To increase the surveillance separation service and enhance safety, Airservices Australia is undertaking a twelve-month trial of Class E airspace steps at Ayers Rock to 5,500ft Above Mean Sea Level (AMSL) (A055).


BACKGROUND


As part of Airservices' commitment to improving the provision of safe and innovative services through the Airspace Modernisation Program (AMP), Airservices continues to develop opportunities to enhance the level of safety and efficiency of Australian airspace. On 21 May 2020, a twelve-month trial of Class E steps to 5,500ft AMSL (A055) at Ayers Rock will be introduced, having received the approval of the Airspace Change Proposal (ACP) from the Civil Aviation Safety Authority (CASA).

The approved airspace design was finalised through comprehensive consultation with airlines, general aviation, and industry stakeholders in 2019, resulting in enhanced safety and increased surveillance separation services for Instrument Flight Rules (IFR) airspace users. The introduction of Class E airspace at A055 will facilitate Visual Flight Rules (VFR) scenic flights and regular public transport (RPT) operations. The existing scenic routes and Common Traffic Advisory Frequency (CTAF) procedures will remain in place. Consequently, IFR operating aircraft will receive an increased surveillance separation service through the availability of Automatic Dependent Surveillance Broadcast (ADS-B) at Ayers Rock.


WHAT ARE THE IMPACTS OF THIS CHANGE?


The approved airspace design shows the Class E steps as:

· A055 if the lower limit is within 25nm


· A065 if the lower limit is from 25 to 35nm


· A085 if the lower limit is from 35 to 50nm


· FL115 if the lower limit is from 50 to 60nm


· FL125 if the lower limit is outside 60nm


WHAT WILL THE AIRSPACE LOOK LIKE?

WHAT ARE THE BENEFITS TO AIRSPACE USERS?


The expected benefits of introducing Class E airspace at Ayers Rock include:


· Enhanced safety through the introduction of a surveillance separation service from air traffic control.


· By lowering the base of Class E airspace, surveillance separation in the area is increased down to 5,500ft (AMSL).


· Airspace users could benefit from the fitment of ADS-B avionics to receive a separation service by air traffic control.


WHEN WILL THIS CHANGE START?

The twelve-month trial will commence on Thursday, 21 May 2020.


HOW DO I ASK QUESTIONS AND PROVIDE FEEDBACK ON THIS CHANGE?

Please refer to the Q&A section below to submit your question. Airservices will be providing two opportunities for the aviation industry to provide feedback on the trial at both six and 11 months. This page will be updated in November 2020 and April 2021 to facilitate a feedback function. Our industry stakeholders will be contacted and reminded about this closer to the date.
