Dynamic Aircraft Slot

Is there a way to change the aircraft designated to a slot in Multiplayer while the mission is running?

What I am wondering is if there is a way to give an Airfield a # of aircraft and allow players to select a slot and then the aircraft to be spawned in that slot. And once the slot is spawned t removes 1 air-frame from the airfields pool.

Click on the airbase on the map in ME then Full Info button. then uncheck unlimited aircrafts and pick your number. Everytime someone spawns, one airframe will be deducted from storage. If the aircraft lands back at the airport, the storage increases with one airframe. That goes for anyting landing at that airbase.

So I only need 1 slot at that airfield for all players joining?

I am looking for a way for people to be given a single slot at an airfield and then have them select the aircraft they want to spawn in and have them teleport into it to fly.

Not a thing. One slot per airframe/client.

Slots = max number of simultaneous clients in any given airframe type

Airfield resources = total number of airframes of any given type available

If you have 4 F-15 slots and only 3 F-15s available at the field, the 4th pilot will be dumped back to spectators after trying to select an F-15.
