While paved areas at airports are generally flat, there are times when runways, taxiways and parking areas are sloped. While sloped runways and taxiways in some cases require extra attention, sloped parking areas can cause major problems.
I recently visited a beautiful airport in the southern part of the Sierra Nevada Mountains called Kern Valley Airport (L09) near Kernville, California. There is a terrific cafe and a beautiful campground at the airport, so, while the airport itself is small, the parking areas can get quite busy. The parking area near the cafe fits several rows of airplanes and it slopes severely toward the base of the valley.
