BK117 C-1

The BK117 C-1, a coproduction between EUROCOPTER and KAWASAKI, is a multi-mission medium-weight class, twin-engine civil helicopter.

Due to the modular design of the helicopter and the optional quick-change equipment, a complete mission change is possible within a very short time. The spacious cabin/cargo compartment has a large usable volume and a one level floor.

It is easily accessed via two hinged crew doors, two sliding passenger doors and two large rear clamshell doors.

Easy loading of stretchers (even with rotors turning), availability of state-of-the-art medical equipment, and low vibration level during flight make the BK117 C-1 one of the leading twin-engined EMS/SAR helicopters in the world.

The BK117 C-1 is fitted with two Turbomeca Arriel 1E2 power plants with automatic speed control, in addition to a modified tail rotor, and possesses outstanding flight characteristics. Its extraordinary performance in flight wins the helicopter immediate popularity and its rigid rotor system (Bölkow) makes for exceptional maneuverability.

While engine and helicopter performance of both are approximately the same in standard day/sea level conditions, the BK117 C-1 is especially well-designed to perform in " hot and high " conditions. The low maintenance and operating costs reflect the high standard of quality and reliability of the aircraft.
