All my JustSim airport runways are white on the map. Orbx and others are gray. I tried changing maps and reloading scenery but no change. Any idea why this happens? Thanks for your help.

MSFS? XP? FSX?

Runways are white if the developer did not assign a surface type.

Or you use Navigraph data only which also does not provide runway surface types. But this would show all runways white.

Its p3d v5. I guess Justsim did not assign a suface type. Thanks.

The runways are probably transparent and the background is done with a photo texture.
