Blip,
I assume you cannot pass a CAA Class 1 due to your eyesight, which is why you are going the FAA route. I too have considered doing the same due to my eyesight being too poor to pass the CAA Class 1. However, am I right in thinking that even with an FAA ATPL I would still have to pass a CAA Class 1 in order to be employed by a UK airline? I'm sure I read somewhere a few years back that there was a route into a UK airline with an FAA ATPL for people who had poor eyesight, but I can't remember where it was. I'm hoping I didn't dream it...
