I am a fan of elder aircrafts, both civilian and military ones. And GSX does not support this sort of aircrafts in a good way. I for sure understand that a product which works on so many other aircrafts and airports of cource have problem with some and that modern ones have priority. But if it is possible to fix it for this sort of aircrafts in the future so will I be very glad. I will suggest some things which may will fix it a bit.
One thing is the same as I have suggested in other threads, to have a pull back truck to complete the pushback ones. Now will the pushback truck drive in to the aircraft and the wingman will walk throw the aircraft and its wings. Or what happens ones with one aircraft the pushback truck crashed the aircraft when it tried to reached the backwheel, but that would a pull back one have solved.
Another thing which is may not so difficult to solve is the position of the marshall at the gate. When you come close enough you will not see his sign anymore, depending on the Dc-3's construction. Is it possible that to make the marshall stand at the left side of the aircraft. Here I discovered how well done the GSX is, I nearly drove over the marshall and he bowed(can not find a better word), so he did not get the aircraft in his head, lovely done. But is it possible for the program to 'read' when it is an aircraft like the Dc-3 or B-17 which is coming so the marshall stand a couple of meters to the pilots side?
