1. Download a ship like this one here: http://forums.bistudio.com/showthread.php?158772-Big-PHYSx-compatible-ship-LCS-2-technological-demonstrator [^]
2. Place a fixed wing aircraft on the ships deck and test. Then give the ship a waypoint and test again with the ship moving.
There is also a repro mission below that uses the LCS from the link above.
