for carriers try here
http://www.taskforcefsx.com/aicarriers.html

the ai carriers 2 allow's you to place carriers like the Nimitz and battle ships directly in front off you
by using the tool provided

this is a good tool if you just want landings and take offs in random places you just can't start from one

one note though the carriers do not record in fs recorder and dose not  save position if you land on one and save flight

you would have to make your own ai route up for that
