I have a suggestion...
I know that you have put a lot of work in that project and it is really great but i think the mod needs still one more type of civil plane.
Theres a big plane (YAK 42), two regio-jets, a presidental aircraft but no kind of civil plane, which can land safely and easely on a small&short ArmA grassstrip-airfield.
I think a plane like the ATR 42/ 72 , Bombardier DHC-7 /Dash-8, Dornier Do228/328 or Fokker 50/60 would be great.
They are not too fast and they have the feature that they can land and take-off on short airfields.
What do you think?
