10.1.1              Purpose

10.1.1.1         This Chapter contains the standards, rules and procedures for the provision of air traffic services that are additional to, or expand upon, or specify additional conditions for, the standards, rules and procedures contained in ICAO Annex 11, PANS-OPS Volume II, ICAO Doc 8168, ICAO Doc 7030 and ICAO PANS-ATM Doc 4444.

10.1.2              Air Traffic Services Commensurate with Airspace Classification

10.1.2.1         Unless otherwise authorised by CASA, air traffic services must be provided commensurate with the airspace classifications as notified in the AIP.

10.1.3              Traffic Priorities

10.1.3.1         Aircraft in a state of emergency must be given priority over all other traffic.

10.1.4              Relaxation of Speed Restrictions

10.1.4.1         Subject to subsection 10.1.4.2, in providing an air traffic service in Class D airspace, including a Class D CTR, ATC may permit an aircraft to exceed the 200 KT Class D airspace speed limit.
Note The 200 KT speed limit for Class D airspace is a CASA direction to pilots under subregulation 99AA (5) of the Civil Aviation Regulations 1988.

10.1.4.2         After taking account of air traffic conditions, ATC may permit:

(a)         a maximum speed limit of 250 KT; or

(b)         if the pilot in command of an aircraft informs ATC that a speed greater than 250 KT is an operational requirement — a maximum speed limit of greater than 250 KT.

10.1.5              SARWATCH for IFR Aircraft conducting VFR Operations

10.1.5.1         The unit providing an ATS to an IFR aircraft must provide a SARWATCH service for the aircraft if it is conducting any of the following:

(a)         a departure, climb or descent under the VFR;

(b)         a VFR-on-top procedure.

10.1.5.2         Subsection 10.1.5.1 does not apply if the pilot in command has expressly cancelled the IFR flight plan.
Note SARWATCH service is a function of the flight plan, not of the particular procedure being flown at the relevant time.

Section 10.2:   ATS surveillance systems

10.2.1              Use of ADS-B surveillance

10.2.1.1         ADS-B may only be used for the provision of air traffic control service if the quality of the ADS-B data is demonstrably suitable for the particular purpose.

10.2.2              Operation of ADS-B transmitters

10.2.2.1         If the situation display shows that the aircraft identification transmitted by an ADS‑B‑equipped aircraft is different from that expected from the aircraft, ATC must ask the pilot to confirm aircraft identification.

10.2.2.2         If, after a pilot has been instructed to operate the aircraft's ADS-B transmitter on an assigned aircraft identification or to change call sign, the aircraft identification shown on the situation display is different from that assigned to the aircraft, ATC must ask the pilot to re-enter the assigned aircraft identification.

10.2.2.3         If the identification of an aircraft as shown on the situation display is different from that assigned
