I have both addons installed but I have never used the carrier...
If you want the plane just on the deck, then use this command on the planes init field:
this setPos [(getPos this select 0),(getPos this select 1),Z]
where z is the height in wich the plane will be placed... Place it high enough and you get it on the carrier
See some scripting tutorials to understand those "getpos this select 0 things, If you are interested....
