The rumour around is that at the last moment, they are going to follow the AOPA request and delay the mandate until after that of the USA. In the meantime, lots of small firms are borrowing money to fit the ADS-B, even though they claim there is no measurable saving.
Just my luck as I'm getting a Part21M MOD developed.
Anywho - Dick, there will be a saving! The saving will be in AsAs coffers. What, with ADSB, TCAS2, EGPWS, WAAS approaches/departures, etc, the need to pay for controllers with experience, attention to detail and a good analytical mind will disappear - the aircraft will be almost flying and segregating themselves.
Nevermind how this will benefit GA - as long as the big tails, CAsA and AsA are catered for.
