What is your suggestion?
Once a plane reaches the 4th Large maintanence check, the ability to convert the plane to a cargo aircraft would be possible (only for aircraft that have an available cargo variant)
How would it work in the game?
the planes would operate like they already do as cargo aircraft, and for the UI, a Seperate button would be shown to convert the plane to a cargo aircraft, as this would be an option and not a requirement.
Why is this a good idea?
this is something that happens a lot in real life (the entire existence of some cargo aircraft is due to this practice) and would also add another level of realism to the game
