AI Take off, go into loop, refuel when it needs to, repeat?

[SpaceWaffle]

So I'm making a little mission for me and my friends where we can do target practice including both ground and air units.
I wanted to make the air units take off from their airfield, fly in circles endlessly untill they have to refuel, land to refuel, take off again and repeat untill destroyed.
Does anyone know how to do this?

Give them an orbit task and then make their landing waypoint ReFuAr to make them refuel and take off again. You could also provide the AI with a tanker to let them refuel in the air. You can find more info in the DCS Manual under waypoints and waypoint actions.

The landing might not be necessary at all though. Even fighter aircraft can orbit for hours if set up correctly. Large transports and AWACS and can orbit for over 4 hours.
