Airservices has revised its proposal to lower the base of Class E airspace, based on industry feedback received. The refined design is now proposed to lower the base of Class E airspace along the east coast to be 4,500ft, 6,500ft or 8,500ft AMSL depending on terrain.

The issue

Airservices would like to thank all airspace users and aviation industry stakeholders that provided feedback on the original proposal to lower the base of Class E airspace along the east coast of Australia.

During the initial consultation period of 20 January to 15 February 2021, we received over 1,000 responses including significant feedback from general aviation operators around safety, risk, operational needs, aircraft fitment, cost/benefit and operator workload considerations.

Redesign to address industry feedback

Based on industry feedback received, we have refined the design and propose the base level of Class E airspace along the east coast to be 4,500ft, 6,500ft or 8,500ft Above Mean Sea Level (AMSL) depending on terrain.

The refined design seeks to:

  • improve safety of Instrument Flight Rules (IFR) operations by providing a more effective risk control against conflict/collision risk than pilot-separation
  • minimise adverse impact on the needs of airspace users, particularly general aviation operators, that will continue to require access to Class G airspace, including those without necessary transponder or radio equipment
  • provide more levels to cater for safety of operations outside proposed Class E airspace to avoid terrain (including a minimum of 1,360ft of Class G airspace between terrain and the base of Class E airspace in mountainous areas) and cope with convective weather
  • remove potential for confusion regarding the operation of aircraft in Class E or Class G airspace, and which frequency the pilot should be on, by referencing airspace levels to AMSL
  • reduce the impact of frequency transfer during critical high-workload phases of flight between area frequency and Common Traffic Advisory Frequency (CTAF) while transiting across Class E and Class G airspace.
