Darryl, I've been looking and for most standard certificated aircraft, not experimental, it takes STC to install ADS-B equipment. A couple of STCs I have found do not list the Piper Pawnee, PA-25. Any Pawnee I have seen is registered under Restricted category. Any ideas?

Just as a heads up, here is another Mode-S/1090ES Out transponder coming with internal GPS. http://ipadpilotnews.com/2015/04/new...-b-transponder and https://www.appareo.com/aviation/ads-b-out


I thought the following excerpt from the press release was interesting, and consistent with the view that installation cost and complexity are significant factors that might advantage 1090ES over UAT even for aircraft that aren't required to carry 1090ES by rule:

"Appareo also recognized that the cost and complexity to install many of the existing ADS-B Out transponders is exceedingly high, so they focused on developing a system that would be simple for avionics shop to install. Stratus ESG connects directly to the existing belly-mounted transponder antenna and also includes a WAAS GPS antenna. For typical single-engine piston aircraft, Stratus ESG will require approximately half the installation time as compared to a remote-mounted 978 Mhz UAT ADS-B Out system."
