"I suppose a ship could always consider doing something silly like turning into wind. Ashore, a pilot might even consider turning into wind himself before landing vertically."
Captains of flat deck ships often have other things to deal with as well as the landing aircraft. Within aircraft landing limits these Captains may make the WOD [Wind Over the Deck] such that it is within the aircraft limits for landing. Operational necessity - crowded seaway - other ships on collision courses or whatever can be imagined, may produce not ideal wind conditions for landing aircraft. It is even more difficult on angle deck carriers for various reasons. Here we have axial flat decks.
