Typically I use drongos air operations for fixed wing CAS since alive's combat support RTBs then either just takes off again or parks right in the middle on the taxiway. Drongo's mod will RTB then store vehicles in the VAM (virtual aircraft manager). After that you can choose what loadout you want for your aircraft be it CAS, AT, etc. Recently you can assign certain aircraft to the VAM prior to mission start while also giving it a number of assets.
