The only other things I would say are pretty minor points really:
1.
Your hold-short nodes are unrealistically close to the runway. This means that when your AI are waiting to take-off while another aircraft is on approach, the seperation between the arriving and departing aircraft will be unrealistically close. It can look a bit disconcerting, especially if you are used to seeing real aircraft ops in action. In less developed parts of the world, sometimes this might be realistic, but generally speaking hold-shorts are placed much further from the runway in the real world than in most default FS airports.
However, there is a limit in FS as to how far away from the runway you can place these hold-short nodes. Press "h" on your keyboard to display the hold-short limiting circles. These circles must must touch/cross the edges of the runway. So if this is something you want to address in your afcad, I suggest that you move your hold-short nodes further away from the runway, but make sure the circles still intersect the
edge of the runway - so don't move them
too far away.
A tip of mine would be to create new nodes
instead of moving the current ones. Then,
delete the current ones and
re-draw the taxiways. This will help prevent odd graphics due to poorly aligned taxiway links, which are sometimes the result of having dragged a node that was part of a straight line section of twy links. But each to their own
2.
You have one or two twy links set to "closed". Unfortunately, this won't stop aircraft from using these links. I have attached my old file to show you how I overcame that problem - and it results in a better look.
Check out the point where the two disused runways cross, north of Rwy 26-08. Your afcad definitely looks better overall, but mine still has the odd good point
3.
Naming of parking positions and orientation of parking spots: I understand that the parking stand numbers and orientation of the parking to the South of runway 26-08 in my afcad are correct, so you may want to check your numbers again. I don't know why I marked mine as "Gate", and I don't suggest that you do this either! Strange....
The radius of your Nimrod parking spots seems rather small. These stands are large enough to park visiting VC10s, so you may want to enable this behaviour in your afcad too. I would suggest a radius of at least 31m or more. Appropriate coding of these spots will keep them free of any unwanted visiting aircraft.
4.
This is probably even
less important than my other two points, but what the hell...
It might be safer if you close the two disused runways in your afcad file. Currently, they are selectable for both landing and take-off. You need to tick the relevant boxes in their properties menus.
HTH,
