D702 Fort George has been unofficially extended
I don't think that's right. The situation at Fort George is that the air danger area is SMALLER than the surface danger area. The latter extends much further out to the north, towards the Black Isle east of Rosemarkie, than D702. Small arms ranges typically have a surface danger area but no air danger area but they are listed in the AIP and you'll find the Fort George one in there at ENR 5.3-2.
