I'm also interested in your opinion about the Brevet de Base that seems not to be appreciated in UK (please feel free to write an email to me about that), that could raise ideas for our next brainstormings, and maybe we could make proposals to improve it.
I asked about it because 'on the face of it' it sounded quite dangerous, but actually when you explained it didn't sound too bad...in fact the idea behind it (PPLs learning to deal with passengers) is excellent. I think it's good that we can discuss ideas like this.
Re the airways: in the UK airways are class A so no VFR flight at all (I think occasionally parachute droppers are allowed to enter but I'm not quite sure about the rules). In general no one goes into the airways without an IFR clearance. CTRs are class D and all traffic has to ask permission to enter and maintain contact with ATC at all times.
