Aircraft owners and operators flying in the U.S. and Europe are less than two years away from being required to equip their aircraft with ADS-B Out technology. Some countries in the Asia-Pacific region already require ADS-B Out, such as Australia, with others mandating the equipment to fly at altitudes above 29,000 feet.
Since the introduction of the 2020 mandate in 2010, the FAA has addressed pricing, availability of technology, the amount of paperwork required, and a variety of other concerns with the 2020 ADS-B mandate. It has yet to comprehensively address, however, cybersecurity issues with ADS-B technology. ADS-B (automatic dependent surveillance-broadcast) uses onboard GPS sensors combined with ADS-B transceivers to broadcast aircraft position, velocity, and identification information to other aircraft and ground receivers, including air traffic control facilities.
