thanks for the replies!
I have an FAA IR already so have been looking into conversion courses... still not cheap! The plan was to get my IR, do some offshore stuff and build up some experience before moving on to air ambulance or something else onshore. I have a bit of R22 time (just no JAA type rating) and will likely get quite a bit of time on the 206 before moving over next spring.
I'm hoping to get the IR and then return to the USA for a while, but staying here long-term isn't happening - my wife & I both want to live in the UK
I'd rather avoid resitting the exams again, but perhaps it's unavoidable at this point
