The general size of everything is small. For example… the a320 wings are sticking out on the street. In real life the a320 wings are very far from the street in the same airport. There’s a way to make it bigger and more realistic or is just Asobo saving memory and efficiency?
I doubt it’s scale related, could be the parking position and many other things. When modelling objects in 3dsmax there’s tools and options to make it to real life scale.
