hiya.
to tell the truth i dont know much about the 8km environment. as soon as i installed the game - pretty much - i'd found subsim and gwx: the only time ive used an 8km, and the vanilla game generally, environment was the training missions!
from what ive noticed in my current campaign, my watch officer and crew are more than capable of spotting ships before they spot me. therefore, if youre having problems, could it be time compression? my TC values for "ship spotted" and "plane spotted" are set to "1". if yours are set higher, then it could be that you missed a "spotted" message from your crew and, with the higher TC, have rapidly sailed close enough to the enemy for them to see you and take appropriate action.
i dont know for sure, but i swear ive read somewhere that your (crews or you personally) vision is generally better than the enemys; like i said, i dont know for sure.
i could be wrong. the gwx2.1 manual has loads of advice for maintaining stealth
good luck!
