The Twin Otter is a high-wing, twin-engine, turbo-prop aircraft. They are used all over the world and are known for their rugged construction, reliability and short take-off and landing performance. 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. 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 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. 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.
