X-Plane 10 Scenery--Chehalis-Centralia Airport (KCLS), Washington (WA), USA. Welcome to KCLS Chehalis-Centralia Airport. This is a small General Aviation field located about 20 miles south of Olympia. If you've enjoyed the rendition of KOLM (KOLM_-_OLYMPIA_REGIONAL_AIRPORT.ZIP) then you will definitely want to add KCLS to help fill out the South Sound area. Thanks to Al. for the compass rose, paulmort for the touring caravan, jpb63 for the tractor-mower, and Jacques Brault for the many hangars, buildings, and objects that he has graciously gifted to the community.
