Of course you'll need to decide if you want to. The game engine doesn't deal with ship's air operations at all, it will just spawn planes. The BBs won't have to ever stop to recover their planes, etc.
As a result, If I put any at all, I'd tend to reduce the numbers from what was really carried. Perhaps one plane. I might be inclined to delete one of the planes on a cat in the eqp, too, since it will be in the air
