The PC-6 is famous in the aviation world for its Short Take-off and Landing (STOL) performance on almost any type of terrain - it can take-off within a distance of Template:Convert and land within a distance of Template:Convert while carrying a payload of 1,500 kg (3,300 lb) (The length of a soccer field is enough, Pilatus test pilots were able to land on not much more than Template:Convert of space). Thanks to its STOL performance, the PC-6 holds the world record for highest landing by a fixed wing aircraft, at Template:Convert, on the Dhaulagiri glacier in Nepal.
