Rulebook (Europe 1940.2, page 13) has it:
"However, units can’t end their movement in friendly spaces during the Combat Move phase except in four instances.
…
from a friendly sea zone, as well as sea and/or air units that
may be needed to support it in the case that defending air
units are scrambled (see “Scramble,” page 16).
"
@nzcamel said in Protecting the transports with aircraft, in an amphibious landing, from scrambles.:
@aequitas-et-veritas they aren’t being sent to join a certain combat. They are staying with the fleet (with no enemy ships present) not fighting in the landing battle. Are you sure they are allowed to move in the combat step?
… same rulebook, page 32:
“Carrier aircraft move independently of the carrier on their own turn. They move along with the carrier on its turn if they belong to different powers. On the air units’ turn, they launch before the carrier moves, even if they are not leaving the sea zone themselves.”
So in case the attacking power brings its fighters to the sea zone in question (with the fleet or not) during combat move phase they will fight against possibly scrambling units.
Only fighters belonging to friendly powers remain as cargo on the carrier.
