I read through the posts and I am not sure if the question regarding "How would ATC know you didn't have a TSO ADS-B out"
If it is in there let me appologize now, but, in my discussions with the owner of SkyGuard; The Vision Pro and all the ADS-B out devices transmit identification that can be used to verify the approval status. In short they will know you are using a non certified unit and that is ok untill 1/1/2020.
I know Don is trying to get approval but have not heard anything about his progress. I continue to have issues with dropout of the signal and have almost went to the expense of purchasing a permanent antenna. Seems lately my gps puck is not always seeing the sky well ehough to turn the transmitter on.
Anyone know if they make an extension cable for the gps puck?
