I think YOU have missed the point.
Nobody is denying that ADSB and CDTI are great pieces of kit, however, NAS is on the doorstep!!!! When, exactly, is the ADSB fit out? Get it?
It is patently stupid to change the airspace model now , and say that it will all be OK when everyone gets some mythical ADSB fit out at some time in the future. If you want to link NAS to ADSB fitout, then campaign for that. That isn't currently the case. The NASIG can't even tell you what the final version of what they are implementing will look like. Doesn't this bother you?
