Why upgrade? ADSB Out systems to replace radar across aircraft

Automatic Dependent Surveillance Broadcast (ADSB) Out systems broadcast the exact position, altitude, velocity and flight ID of an aircraft to air traffic control and other ADSB capable aircraft.

Using both satellite (GPS) and ground-based surveillance systems, ADSB is expected to supersede radar. And for good reason: ADSB Out is superior both in speed and reach, transmitting unobstructed data in real time.

Adoption of ADSB technology has already been mandated in aircraft flying under Australian instrument flight rules (IFR). This legislation improves air-traffic congestion related safety and, specifically, the dangers of flying too close to — or colliding with — another aircraft.

A fundamental concept in flight safety, the ‘see and avoid’ method of avoiding collision relies on effective visual scanning. Superseding radar technology, ADSB takes human error out the picture when it comes to judging airspace visibility.

While vigilance remains an essential part of your flying routine, installing an ADSB transponder is a preventative upgrade that improves the safety of our busy open skies. Expected to become mandatory for visual flight rules (VFR) aircraft owners in time, the Australian Transport Safety Bureau (ATSB) recommends applying for local ADSB rebates while you can.

In a recent media release, ATSB Chief Commissioner Angus Mitchell noted, ‘The use of ADSB with a cockpit display or electronic flight bag application showing traffic information greatly improves a pilot’s situational awareness and enhances the safety of their flight.’

For New Zealanders, ADSB Out extended squitter (ES) systems have been required in all transponder-mandatory controlled airspace since 31 December 2022.

Improving visibility across Australia’s open skies, Microair’s new ADSB transponder ensures light aircraft can be seen at all times. Designed and manufactured in Queensland, the T2000ADSB is a lightweight transponder — easy to install and with low power requirements — that is eligible for ADSB rebate programs in both Australia and New Zealand.

The Australian Government’s AU$30 million ADSB Rebate Program and NZ Government’s NZ$12.5 million ADSB Grant Scheme support owners of recreational aircraft in upgrading to this essential technology.

Microair has been challenging the status quo with their world-class avionics solutions for over 25 years, helping your dreams take flight. Find out more about how to upgrade your light aircraft to Microair’s new T2000ADSB Transponder and take advantage of government rebates at
