Traffic Advisory System
It takes two antennas to See the whole picture.
Dual antenna traffic systems simply perform better.
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 SkyTrax600 Series, Avidyne offers four different dual-antenna TAS systems, tailored for the type of aircraft you fly. These feature-rich, affordable SkyTrax600 series systems are fully TSO certified and fully ADS-B upgradeable, surpassing the performance capabilities of many higher-cost traffic systems and setting a new standard for active-surveillance traffic capability and affordability.
Active-surveillance is vital for traffic systems to provide a full measure of safety—in busy terminal areas as well as in non-radar airspace.
Avidyne’s SkyTrax600 series systems detect and actively interrogate other aircraft transponders within range, display the surrounding traffic on a host of compatible display systems, and provide audible and visual alerts in the event of a potential traffic conflict. All SkyTrax600 series systems provide real-time traffic monitoring and advisories, are not radar-coverage limited, and operate independent of ground-based systems.
And with over 10,000 Traffic systems now in service, Avidyne’s SkyTrax600 Series lets you fly with confidence, knowing you have a proven, accurate, and active-surveillance traffic system.
SkyTrax600 systems provide traffic advisories by calculating range, bearing, and altitude of intruder aircraft relative to the host aircraft, and provide a graphical overlay view and traffic depiction with TCAS symbology on display systems from over 15 different manufacturers including Avidyne’s Entegra Release 9 and EX-Series MFDs, Garmin’s G1000 and 400/500-Series, and displays from Honeywell, Aspen, Collins, Chelton, Sandel, Avalex, and many others.
Avidyne’s ATD150 ‘half 3-ATI’ Digital Display provides control and display functionality that can be used independently or with a multifunction display. The ATD150 adds a built-in Mute/Update, Approach Mode switch, and an Altitude Alerter function, and provides a compact alternative for displaying traffic threats when panel space is at a premium.
Avidyne’s SkyTrax600 Series systems include four models, designed for your specific aircraft needs:
SkyTrax600 Recommended for entry-level, single-engine piston aircraft, the SkyTrax600 features a 7nm range, a 3,500-foot vertical separation maximum and 18,500-foot service ceiling.
TAS605 Recommended for mid-performance aircraft and rotorcraft, the TAS605 features a 13nm range, a 5,500-foot vertical separation maximum and a 55,000-foot service ceiling. It accepts Arinc 429 Heading, permitting rapid repositioning of targets during high-rate turns.
TAS615 Recommended for high-performance aircraft and rotorcraft, the TAS615 features a 17nm range, a 10,000-foot vertical separation maximum and a 55,000-foot service ceiling. It accepts Arinc 429 Heading, permitting rapid repositioning of targets during high-rate turns.
TAS620 Is our very best active traffic system, the TAS620 features a 21nm range, a 10,000-foot vertical separation maximum and a 55,000-foot service ceiling. It accepts Arinc 429 Heading, permitting rapid repositioning of targets during high-rate turns.
The SkyTrax600, TAS605, TAS615, and TAS620 are designed to meet the specific needs of each class of aircraft, providing a full 30-second decision time at a closure rate of up to 1200 knots. SkyTrax600 Series traffic systems interrogate transponders from nearby aircraft within their respective coverage volume (shown below), and provides a warning to the flight crew when the calculated time to closest approach (CPA) of any intruder and the protected area around the aircraft reaches the 30-second threshold.
The SkyTrax600 Series provides three levels of alert, so pilots can monitor traffic before it ever becomes a threat. Each of these alerts also provides an altitude separation number and may also include an Arrow pointing up or down denoting that the target is climbing or descending at a rate of 500 feet per minute or greater.
Other Traffic (OT) - Depicted as a hollow Cyan (or White) Diamond and represents traffic that is within the TAS’s surveillance area but it is beyond 6nm in range and has an altitude greater than ±1200 feet relative to your aircraft and is not an immediate threat.
Proximity Alert (PA) - Depicted as a solid Cyan (or White) Diamond on the traffic display, when the traffic is within a distance of 6nm range and its altitude is within ±1200 feet, but it is still not considered a collision threat.
Traffic Alert (TA) – Depicted as a solid Yellow Circle, a TA is displayed and an automated voice alert is activated when the calculated intercept course for altitude and direction is within 30 seconds, less than .55nm and less than ±800ft.
When a traffic conflict is eminent, pilots need the right information in real time. First-generation traffic systems only provide a “Traffic Traffic” audible alert, which then requires the pilot to look down at the display to locate the relative bearing and distance of the intruder aircraft before looking out the window.
Avidyne pioneered the concept of Heads-Up Audible Position Alerting, which verbally indicates the conflicting aircraft’s bearing, range and relative altitude for rapid visual acquisition of traffic. This automated voice alert uses the same alert terminology as Air Traffic Control:
TRAFFIC! ONE O'CLOCK! HIGH! THREE MILES!
This type of alert provides the data a pilot needs to keep his/her attention focused outside the cockpit, scanning for oncoming traffic, and it’s another example of Avidyne’s innovative approach to avionics that makes flying simpler and safer.
Standard with all SkyTrax600 Series systems, Avidyne’s patented directional top and bottom antennas provide optimum signal coverage around the host aircraft, enabling faster updates, providing enhanced performance over single antenna systems, and maximizing safety.

As the Next Generation Air Transportation System (NextGen) is implemented and with the mandate for Automatic Dependent Surveillance-Broadcast (ADS-B) on the horizon, you can fly with confidence knowing that all Avidyne SkyTrax600 Series Traffic Advisory Systems are fully upgradeable to provide RTCA DO-260B ADS-B “In” capabilities. The SkyTrax600 Series with ADS-B “In” will depict 1090ES ADS-B-equipped aircraft with better accuracy and at a further range than active-surveillance alone, plus you will continue to benefit from the active-surveillance capability of TAS for non-ADS-B aircraft and as a GPS-independent traffic awareness system. Avidyne has demonstrated itself as a proven leader in advanced avionics and continues to be at the forefront of NextGen implementation in aviation.
