“Midair collisions statistics are revealing,” said Avidyne COO Patrick Herguth during the company’s press conference at Sun ’n Fun 2013 (Booth C-71). “Fifty-nine percent of midairs happen near the airport; and 54 percent are between aircraft flying in the same direction.” Herguth was citing a 10-year-long study published by researchers at Massachusetts Institute of Technology in Cambridge, Mass.
Automatic dependent surveillance-broadcast
Sagetech’s Clarity portable ADS-B receiver, which began shipping on March 27, is on display this week at the company’s booth (No. D-028) at the Sun ’n Fun Fly-in in Lakeland, Fla. The device comes in two versions: a baseline Clarity unit that receives ADS-B signals on both 978 and 1090 MHz and the Clarity SV with both frequencies and an attitude heading reference system (AHRS), which can be used to display attitude on compatible devices and applications.
Dassault Falcon has received EASA approval for a supplemental type certificate to install ADS-B Out (automatic dependent surveillance-broadcast out) on Falcon 50EXs and classic Falcon 2000s equipped with Pro Line 4 avionics. With this STC, Falcon operators can take advantage of the safety and operational improvements of the new technology before the mandated compliance dates set by airworthiness authorities. The EASA certification follows FAA approval, which was received for both aircraft within the past year.
Garmin’s GDL 39 portable ADS-B receiver offers a simple solution for pilots who want to receive free weather and traffic information without a lot of complication. The GDL 39 sells for $799 and receives both types of ADS-B signal that are a unique feature of the U.S. ADS-B landscape. Not all portable ADS-B receivers are dual-band; some receive only the frequency that provides free weather information and certain traffic targets.
The Department of Transportation’s Office of the Inspector General (IG) announced on January 23 that it is initiating an audit of the FAA’s ADS-B “information security controls.” While some concerns about insecurity of ADS-B signals have surfaced, it is not known if these concerns drove the decision to require the audit. The audit itself stems from a requirement in the FAA Modernization and Reform Act of 2012.
Unmanned aircraft system (UAS) operators in the U.S. would have to file and fly instrument flight plans and equip their aircraft for position reporting with transponders and automatic dependent surveillance-broadcast Out (ADS-B Out) transmissions based on GPS.
The FAA granted TSO authorization to Garmin’s GDL 88 ADS-B solution, designed to bring ADS-B out and in capability to Part 23 aircraft flying below 18,000 feet to meet the Jan. 1, 2020 ADS-B out mandate. The GDL 88 receives on both ADS-B frequencies, 978 and 1090 mHz, allowing display of most traffic types as well as FAA-generated traffic feeds. The GDL 88 also includes Garmin’s TargetTrend relative motion technology to help pilots “visualize the trend of traffic threats as it relates to their aircraft,” according to Garmin.
Accord Technology’s NexNav mini GPS receiver is now available to provide the GPS solution for Trig’s TT31 ADS-B out transponder. The combination of the NexNav mini and Trig TT31 meets the FAA’s 2020 ADS-B out mandate, which requires a GPS source that meets specific accuracy requirements (TSO-C145c Class Beta 1). The TT31 retails for $3,349 and with the NexNav mini is installable under an approved model list in a variety of aircraft. The NexNav mini costs $5,775. Flight-testing was done in a Mooney M20.
Pilots who operate ADS-B-equipped aircraft in any of seven U.S. terminal airspace regions can now take advantage of free air traffic advisories and weather information. The areas include Fairbanks (FAI) in Alaska; Lansing (LAN) in Michigan; Moses Lake (MWH), Pasco (PSC) and Yakima (YKM) in Washington state; as well as Waterloo (ALO) in Iowa; and Youngstown (YNG) in Ohio.
As with civil aviation operators, the U.S. Department of Defense (DOD) must ready its aircraft fleet to comply with fast-approaching mandates to operate in the future global airspace system. Failure to meet those requirements will prevent operators from being able to take advantage of preferential routes and altitudes that will be available to properly equipped aircraft.
