Recommended value of suppresion range for slow flying

[Guest steku]

I'm flying GA planes (low and slow) - airspeed about 100kt in Washington state. My typical flight takes about one hour (about 100NM). Could you recommend me value of Suppresion Range for this airspeed and density of reporting stations in Washington?I think that default value for this parameter is more suited for airliners flying hundreds of miles.

Hi,The ideal suppression range is actually more related to reporting station density rather than speed of flight. If the range is too low for the area, FS9 interpolation can cause visible cloud shifts when the wx is updated. Washington has a decent amount of stations, so you should be able to go lower, perhaps down to about 50nm (also depends on your cloud draw distance). You can experiment and find a setting that works best for you. If you get cloud shifts and don't like them, you can up the range appropriately.Hope that helps!
