TAS-A Series ADS-B-capable Traffic Advisory Systems

TAS-A Series Set a New Standard

Traffic Advisory Systems (TAS), which are based on the technology originally developed for air-transport category traffic alert and collision avoidance systems (TCAS), have been available for general aviation aircraft for several years, but have been cost-prohibitive for many owner-flown aircraft. Until now.
With the new dual-antenna TAS-A Series, Avidyne offers three different TAS systems (TAS605A, TAS615A and TAS620A more...), tailored for the type of aircraft you fly. These feature-rich, value-priced TAS-A systems are fully TSO certified, surpassing the performance capabilities of many higher-cost traffic systems and setting a new standard for active-surveillance traffic capability and affordability.

Dual Antennas simply perform better

Avidyne's dual-antenna TAS-A Systems detect other aircraft sooner and more accurately, so you avoid surprises due to the shadowing effects inherent with single-antenna systems. Using top and bottom directional antennas, TAS-A systems actively interrogate other aircraft, providing timely audible and visual alerts with the precise location of conflicting traffic. The dual-antenna TAS-A Series provides full-time protection and higher performance. Because when it comes to safety, you want to see the whole picture.

About ADS-B

ADS-B, which stands for “Automatic Dependent Surveillance-Broadcast,” is a new surveillance technique for air traffic control being implemented in the United States (and other countries). With ADS-B, an appropriately-equipped aircraft determines its own position using a WAAS-capable global positioning system (GPS) and periodically broadcasts this position and other relevant information to ground stations for use by Air Traffic Control (ATC) and to other aircraft with “ADS-B In” equipment for display on compatible on-board multi-function displays. ADS-B is automatic in that no pilot or controller action is required for the information to be issued, and it is dependent on all airplanes having compatible equipment (ADS-B Out) that transmits their position and velocity information. A DS-B can be used over several different datalink technologies, but the two most discussed are Mode-S Extended Squitter (1090 ES) and Universal Access Transceivers (UAT). ADS-B provides accurate information and frequent updates to airspace users and controllers, and is intended to improve the use of airspace, reduce ceiling and visibility restrictions, improve surface surveillance, and enhance safety.

View TAS-A traffic on virtually any display

The dual-antenna TAS-A systems provide traffic advisories on the displays of more than 15 manufacturers, inculding Avidyne's Entegra, MHD and EX-Series MFDs, Garmin G1000 and 400/500-Series, Honeywell KMD250/550/850, Sandel, Chelton, Avalex, and many more...
