Ok thanks,
so then if the carrier is damaged or destroyed then plane is awarded 1 space to find a suitable landing space else lost?
That’s correct.
Can a Trprt escorted by a DD move into a SZ with an enemy Sub during CombatMove and load the Trprt and continue on it’s way to conduct an Amphib attack ?
Or does the Sub make the SZ hostile preventing this ?
Thanks

The answer is in the same paragraph you posted. A transport does not need any warships to LOAD a unit in Combat Movement. It just needs a warship to UNLOAD for an amphibious assault if there is a lone submarine present.
The key is the sea zone is friendly if there is just a submarine there when you loaded as per the last sentence below.
