Dual-Antenna TAS600 Sets 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 TAS600 series, Avidyne offers three different dual-antenna TAS systems, tailored for the type of aircraft you fly. These feature-rich, value-priced TAS600 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. ™

The Most Display Options

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 and EX-Series MFDs, Garmin's G1000 and 400/500-series, and displays from Honeywell, Collins, Chelton, Sandel, Avalex and others.

Active Innovation

Resulting from the merger with Ryan International, an industry innovator in the field of active-surveillance traffic systems, Avidyne’s new TAS600-series, with Ryan Active Surveillance™ (RAS) technology, detects and actively interrogates other aircraft transponders within range, displays the surrounding traffic on a host of compatible display systems, and provides audible alerts in the event of a potential traffic conflict. Active interrogation gives the precise location of nearby aircraft, providing real-time traffic information with no delay. Having an active traffic system is vital to providing a full measure of safety, in busy terminal areas as well as in non-radar airspace. All TAS600 systems provide real-time traffic monitoring and advisories. The TAS600 system is not radar-coverage limited, and is not dependent on ground-based systems.

Curved Paths

When flying GPS approaches, the EX500’s large display clearly shows curved flight path segments when provided by the GPS, including DME arcs, Holding Patterns and Procedure Turns, overlaid with traffic, terrain, weather, airports and runway diagrams. And with Avidyne’s CMax™ Electronic Charts, the EX500 really takes the guess work out of shooting instrument approaches.

Avidyne’s TAS600 series includes different models, designed for your specific aircraft needs:

TAS600 Recommended for 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. TAS610 Recommended for mid-performance aircraft and rotorcraft, the TAS610 features a 12nm range, a 3,500-foot vertical separation maximum and a 25,000-foot service ceiling. It accepts Arinc 429 Heading, permitting rapid repositioning of targets during high-rate turns.

The TAS600 and TAS610 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.

Seeing the Big Picture

The TAS600 provides three levels of alert, so pilots can monitor traffic before it ever becomes a threat.

The first level of alert is indicated on the display as an open diamond shape, with the altitude separation indicated between the host and threat aircraft and an arrow indicating if the threat aircraft is climbing, descending, or at the same altitude. This is referred to as Other Traffic (OT). OT is not an immediate threat but is within the surveillance area and the pilot should be aware of existing traffic.

The second level of alert is Proximity Alert (PA) and is displayed with the same information as OT, with the exception that the diamond shape is now a solid shape on the traffic display.

Traffic with a calculated intercept course for altitude and direction become a Traffic Alert (TA). When a TA is encountered, the intruder traffic is indicated as a yellow circle.

Heads-Up Audible Position Alerting™

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’s Heads-Up Audible Position Alerting™ 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! Two miles.” This type of alert provides the data a pilot needs to keep his attention focused outside the cockpit, scanning for oncoming traffic.

Top and Bottom Antennas

Standard with all TAS600 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.
