Premier aircraft design twin otter series#
Special Missions & Aircraft UsesĪ Special Missions variant of the Series 400, the Twin Otter Guardian 400, has also been developed for intelligence, surveillance and reconnaissance (ISR) operations. However, like its predecessor, the Twin Otter Series 400 retains the ability to operate economically, safely and reliably from remote and unimproved airfields due to its robust design, equalized maintenance program and dependability of the Pratt & Whitney engines. The Twin Otter Series 400 picks up where the original De Havilland Series 300 Twin Otter left off, introducing upgraded Pratt & Whitney PT6A-34 engines, fully integrated Honeywell Primus Apex digital avionics suite, internal and external LED lighting, and approximately 800 other modifications incorporated to improve upon the original production model. The first production aircraft was delivered in 2010 and by mid 2015, 75 of the new series had been delivered. After an extensive market analysis was conducted, it was determined that an overwhelming demand existed to bring the Twin Otter back into production, thus the Viking Series 400 Twin Otter Production Program was announced in 2007.
In 2005, Viking purchased the Type Certificates for all of the out-of-production De Havilland aircraft (DHC-1 through DHC-7), including the Twin Otter. Viking puts the Twin Otter back in Production A testimony to its rugged construction and incredible STOL performance, the Twin Otter became the best-selling 19 passenger aircraft of all time, still unmatched for its dependability and versatility. The Twin Otter aircraft have been sold around the world to customers operating in the harshest environments, including sub-zero temperatures in Antarctica, the hottest deserts of North Africa, the mountainous regions of the Himalayas, and the open water of the Indian Ocean archipelagos. Designed as a rugged Short Take Off and Landing (“STOL”) commuter, the Twin Otter was capable of carrying passengers and cargo into remote unimproved locations, including ski and water-based operations. In 1965, De Havilland Canada developed the DHC-6 Twin Otter aircraft – a high winged, un-pressurized twin engine turbine powered aircraft with fixed tricycle land gear.
