After flying almost exclusively around the UK since World Update 3 dropped, I went back stateside to find some real mountains. I have fond memories of using Holger Sandmann’s Cascade River Gorge mesh addon from the FSX days, so went to check out how the area compares in FS2020 after the US DEM update.
The route I took departed Yakima (KYKM) and followed various river valley systems through steep sided gorges and mountain passes, to circle both the summit of Mount Rainier and Mount St Helens before dropping back to Southwest Washington Regional (KKLS). The .PLN file created in LittleNavMap has been uploaded to worldtour.flights for others who might wish to fly the route.
Suggested altitude is 7500 feet for terrain clearance, with high level clouds and a 1600 local time departure making for some beautiful late afternoon lighting on the 1 hour 10 minute flight.
