Hi Nick, Yes all other players aircraft are above the ground while i'm either in the tower or in an aircraft.
I have Orbx Nor-Cal and PNW. this issue only happens in these regions and not in any default scenery. This issue started out of the blue, one day it worked fine next day aircraft elevations are incorrect both in tower and in aircraft. I upgraded to Orbx central and downloaded any updates and the problem still persists. If i understand right there is no elevation fix in these products like in global vector or the like. Please help! Thank you Karlo
