The runway and taxiway lights are aimed up and do not illuminate the pavement at all (not even a tiny area around each light). That's why you need landing (and often taxi) lights. Even with a landing/taxi light, taxiing on a cloudy or moonless night is enormously difficult -- you can hardly see the yellow line or the turnoffs, and most of the time you're just rolling through a sea of blackness. If anything, the ground in FlightGear is too bright at night. It's appropriate for a well-lit urban area or a full moon on a clear night, but the runway is far too bright for a cloudy night. > For example, do we properly model the impact on night vision > from hypoxia? That's a surprisingly sneaky thing in real life. At night, descending from (say) 6,000 ft enroute altitude to the airport, I have a couple of times had a *lot* of trouble finding the airport at night. I don't feel like I'm having trouble seeing; it's just that the lights don't stand out. That's never a problem if I'm lined up with the runway on an approach, because those lights are so bright and directional, but even then judging the flare is a big challenge.
