Discussion paper - Voluntary fitment of ADS-B technology in VFR aircraft (DP 1701AS)

Closed 23 Feb 2018

Opened 15 Dec 2017


Automatic dependent surveillance–broadcast (ADS-B) is a technology that enables an aircraft to be detected by air traffic control and aircraft systems. It is mandated for all aircraft operating under the instrument flight rules (IFR).  

Australia maintains an extensive ADS-B ground receiver network that enables a surveillance environment for air traffic services and enhances search and rescue capability. ADS-B receiver technology (ADS-B IN) is also available and provides an in-cockpit graphical presentation of ADS-B information from surrounding aircraft and, depending on the particular equipment, can provide visual or aural alerts about potential collisions.

CASA hopes that by exploring ADS-B compatible technologies, a safe and effective solution may be available at a reduced cost to allow for greater participation within the ADS-B system.

Why We Are Consulting

This discussion paper explores ways to increase the voluntary fitment rate across Australia's fleet of aircraft that operate under the VFR. This could be done by allowing greater choice of ADS-B technologies to be considered 'fit for purpose'. While the discussion paper focuses on the ADS-B OUT component, we believe the ideal end state is where the maximum number of both VFR and IFR aircraft are fitted with ADS-B OUT and ADS-B IN equipment.

We would like to hear from industry stakeholders, particularly avionics installers and manufacturers, about types of ADS-B equipment that would meet an acceptable standard, and if other technical standards exist that should be considered as the minimum.

We would also like to hear from the broader VFR community to gain an understanding of the interest in, and likely uptake of, these products, if they are made readily available.

What Happens Next

CASA will analyse the results of this survey to assist with a decision about pursuing technical standards and equipment types suitable for use in VFR aircraft. Based on the input from industry, CASA may develop proposals on new equipment standards for consultation. Any rule change required would be considered by the Aviation Safety Advisory Panel (ASAP) and broader industry through a notice of proposed rule making (NPRM).
