The unit, which plugs into an AC power receptacle, is about the size of an automotive radar detector and contains an integral antenna and small display. XRX tracks up to 10 aircraft at a time and displays the top three threats. Unlike TIS-based systems, which rely on ground-based radar, XRX works independently of mode-C interrogation, displaying quadrant bearing information, relative altitude and range. The display window is scalable to a maximum range of six nautical miles and altitude of ±2,500 feet. Close traffic is announced by two levels of voice alerts heard through the pilot’s headset, as well as audible beeps. The device measures 3.9 inches wide, 3.6 inches deep and 2.7 inches tall, with most of the height accounted for by the XRX’s enclosed antenna. The device sells for $1,795.
