TECHNICAL SPECIFICATIONS & STANDARD EQUIPMENT LIST TECHNICAL SPECIFICATIONS & STANDARD EQUIPMENT LIST Aircraft Overview The Viking 400S Twin Otter (“400S”) is an all-metal, high wing monoplane, powered by two wing-mounted turboprop engines, The aircraft is delivered with two Pratt and Whitney PT6A-27 driving three-bladed, reversible pitch, fully feathering propellers. engines that incorporate platinum coated CT blades. The aircraft carries a pilot, co-pilot, and up to 17 passengers in standard configuration with a 19 or 15 passenger option. The The 400S will be supplied with new generation composite floats aircraft is a floatplane with no fixed landing gear. that reduce the overall aircraft weight (when compared to Series 400 Twin Otters configured for complex utility or special mission The 400S is an adaptation of the Viking DHC-6 Series 400 Twin operations). The weight savings allows the standard 400S to Otter (“Series 400”). It is specifically designed as an economical carry a 17 passenger load 150 nautical miles with typical seaplane for commercial operations on short to medium reserves, at an average passenger and baggage weight of 191 segments. lbs. (86.5 kg.). The Series 400 is an updated version of the Series 300 Twin Otter. The changes made in developing the Series 400 were 1. General Description selected to take advantage of newer technologies that permit more reliable and economical operations. Aircraft dimensions, Aircraft Dimensions construction techniques, and primary structure have not Overall Height 21 ft. 0 in (6.40 m) changed.

(531 m) ISA+10 Maximum Cruise Speeds, TAS 2,000 ft. 153 kt 4,000 ft. 154 kt 8,000 ft. 156.5 kt Enroute Rate of Climb at Sea Level Both engines at max climb power 1,347 ft./min Service Ceiling (Rate of Climb 100 ft/mm) Both engines max climb power 22,000 ft. (6,706 m) One engine max cont. power 4,500 ft. (1,372 m) Payload Range (incl. two pilots totaling 380 lbs.) Payload for 50nm range 3,636lbs. (1,649 kg.) Payload for 100nm range 3,429lbs. (1,555 kg.) Payload for 150nm range 3,245lbs. (1,472 kg.) Payload for 200nm range 3,039lbs. (1,378 kg.) Performance Assumptions Used All takeoff distances are based on both engines operating at takeoff power throughout. The takeoff and landing distances are given at sea level, zero wind and calm water surface. Payload range data is based on the following assumptions: o Cruise at maximum cruise power at 8,000 ft. (2,438 m) for both 150 nm and 225 nm segments, and at 5,000 ft. (1,524 m) for both 50 nm or 100 nm segments, o Climb at maximum power and descent at 500 feet / minute, o Taxi, takeoff and landing fuel allowance of 35 lbs. (16 kg.), o Fuel reserve of 300 lbs. (136 kg.); and o Fuel consumption based on engine manufacturer's specifications. Operational Empty Weight is 8,305 lbs. (3,767 kg.) and assumes a standard aircraft fitted with 17 commuter seats operating with a crew of 2 at 190 lbs. (86.2 kg.) each. All performance data assumes ISA+10 conditions.
