The the left of that phote, just out of sight you have a parking apron for regional props etc.

You could place a T2 there for heavies and shift the props to the top of the picture on the remote stands

Thats where the new terminal developments are destined for.. The Gogar Burn will be culverted and the recent car parks on the old runway 06 will be erased to make room for stands.

The GAT is to be moved over the east side of 12/30 to allow
for further terminal expansion – car parks?

As I said earlier your grandchildren will be be cutting the ribbons. 😀 😀
