Garmin has devised a stand-alone automatic dependent surveillance-broadcast (ADS-B) system that satisfies global ADS-B requirements, yet leverages existing avionics equipment to alleviate the need for expensive flight management system and cockpit display upgrades.
Automatic dependent surveillance-broadcast
Nav Canada, UK NATS and Air France said they have demonstrated that aircraft can safely change their flight profiles to more efficiently cross North Atlantic airspace. The so-called Engage II project will lead to “significant changes” in oceanic procedures, Nav Canada said October 17.
ADS-B is without question a promising solution to the many safety, capacity and other suboptimal characteristics of today’s air traffic management system. Moreover, most observers agree that ADS-B will be one of the essential keys to America’s NextGen air traffic control system and comparable programs worldwide. All that is a given. Unfortunately, its introduction appears to be off to a rocky start.
The Federal Aviation Administration will not relent from requiring operators in the U.S. to equip their aircraft for automatic dependent surveillance-broadcast (ADS-B) by 2020, the agency’s deputy administrator Michael Whitaker told an industry-government committee. The ADS-B equipage mandate is the next major milestone of the agency’s NextGen ATC modernization effort.
The Aireon Aircraft Locating and Emergency Response Tracking (Aireon Alert) network, a free service expected to be rolled out in 2017, will allow rescue agencies to request the location and last flight track of any 1090 MHz ADS-B-equipped aircraft anywhere in the world, including remote or oceanic regions not covered by ATC surveillance.
Satellite-based surveillance developer Aireon will provide a free emergency tracking system for aircraft when the satellite constellation it will use is launched and operating, as expected, in 2017. Aireon announced the service on September 22, saying the disappearance of Malaysia Airlines Flight 370 earlier this year makes global emergency tracking “essential.”
As more aircraft equip with ADS-B out capability, which broadcasts position, velocity, altitude and other information in unencrypted formats on easily received frequencies, business aircraft operators are concerned about whether they can continue blocking their aircraft from display on flight-tracking websites.
The FAA is moving ahead with a plan to expand the services offered by Houston Center in the Gulf of Mexico by September 2016. As part of the plan, the FAA will install three more ADS-B radios in Mexico to enhance surveillance over the Gulf with a 60- to 80-nm coverage overlap between Houston Flight Information Region and Merida and Monterrey ACC airspace.
As more aircraft equip with ADS-B OUT–which broadcasts position, velocity, altitude and other information in unencrypted formats on easily received frequencies–business aircraft operators are concerned about whether they can continue blocking their aircraft from display on flight-tracking websites. While the FAA offers a way for operators to request blocking of particular aircraft from FAA radar data feeds, there currently is no physical means to block reception of mode-S transponder or ADS-B signals by a simple receiver.
Europe has delayed the mandate for ADS-B out equipage in its airspace. The earliest ADS-B out requirement in Europe was Jan. 8, 2015, for new aircraft, with retrofit installations due Dec. 7, 2017. The new dates are June 8, 2016, for new aircraft and June 7, 2020, for retrofit.
