Yesterday, we introduced the GTS 825 Traffic Advisory System (TAS) and the GTS 855 Traffic Alert and Collision Avoidance System (TCAS I). These new aviation traffic systems feature improved performance, each offering 400 watts of transmit power, and 40 and 80 nautical miles of interrogation range, respectively. On top of that, the current GTS 800 TAS system was validated for a range of up to 22 nautical miles, making Garmin's line of active traffic systems the best performing traffic systems for their class and price point.
So as we start preparing for NextGen airspace and equip our aircraft with ADS-B technology, why do we need active traffic systems?
An active traffic system is just as important today (while everyone begins to equip with ADS-B) as it will be after 2020 because it is the only way to ensure detection of other transponder-equipped aircraft. Even after everyone has equipped with ADS-B technology, active traffic systems will continue to detect other transponder-equipped aircraft, even in situations where ADS-B will not. Some of these situations include detecting aircraft that may not be required to equip with ADS-B, detecting traffic while flying at low altitudes outside of the range of an ADS-B ground station, or detecting traffic while flying outside of the U.S.
For the best traffic and ADS-B solution, consider pairing an active traffic system with a GDL 88 datalink. Together, these products will correlate all traffic sources (other transponder equipped aircraft as well as ADS-B equipped aircraft), provide subscription-free weather, and meet the requirements for ADS-B out for aircraft flying below 18,000 feet.
