CASA issues NPMR for frequency use at low level in Class G airspace

31 October, 2017

Australia's Civil Aviation Safety Authority (CASA) announced (31-Oct-2017) a notice of proposed rulemaking (NPRM) for frequency use at low level in Class G airspace will be available for public consultation by the end of 2017. Class G airspace is uncontrolled, with neither IFR and VFR aircraft permitted or required to seek ATC clearance. The policy being developed for endorsement by the Aviation Safety Advisory Panel takes into account the preferences received from consultation on the 'Frequency Use at Low Level in Class G Airspace' discussion paper along with future airspace considerations. CASA intends to propose a change to the current advice in the AIP that will require pilots to monitor MULTICOM 126.7 below 5000ft wherever there is no discrete frequency or broadcast area. The proposed solution will also reflect the strong preference received during consultation for keeping ATC transmissions separate from general transmissions whilst retaining the safety and situational awareness benefits of alerted see-and-avoid.
