The EC155 B1 is the most advanced medium bi-turbine helicopter in its category. Produced by Airbus, the EC 155 is a derivative of the well-known AS365 N3 with higher take-off weight, increased fuselage, a new 5-blade main rotor and updated avionics. The EC 155 cabin is large enough to carry eight passengers ( six well installed), plus one in the cockpit. It reaches a speed of 322 kilometers per hour, with a range of 858 kilometers.
