This is one of the most interesting threads I have had the pleasure of reading on this board or any other for that matter.
As a UK trained PPL of Dutch nationality I am currently training towards my IMC. All I ever want, if it would be legal, is to use the same IMC in Europe. I am not too interested in airways. I want to be able to do a let down in continental Europe legally in exactly the way I am being trained to do it in the UK. Even being able to go above on a return journey and land in the UK would already be a great help.
As this is not legal at the moment all I can practically do is gain experience once I have gained my IMC and eventually go down the FAA route.
