Thank you for your quick response.
So I use under Arma 3 Vehicle Loadouts/scripting the available scripting commands to equip in-game on-the-fly helicopters/planes with other loudouts?
I tried the demo example, and inserted the resulting code into the respawn module in the expression field, so I respawned the aircraft with the equipment.
Sorry for choosing the wrong place in the forum.
