It means that in 10 years time, sport aviation might be only the distant memory of a few old people sitting in their nursing homes.
I am afraid that is a lot closer to the truth than many would admit, but equally the same will happen to the old farts inside the CAA
The only difference is that they will have a much better pension than you...
I think Mode C should have been made mandatory, in many/most places, years ago. The problem with GA is that everything is made into a massive fight, often backed up by highlyemotive and false arguments (like the big brother radar surveillance stuff - never technically feasible). Every time this bogus stuff gets used, the people in power just take the p1ss.
Mode S is not the end of the world; many people operating 30 year old Cesspits spend twice the GTX330 installation cost on every Annual. If your plane has no way to carry a Mode S XP then by all means fight it but for everybody else it is now a lost battle.
