In answer to CYYZGUY,

It's not bad here in the UK, but there is still a way to go, Flybe are notoriously invisible on the map at present, the majority of the fleet being Dash 8's, ( surely they will have to start soon, although they seem to have a lot of comings and goings within the fleet ).

And the Canadair CRJ family of aircraft are few and far between at the moment, although I have spotted one Lufthansa regional a/c with ads-b, so they have started upgrading.

MLAT will become less important as we approach 2020, USAF KC10s are now being upgraded, and I am sure the other heavies will have to follow suit, and GA aviation seems to be taking up ads-b increasingly as new options start to appear.

And as if to confirm that, just flown over here with full ADSB showing on the map :
