While having a chat with friends in regards to ADSB vs GPS capable of making approaches one of the guys brought up that the GPS receivers used for ADSB are good enough to let everyone else know where you are (VFR or IFR, and will be the sole means for ATC to locate you in some areas after 2020) yet it is NOT good enough to let YOU know where you are in order to fly enroute or to shoot approaches.
So outside of the ole answer of they can't allow it because Garmin would be pi$$ed for all the money they had to spend to certify the GTN650 while some experimental joe schmoe is using a $500 gps to do the same thing, what exactly is the reasoning?
My understanding of the approved GPS recievers for ADSB is they can exclude satellites if they are giving bad info already so that checks that box. They are WAAS, so there's another box. The only thing I can see that is missing is a database that cannot be modified by the user. I'm sure Garmin can easily program that for my G3X (can vs would). Of course last but not least would be for the governing agencies to change their rules to allow for such a crazy thing to happen.
So again I must ask, why is it good enough for you to know where I'm at but not good enough for me to know where I'm at?
