I thought it represented ordnance. If it represented avgas, then fighters flying CAP and escort would use up these points also.

We've added an item called aircraft ordinance to each carrier. This represents aviation gas and bombs. We didn't want to have carriers run themselves out of the ability to put up CAP and search, so we only deduct 1 point from the aircraft ordinance whenever a plane launches on a strike mission (including escorts). Typical carriers have a value around 500, meaning they can launch 500 aircraft on strike missions.
As you can see, in fact this is about aviation gas consumption. CAP fighters don’t use points to avoid problems, kind of a emergency aviagas reserve, while escorts(!), TBs, DBs all using 1 point while flying strike missions. No bombs, no torps, all you have is just 500 tons of aviation gas to fuel aircraft you need in the air the most, no actual weapons.
