About the DeHavilland Canada Twin Otter

Overview

The DHC-6 Twin Otter is a legendary STOL utility aircraft capable of operating from unprepared strips, water, and snow. Originally developed by de Havilland Canada and later revitalized by Viking Air, it is the global standard for remote operations and skydiving.

Key Features for GA Buyers

STOL Performance: Capable of clearing a 50 ft obstacle in just 1,200 ft, allowing access to virtually any clearing or short strip.
Versatility: Can be equipped with standard wheels, tundra tires, skis, or amphibious floats without structural modification.
Rugged Systems: Fixed landing gear and simple mechanical systems ensure high dispatch reliability in extreme environments.

Trade-offs

Cruise Speed: With a typical cruise of 150-170 knots, it is significantly slower than pressurized commuters like the Beech 1900 or Metro.
Unpressurized: Limits comfortable cruising altitudes to below 10,000 ft for passengers, though it has a 25,000 ft ceiling for specialized missions.
