Snow on runway can be unrealstic, few runways do not get coated with snow.
MSFS does not see to simulate an Snow Clearing, and it is hit-or-miss how much snow accumulate on different textures.
One way to improve this, and to remove the snow on Runways, is to turn off Airport:Color in the Dev menu
Not idea, but at least you can then see the Runways & taxiways, with some sort of SIM Simulated snow clearance.
Who know what trick & work around Orbx might be using when generating Scenery !!,
I CUSTOM scenery “maybe” could have the option to clear the runways & taxiways of snow, with some form of “option switch” ??
I tried at CYUY a default airport and it did indeed make the runways/taxiways a lot more realistic in regards to snow cover. Seems 3rd Party airports such as Orbx LOWI handle this in a different way.
Well it actually IS realistic and cool… at my local airport/aerodrome if there is snow on the grass then there is snow on the runway. Only commercial airports clear snow and probably only the larger ones in many areas. So they would have to make a decision which ones to clear.
A suggestion would be controlled airports with more than 6000ft of runway, for example.
That is obviously the LONG Term, and far more complex solution.
This topic was a TIP for a possible temporary work around.
The simulation of Snow, its accumulation, melting, manual removal, is most likely a very complex thing to simulate, especially if Asobo is going to add, or allow 3rd party devs to add, AI Snow Plows at Airport ( 2028 maybe ? )
They certainly have… but if they’ll ever get bored… after “we need trains” and “real time street traffic”… maybe they can do something about it
