I spoke to Mike Smith at Avalon. While I felt his tone was a little too high and mighty he did make some valid points on NAS and I remain happy that it isn't going to change anything for the worse.
One thing I didn't like. He really doesnt want cockpit displays in GA aircraft using ADSB. He also feels Private operators should (will end up??) pay for the unit and installation.
Now AsA have intimated that ADSB will be waaay cheaper than replacing soon to be obsolete radar heads, not to mention increasing coverage. So i hope Mr m Smith sticks to NAS and stays out of this debate, otherwise we will see another 'mandatory ELT' debacle and ADSB will falter!!!!
