Pilatus PC-6 Porter / Turbo Porter

Pilatus PC-6 V-631 of the Swiss Air Force
The Pilatus PC-6 success is due to providing operators with the flexibility of choice or conversion between roles. These include passenger and/or cargo transport, supply and Para dropping, photographic and aerial survey, forward support, agricultural work, search and rescue, ambulance and a variety of other missions. In addition the Pilatus PC-6 is certified to operate with amphibious or normal floats and also with skis.

The Pilatus PC-6 Porter started with a piston engine. The first PC-6/A Turbo-Porter with French Turbom?ca Astazou II turboprop power, giving vastly improved performance.

The real breakthrough for the aircraft came in 1964, when the PT6A-6A engine was fitted. The current B2-H4-model was introduced in mid 1985, featuring an enlarged dorsal fin, up-rated shock absorbers, new tail-wheel and airframe reinforcement.
