Global Transition to ADS-B

The implementation of Automatic Dependent Surveillance – Broadcast (ADS-B) technology is becoming more widespread as countries are establishing ADS-B mandates to enhance and extend the surveillance capabilities of their Air Traffic Control (ATC) systems.

Twelve countries have added new rules that mandate ADS-B for aircraft operating within specific regions, classes of airspace or airways. In some countries, these rules go as far as to require the aircraft operator to obtain approval from their State Registry to access the ADS-B airspace.

Other regulations create a specific benefit to operators that have equipped voluntarily. The regions where ADS-B are mandated will continue to expand, and operators should monitor for updates from their local regulatory authority.

What is ADS-B?

ADS-B replaces or supplements radar surveillance of aircraft. Aircraft equipped with an ADS-B transmitter use GPS technology to locate the position of the aircraft and then transmits identification, position, altitude and velocity information in real time. Air traffic controllers intercept this flight and traffic information services broadcast data and are able to position and separate aircraft with improved precision and timing.

ADS-B relies on a high-integrity GPS navigation source and a data link (ADS-B unit). There are several types of certified ADS-B data links, but the most common ones operate at 1090 MHz – essentially a modified Mode S transponder – or 978 MHz.

This technology consists of "ADS-B Out" and "ADS-B In." ADS-B Out is the transmission of data; ADS-B In is the reception of this information. All aircraft equipped with ADS-B can transmit data, but not all are capable of also receiving data.

Benefits of ADS-B

  • Improved situational awareness
  • Improved visibility for air traffic controller and flight crew
  • Increased safety due to more accurate position reporting
  • Greater efficiencies in handling aircraft in congested airspace
  • Additional benefits to aircraft with ADS-B In capabilities:
  • In-cockpit traffic information from other aircraft equipped with ADS-B
  • In-cockpit weather information using Universal Access Transceiver (UAT) ADS-B equipment
  • In-cockpit terrain data
  • In-cockpit flight information

Current & Future ADS-B Requirements by Country

Australia: As of June 6, 2020, ADS-B is mandatory for all IFR flights above and below FL290 operating over continental Australia. Currently, ADS-B is required for all flights operating at or above FL290 over the continent, the Arafura Sea, the Great Australian Bight, and the Bass Strait. All Australian registered aircraft operating in Classes A, B, C or E also require ADS-B.
