De Havilland DHC-6
De Havilland Twin Otter 300 (DHC-6) - Dash 6 - Capacity: 18-seater: 1 in service
The De Havilland Twin Otter (DHC-6) is a highly maneuverable, versatile aircraft which can be flown slowly (80-160 knots/150-300 km/hr) and in tight circles. The Twin Otter is a high-winged, unpressurized, twin-engine turbo-prop aircraft equipped with colour weather radar, radar altimeter, dual GPS/Loran-C navigation systems with scientific data drops, and camera ports in the nose and belly areas. A standard flight crew consists of two pilots.
Development of the Twin Otter dates back to January 1964 when De Havilland Canada started design work on a new STOL ((short take off and landing) twin turbo-prop commuter airliner (seating between 13 and 18) and utility transport. The new aircraft was designated the DHC-6 and prototype construction began in November that year, resulting in the type's first flight on May 20 1965. After receiving certification in mid 1966, the first Twin Otter entered service with long time De Havilland Canada supporter the Ontario Department of Lands in Canada.
The first production aircraft were Series 100s. Design features included double slotted trailing edge flaps and ailerons that can act in unison to boost STOL performance. Compared with the later Series 200s and 300s, the 100s are distinguishable by their shorter, blunter noses.
The main addition to the Series 200, which was introduced in April 1968, was the extended nose, which, together with a reconfigured storage compartment in the rear cabin, greatly increased baggage stowage area.
The Series 300 was introduced from the 231st production aircraft in 1969. It too featured the lengthened nose, but also introduced more powerful engines, thus allowing a 450kg (1000lb) increase in takeoff weight and a 20 seat interior. Production ceased in late 1988. In addition, six 300S enhanced STOL performance DHC-6-300s were built in the mid 1970s.
