9 Determination for voice-activated extension of certain Class C Control Zones

 (1) This section:

(a) applies for a relevant Class C Control Zone despite section 8 and Schedule 5; and

(b) ceases to have any effect at the end of 14 June 2023.

Note 1   Relevant Class C Control Zone is defined in subsection (5).

Note 2   The purpose of section 9 is to conduct a time-limited safety trial of Controlling Authority use of voice communication, in certain circumstances, in a relevant Class C Control Zone, to provide a 15‑minute, temporary extension of an otherwise about-to-expire activation of the relevant Class C Control Zone, to enable the passage and landing of overdue RAAF aircraft.

 (2) Subject to this section, I determine that a volume of airspace that is a relevant Class C Control Zone does not cease to be a Class C Control Zone if:

(a) the details for the Control Zone provide for its activation in accordance with an hours of activity statement that is a NOTAM (an activating NOTAM); and

(b) the activating NOTAM specifies a finish time for the activation (the specified finish time); and

(c) the Controlling Authority for the Control Zone uses voice telecommunication to a receiving ATC authority to extend the activation of the Control Zone past the specified finish time in accordance with subsection (3).

 (3) For subsection (2):

(a) the activation extension must:

 (i) be by voice communication (voice extension) in respect of RAAF aircraft only; and

 (ii) be authorised by me in an instrument of authorisation; and

 (iii) occur not less than 10 minutes before the period of activation of the relevant Class C Control Zone expires as provided for under Schedule 5 (the Scheduled activation period); and

 (iv) be for not more than 15 minutes in duration after the end of the Scheduled activation period; and

(b) the Controlling Authority must:

 (i) be the Department of Defence – RAAF; and

 (ii) only use voice extension because a RAAF aircraft is overdue to arrive and land in the relevant Class C Control Zone; and

 (iii) before voice extension occurs, make a broadcast on the relevant Class C Control Zone frequency to alert other aircraft of the proposed voice extension; and

 (iv) comply with any direction as to safety, issued under regulation 11.245 of the Civil Aviation Safety Regulations 1998; and

(c) the Controlling Authority must, as soon as practicable after voice extension, notify CASA in writing:

 (i) that the voice extension has occurred; and

 (ii) when, and for what relevant Class C Control Zone, the voice extension occurred; and
