To answer:
1) Less bureauocracy. Does anyone really know what JAR is all about?
2) No. As above re too much bureaocracy (I'll spell it right one day)
3)No- France. Also pan European licence may be one thing, but getting a job in that country due to social/political reasons may be another (except the UK - we'd quite happily employ others over UK nationals)
4)Yes. Why have a great big bur..etc to sort out licencing and training for someone to fly in uncontrolled airspace a couple of times a month. Professional licencing- OK, but for PPl's it's a waste of time & money.
5)Don't know. From the flying club world (where I was at the time) I think that only a few people CFI's etc repiled to anything that was sent out. They had more important things to do.
