Hi everyone, I have been trying to sort through the maze of FAA regs with little in the way of definitive answers.
So far, all I can get after speaking with most of the current EFIS manufacturers, is that you need a WAAS certified GPS radio (e.g. GNS 430W, or GTN 650) to interface with the EFIS in order to shoot a "legal" GPS approach with vertical guidance.
All of the certified WAAS radios are very costly. I noted that there are many WAAS enabled GPS radios for boats that are significantly less expensive. Does anyone know if these units can be used for WAAS GPS information to enable a legal GPS approach?
Thanks!
Roger
