busy deck 003 should be able to do a simultaneous launch and recovery
Not only on the deck but also in the air. It is no good idea to have recovery and departures at the same time arround an military airfield when approaching with break over the field and traffic patterns.Nah mate. You don't do simultaneous launches and recovery unless you want to lose some air-frames and pilots and cause a disaster on the deck.
many many reason why this is a bad idea. Least of all, aircraft taking off are typically flying into the wind for better lift, taking off from the opposite direction would cause issues.Why not launch in multiple directions if you have a flat deck? Several to the bow, lesser to the stern?
