vectoring if the current instructions had diverted the aircraft from a previously assigned route;

(e)         immediately before termination of ATS surveillance service, if the aircraft is observed to deviate from its intended route.

10.2.7              Use of Speed Control

10.2.7.1         Speed Control must not be applied to formation flights or fuel critical flights.

10.2.8              Termination of ATS surveillance services

10.2.8.1         When an aircraft exits controlled airspace into an area in which ATS surveillance services will continue, ATC must inform the pilot accordingly.

10.2.9              Obstacle clearance

10.2.9.1         When vectoring, ATC must provide at least 1 000 ft vertical clearance over any obstacle within:

(a)         3 NM of the aircraft when the range scale in not greater than 50 NM; or

(b)         5 NM of the aircraft when the range scale is greater than 50 NM.

10.2.9.2         These obstacle clearance requirements do not apply:

(a)         when vectoring as part of an issued SID; or

(b)         when ATC authorises a visual departure; or

(c)          in VMC by day only, when ATC assigns responsibility for arranging obstacle clearance specifically to the pilot.

10.2.10         Vectoring special VFR

10.2.10.1     Special VFR aircraft may be vectored only if warranted by emergency conditions.

10.2.11         Issuing ATS surveillance system derived distance

10.2.11.1     ATS surveillance system derived distance and appropriate altitude assignments may be issued to an arriving aircraft using a track for which a DME or GPS Arrival procedure is specified, if:

(a)         DME is not available; or

(b)         a pilot conducting a GPS arrival reports the loss of RAIM.

10.2.11.2     When ATS surveillance system derived distances are used as a substitute for DME or GPS derived distance information, the reference datum being used for the distance information (e.g. DME site) must be displayed on the situation display map.

Section 10.3:   Circuits and Runways

10.3.1              Selection of Runway in Use

10.3.1.1         Use of other than nominated runways. Controllers must not nominate a particular runway for use if an alternative runway is available, when:

(a)         for runway conditions that are completely dry, either:

(i)            the cross-wind component for the particular runway, including gusts, exceeds 20 knots; or

(ii)          the downwind component for the particular runway, including gusts, exceeds 5 knots;

(b)         for runway conditions that are not completely dry, either:

(i)            the cross-wind component for the particular runway, including gusts, exceeds 20 knots; or

(ii)          there is a downwind component for the particular runway.

10.3.1.2         Authorising intersection departures. A controller may authorise a departure from a runway intersection when requested by the pilot or may offer an intersection departure to assist traffic flow. The pilot must be advised of the remaining runway length if such information is not readily available to the pilot.

10.3.2              Simultaneous Parallel Runway Operations

10.3.2.1         In addition
