is aware of the source and the point of reference of the distance measurement.
Note   Here are examples of source and the point of reference: 115 GNSS ML VOR, 80 GNSS CTM NDB, 267 GNSS BEEZA 86 DME BN.
       (3) When supplying GNSS-derived distance information, the pilot in command must ensure that the information is obtained:
(a) from an approved GNSS; and
(b) by reference to data from a valid database.

11.06 ACAS resolution advisory
        In any class of airspace, whether controlled or uncontrolled, in the event of an ACAS resolution advisory (an RA), the pilot in command of an aircraft must:
(a) respond immediately by following the RA as indicated, unless doing so would jeopardize the safety of the aircraft; and
(b) follow the RA even if there is a conflict between the RA and an ATC instruction to manoeuvre; and
(c) limit the alterations of the flight path to the minimum extent necessary to comply with the RA; and
(d) promptly return to the last assigned level when the conflict is resolved; and
(e) notify ATC when returning to the last assigned level.
Note   When this section is complied with, an RA satisfies the requirements of subregulation 91.257 (2) that is, it is a defence to the offence of failing to comply with an ATC clearance or instruction.

11.07 RVSM airspace
       (1) This section applies to a pilot in command of an aircraft conducting a flight in a class of airspace that is RVSM airspace.
       (2) The pilot in command must conduct the flight in accordance with procedures published in the authorised aeronautical information.
       (3) When changing levels in RVSM airspace in an Australian FIR, the pilot in command must ensure that the aircraft does not overshoot or undershoot its cleared FL by more than 150 ft.
       (4) If the cleared FL cannot be maintained, the pilot in command must:
(a) inform ATC as soon as possible of the circumstances; and
(b) either:
           (i) obtain a revised ATC clearance (a revised clearance) before initiating any deviation from the cleared route or FL (the deviation); or
           (ii) if a revised clearance cannot be obtained before the deviation, obtain a revised clearance as soon as possible after the deviation.
       (5) If it is not possible to obtain a revised clearance for an operation within RVSM airspace in an oceanic control area in an Australian FIR, the pilot in command may initiate a temporary lateral offset procedure with the intention of returning to the cleared route as soon as possible.

11.08 Requirements for flight in the NAT-HLA
       (1) This section applies to a flight in a portion of a class of airspace that is the NAT-HLA.
       (2) The pilot in command
