Its actualy up to you man, i have 5 Fighters in my CV, the CV has 9 deck space. I load up 3 planes for each of the 3 first pilots, once i launched them, i start loading 3 planes for the last 2 pilots, after i launched the last 2 squads, i repeat the secuence. Makes it easy to fighter camp a lame CV that spamms bombers or doesnt actualy use hes FPs much, or even to blind the enemy, each battle i send my FPs to intercept the first wave of scouts in the sector i am, so the enemy keeps blind till the CV sends higher level piltos against mine. You just need to find the combination that fits you
