I just noticed that my CVP's always seem to have 5 readiness. How can you get/keep your CVP's at 10 readiness? I tried letting them sit on the CV for a turn, tried letting them launch then sit in the air for a turn. Nothing seems to work. Anyone know?

When an aircraft takes off it has low efficiency during that turn to represent their vulnerability on low altitude and speed.

It should recover to maximum efficiency the next turn. However this depends on if you have enough air supply available to maintain your aircraft. If you have too many aircraft deployed for your carriers/airfields to support, they will suffer efficiency penalties.

Holding space bar will display the supply state, the numbers over airfields & carriers relate to air supply.

Thanks for the answer, I never noticed this with my CV's before. But one problem(?) seems to be that the number over the CV has a blue anchor next to it, so that seems to indicate it's not air supply. I know from your answer that it is but this doesn't seem to be intuitive in the game for the player.

EDIT: I just realized that maybe the blue anchor is the CV unit type since it's next to CV strength and not related to supply....meaning the CV itself counts against naval command limit.

The unit plate indicates the Command Points/Supply type and cost of that unit. So a carrier is naval type of course and requires naval CP (ships don't require supply so there is no "naval supply"). The big numbers in the center of the hex is the supply output of the hex or unit on that hex. These are not related to what's in the unit plate (CV provide air supply not naval supply, other ships provide (coastal) land supply not naval supply).
