Just follow the instructions line by line. It looks complicated at first, but it's really quite simple once you get into it. If you download almost any of Paul Clawson's FS9 carriers you'll find a link to BGLcomp, a copy of the other program, and complete instructions on how to relocate the carrier. The software you need is Microsoft's BGLcomp and someone else's (can't recall) BGLxml. Martin How difficult depends on the carrier. Is this possible and is it difficult to do? I've always wanted a carrier a couple of miles just off Plymouth, so that I can practice my landings on.
