Once again, the "Voice of Reason" steps up with a clear and concise explanation of the situation. Thanks, Darryl. And thanks for trying to explain the ins and outs of ADS-B. A daunting task, made more daunting by the inherent characteristics of a Federal Bureaucracy mandating a questionable technology. Not that I am totally against it- I am in the process of installing a Trig TT22. I may also have to request a new Airworthiness Certificate, moving my glider from Standard to Experimental so I can take advantage of 2020 compliant ADS-B for one sixth the price of a Standard Category installation. Makes a lot of sense, doesn't it?
