To add your own flights, swap a/c and save the flight, then edit it so that "Start on ground=FALSE" so you don't materialise in the water behind the ship. That is from memory, but it's something like that!
Others are more expert on this than me, but as a complete carrier addict, trying to start a flight with your chosen aircraft on the deck of a moving (i.e., AI based, not scenery blg based) carrier in FSX has always been a hit or miss affair. I have some saved flights from the payware SDB Big E and somwhere else for Javier's Nimitz class, and some of these I have modded or set up on my own. However, more often than not after "load flight" the carrier is missing and the plane is rapidly dropping vertically into the drink. I have also however become quick on the draw using "slew" and "pause" and will then call up a boat in AI Carriers2 (Shift + J) on that spot and then elevate the plane using slew to deck level (it often then plops down a few feet on the deck after releasing slew but with out a crash). Then I give a sigh of relief and get engines turning and wings folding and cats lined up and all that good carrier stuff. But it is a bit of procedure.
