So I noticed some inconsistency between the chinese and english version of this tournament rules days ago. The chinese version explicitly states that CV can carry UP TO 1 fighter pilot, and the fighter pilot must be numbered as the first squadron (e.g. your fighter pilot must be the first pilot among all pilots from the left side of your support sailor slots) for the ease of real-time identification by the referee. I'm not sure if any mod or gm will correct the english version but my friend sent a support ticket regarding this issue and was confirmed that the chinese version is the correct one. 
In case they won't correct it, if you're reading this please inform your fleet members and other participants about the mistranslation to avoid confusion during the tournament.
