Do you have any web references for the ADS-B, I see that the Ryan TCAD equipment is upgradable to include it but I dont know what it is ?
Ryan TCAD is designed to be a GA version of TCAD, the ones I have seen are not full TCAS boxes as they lacked the datalink capability for aircraft to communicate and come up with advisories (hence TCADetection not TCAS).
Their web site is
http://www.ryan-tcad.com/products/tcad/Main.html the high end boxes can interface with Eventide ARGUS displays, Avidine Flightmax Flight Situation Display, and the Garmin 400/420/430/530 GPS systems to display the aircraft threats.
They claim their systems have been installed in aircraft ranging from kitfoxes, cessnas, commuter turboprops (1900, Merlin, Metro III, Saab 340), corpoate jets (Citation, Lear, Hawker, IAI, Saberliner) to B737's, they have been around for years.
