That is a theoretical load of aircraft and nor Kuznetsov neither Liaoning has seen more than 14 aircraft on board yet. Kuznetsov will never see aircraft again and Liaoning may see some day in the future her 24 aircraft. I am waiting for this moment.
If you would like to know, how many aircraft are on board an US-Navy carrier, google for pictures of quija-boards. There should be all aircraft on the table: the one on deck, in the hangar and in the air. Because the deck crew have to deal with all of them. They have to clear the deck immediately, if an aircraft in the air has an emergency. So a force of several carriers may have more aircraft an board of each carrier than a single carrier enroute: the aircraft just taken off may land on the other carrier, the carrier with the departure phase can park a lot if aircraft ready for the next sortie on the runway because there is a departure alternate near by.
