history

{| |}

The Pilatus PC-6 Porter is a civilian utility aircraft built by Pilatus Aircraft of Switzerland.

Design and development

The first prototype made its maiden flight on 4 May 1959 powered by a 254 kW (340-shp) piston engine. The first Turbo Porter, powered by a turboprop, flew in 1961. The Turbo Porter received an engine upgrade in 1963, which increased its power to its present value of 410 kW (550-shp).

In the United States, the Porter was manufactured under license by Fairchild Hiller. In service with the U.S. Air Force, it received the designation AU-23A Peacemaker. In U.S. Army use, it was designated UV-20 Chiricahua.

Operational history

The PC-6 is noted for its Short Take-off and Landing (STOL) performance on almost any type of terrain - it can take-off within a distance of and land within a distance of 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 of space). Thanks to its STOL performance, the PC-6 holds the world record for highest landing by a fixed wing aircraft, at , on the Dhaulagiri glacier in Nepal.
