What I do is set the carrier speed to 30 kts, ...and then stagger the flights (sections or elements) in 1/2 nm intervals ahead of the carrier along it's path, ...with the first one to spawn at minute=1, the second at minute=2, ...etc...
The carrier will move underneath the launch position and the AC materialize low over the flight deck at minimum speed (set spawn to min. alt and speed) and looks like a deck T.O.
You can wait 5 minutes before the companion carrier begins its launch cycle, ...just locate the first element starting at 2.5 nm along the route and then the following ones every 0.5 nm after it.
If you spawn at minute=0 and launch at minute=1, ...that gives you a few minutes to get in place before the show starts.
