11.22 Danger areas

  The pilot in command of an aircraft may fly within or across a danger area, but only if the pilot complies with any applicable requirements or conditions expressed in the following:

(a) until the end of 14 June 2023:

 (i) a declaration of the area as a danger area, made under regulation 6 of the Airspace Regulations 2007 (the AsR), as in force from time to time; and

 (ii) instrument CASA 26/21 – Direction – Australian Aircraft and Foreign Registered Aircraft in Australian-administered Airspace Instrument 2021 (CASA 26/21), or any CASA instrument that is expressed to be a successor instrument to CASA 26/21, as in force from time to time; or

(b) from 15 June 2023 — a declaration of the area as a danger area, made under regulation 6 of the AsR, as amended by the Airspace Amendment (Danger Areas) Regulations 2022.

Note 1   It is expected that a regulation amendment, to be known as the Airspace Amendment (Danger Areas) Regulations 2022, will make amendments to regulation 6 of the AsR in relation to danger areas that will affect section 11.22 on and from 15 June 2023 when the first Designation of Prohibited, Restricted and Danger Areas – Declaration and Determination (Permanent PRDs) Instrument for 2023 takes effect (see also Note 2).

Note 2   Danger area declarations are made or revised by CASA approximately every 6 months in the instrument known as Designation of Prohibited, Restricted and Danger Areas – Declaration and Determination (Permanent PRDs) Instruments. The declarations also appear in the Designated Airspace Handbooks, as each exists or is in force in the AIP, at the time of the flight.

Note 3   Flight in a danger area is subject to compliance with this section. The pilot in command of an aircraft should be aware of the specific activity which causes an area to be a danger area, and, while complying with this section, take appropriate precautions against any safety risks that could arise from the flight.

Note 4   It is an offence under subregulation 91.255 (2) to not comply with the section 11.22 requirements for a danger area.
