WWW,
I'm all for keeping the cost down. Lets have Mode S for GA and lets get the CAA to subisidise it and levy a special quarter percent tax on every airline ticket for a year. That would cover it all easily.
Hello!!!!! Reality check please!!!
Do you honestly think this is ever going to happen? From what I know of the CAA, the airlines, competition, the travelling public, attitudes to GA, plus life generally, it ain't - not never no how. Nice idea, but...let's be realistic here.
