Those are the minimum values of air power that you need to achieve the respective stat. You get air power by equipping fighters or fighter-bombers on your carriers, or seaplane bombers on your BBV/CAV.

Air Parity (no one does artillery spotting), Air Superiority (you do artillery spotting on the enemy) or Air Supremacy (you do artillery spotting on the enemy and most likely cripple all their bombing squads).
