I know development of SP is basically over, but if lights and markings were added to Wright Airport, here's what it could look like:
The rotation of signs tells you what direction they're facing (upside down means they're facing north, right way up is facing south). The yellow and black line is the dividing line between the taxiway and runway. The dotted lines are lights. Hope you like it!
Sorry if quality is a bit bad. I might repost this with a better image.
@PlaneFlightX Add that with some spawnable ai 'aircraft' taxiway signs, runway guard lights, and stop bar lights, and you've basically got this.
