Ian,
Average time for the IFR is around 55-60 hours, I think.
I know a few people who did it in less than 40. Depends on where and how they did the course.
Monkeypitch,
I don't (can't!) fly or teach in jets. My only commercial flights are as a passenger, and most of the aircraft I fly are 30yrs old or more. I just think that 15 hours of training in enough to instil a false confidence.
I have to admit that I've never flown in the UK or Europe, other than some VFR. However, from what I can see, the FAA system is certainly better, not because its "American" but because it just makes more sense.
Can someone explain the benefits of those strange QFE/QNE/QNH altimeter settings?, or why transition level should vary? Over complicates what should be a pretty straightforward activity! There is nothing special about the weather to justify it. East Coast USA weather, especially in Winter, is just as bad.
General Aviation in Europe is just not as accessible, because some see it as only for the elite, and commoners should not be allowed in!
15K+ for an IR is robbery. Four times the price I paid for what seems to be a lot more training than a UK/Europe ticket.
The IMC rating has advantages, but I defy anyone to say that using it as more than a 'get-out-of-trouble' tool is safe!
