I think that GPS can be helpful for airport ground navigation and avoiding
runway incursions. For some reason, I never see this mentioned in any of
the material on runway incursion. It's not perfect, but if you have one in
the cockpit it might help you maintain situational awareness on the ground.

Anyway, here is something that I put together very quickly last night.
