Courchevel Airport (Altiport de Courchevel)
Factors such as difficult approach, an upslope runway and a neighbourhood peppered with ski runs make flight operations at Courchevel Airport (Altiport de Courchevel), situated in a skiing area of the French Alps Mountains.
The airport’s 525m-long short runway with a gradient of 18.5% handles smaller fixed-wing aircraft as well as helicopters. The runway lacks instrument approach procedures, thus touchdown in fog and low clouds is nearly impossible. A go-around procedure is common at the airport and night flights are banned.
Princess Juliana International Airport, St Martin

The air traffic control tower illuminates a strobe light to indicate aircraft movements. Pilots flying from/to the airport must deal with irregular sea tides while taking off and landing as the runway is swamped at high tide.
