If you goto the relative spot next to the CV where you spawn you can get a successful landing. I don't know if any enemy in the vicinity changes that. Same thing with spawn point, it might have something to do with an enemy being near the spawn, the base, or maybe even whether the Vh is up of down. Also if a runway of that field is near the shoreline beach your PT as near as you can to the runway, I've gotten secessful landings using that technique.
I guess I'm in the same boat not knowing the exact yes/no situation required for a good landing.
