I have taken a lot of my design hints for the gate detailing from Beijing Capital as hopefully you can see in these shots. Airport markings are so variable that there isn't really a global standard in terms of detailing:
Only two gates have got the treatment so far - the two large gates on the left pier which fit a 747/77W and A380 (or 2 757s) respectively. Above and below you can see the two gates with the red outlines and the white hashing. I haven't done the pier end because I am not sure quite what I'm doing with the airbridges for the A380 gate yet. This isn't the end for this detailing as when the airbridge areas become clearer there will be more hashing for around the jetway; plus of course there is the weathering and oil staining to be done.
