11.18 Certain oceanic control areas — inoperative radio requirements
       (1) This section applies to a flight that is within Australian-administered airspace specified in the AIP as an oceanic control area.
Note   At the commencement of this instrument, the AIP document specifying the geographic boundaries of oceanic control areas is the Designated Airspace Handbook.
       (2) If the radiocommunication system becomes inoperative during the flight, the pilot in command must do the following:
(a) set code 7600 on the aircraft's transponder (if fitted);
(b) assume the radiocommunication system is broadcasting and, using the frequency appropriate to the area of operation:
 (i) broadcast position and intentions; and
 (ii) make normal position reports;
(c) keep a lookout for conflicting traffic, including by reference to ACAS and traffic displays;
(d) as far as practicable, turn on all exterior aircraft lights;
(e) maintain the last assigned speed and level for a period of 60 minutes following the aircraft's failure to report its position over a compulsory reporting point (including ADS-C flights), and thereafter adjust speed and altitude in accordance with the filed flight plan;
(f) upon exiting the oceanic control area, conform, as far as practicable, to the relevant State procedures and regulations.

Division 11.3 Prohibited, restricted and danger areas

11.19 Purpose

11.20 Prohibited areas
Note   For prohibited areas, see CASA's OAR 6-monthly Designation of Prohibited, Restricted and Danger Areas – Declaration and Determination (Permanent PRDs) Instruments and the relevant Designated Airspace Handbooks, as each exists, or is in force, from time to time. Entry or flight in a prohibited area is an offence under regulations 6, 15 and 16 of the Airspace Regulations 2007 and regulation 91.260 of Part 91 of CASR.

11.21 Restricted areas
Note   For restricted areas, see CASA's OAR 6-monthly Designation of Prohibited, Restricted and Danger Areas – Declaration and Determination (Permanent PRDs) Instruments and the relevant Designated Airspace Handbooks, as each exists, or is in force, from time to time. Unauthorised entry or flight in an active restricted area is an offence under regulations 6, 15 and 16 of the Airspace Regulations 2007 and regulation 91.260 of Part 91 of CASR.
