Portland International Airport – KPDX – Taxiway and Runway Glitches Remover v1.0
This fix eliminates glitches on taxiways and runways on the grounds of Portland International Airport. Before that, a safe landing was often not possible. This is remedied by leveling/flatten the terrain. I have not observed any effects on the surrounding scenery or flightsimulator at all, but the application of this fix is at your own risk.
