace.
4.12 Terrain Clearance — IFR Flights
4.12.1 When providing radar control, ATC will assign levels that provide terrain clearance in accordance with:
(a)
contour levels depicted on radar displays that provide at least 1000ft (2000ft over designated mountainous zones or 3000ft over Volcanic Hazard Zones at Alert Level One) vertical clearance from obstacles within 5NM of any position within the contour; or
(b)
the MSA for the route or procedure being flown, including Enroute descent (Distance) or VORSEC/VORTAC chart steps; or
(c)
an approved area MSA; or
(d)
the altitude quoted on the 25NM minimum sector altitude diagram as shown on Instrument Approach and STAR/Arrival charts; or
(e)
the altitude quoted on a TerminalArrivalAltitude(TAA) diagramas shown on Instrument Approach and STAR/Arrival charts.
4.12.2 Notwithstanding the previous paragraph, in VMC by day an IFR flight arriving or departing under radar control may be permitted to arrange its own terrain clearance. In such instances the radar controller will instruct the pilot to “MAINTAIN TERRAIN CLEARANCE VISUALLY”.
4.12.3 Whenever a clearance or a number of clearances are issued to an aircraft subject to a radar terrain contour map, the pilot will be advised in the first transmission only that terrain clearance is being sourced from the radar terrain contour map. The following phrase will be appended to the clearances: “...RADAR TERRAIN”.
4.12.4 A departing aircraft may be cleared to make a visual departure onto a specified heading or track, in which case the altitude at which terrain clearance responsibility passes from the pilot to the controller will be specified as part of the clearance.
4.12.5 It is the responsibility of a pilot who is cleared to maintain terrain clearance visually to ensure obstacle clearance is maintained until an alternative procedure applies, or to a specified limit, or until the aircraft has landed.
4.12.6 Pilots must be aware that the navigational tolerance used to define the MSA may not be valid if, when descending below MSA while maintaining terrain clearance visually or descending in accordance with levels assigned from the radar terrain clearance chart, utilisation of the primary means of navigation cannot be continued.
4.12.7 Before vectoring a departing flight towards rising ground the radar controller will, when necessary, obtain confirmation from the pilot that the climb performance of the aircraft will be adequate to maintain the required terrain clearance.
