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 TAS600 Series, Avidyne offers four different dual-antenna TAS systems, tailored for the type of aircraft you fly. These feature-rich, affordable TAS600 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 TAS600 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 TAS600 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 TAS600 Series lets you fly with confidence, knowing you have a proven, accurate, and active-surveillance traffic system.
TAS600 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 TAS600 Series systems include four models, designed for your specific aircraft needs:
|Model No.||Recommended for|
|SkyTrax 600 (TAS600)||Entry-level, single-engine piston aircraft, the TAS600 features a 7nm range, a 3,500-foot vertical separation maximum and 18,500-foot service ceiling.|
|SkyTrax 605 (TAS605)||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.|
|SkyTrax 615 (TAS615)||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.|
|SkyTrax 620 (TAS620)||Avidyne's 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 TAS600, 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. TAS600 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 TAS600 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 alertTraffic 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.
Standard with all TAS600 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.
