Airbus EC155B1

The EC155B1’s avionics suite blends modern jet-level capability with helicopter precision. A fully digital glass cockpit features dual Primary Flight and Navigation Displays, a 10.4-inch mission display, and a four-axis digital autopilot that delivers fixed-wing stability and control. Dual Garmin GTN 750H GPS/NAV/COM units, Avidyne TAS-620, Telephonics RDR-1600C weather radar, and an L3Harris flight data recorder round out the system—offering total situational awareness, seamless IFR operation, and mission-ready performance in any environment.

The EC155B1 comes loaded with premium mission-ready equipment that elevates it far beyond standard transport configuration. Highlights include a Goodrich Category 2 electrical hoist (272 kg / 90 m) with fixed parts, rappelling installation, wire-strike protection system, Appareo Vision 1000 lightweight flight data camera, and Kannad Integra GPS-linked ELT.

A NAT digital audio and passenger address system, dual Bose headset compatibility, and mechanically driven air-conditioning ensure clear communication and comfort. The aircraft also features Telephonics RDR-1600C weather radar, Avidyne TAS-620 traffic system, L3Harris CV/FDR, and a complete airborne kit for field operations — making it a turnkey, multi-role platform ready for immediate deployment.

The EC155B1 interior is designed for space, comfort, and adaptability. Its flat-floor cabin accommodates up to 13 passengers in transport configuration or can be reconfigured for VIP, EMS, or utility roles. Large sliding doors on both sides provide effortless boarding, while the light grey interior finish, soundproofing, and advanced climate control create a quiet, comfortable environment in all conditions.

Wide tinted windows flood the cabin with natural light and ensure excellent external visibility. The ergonomic cockpit mirrors modern jet standards, with dual pilot seats featuring 5-point harnesses, digital flight instrumentation, and an intuitive glass cockpit layout for superior situational awareness.

Every element—from cabin trim to lighting—reflects a design built for comfort, precision, and operational versatility, setting the benchmark for passenger transport helicopters in its class.

The exterior of the EC155B1 is finished in a clean, high-gloss white base coat, providing a neutral and professional appearance ideal for corporate, offshore, or governmental operations. The airframe features smooth composite contours and the distinctive FENESTRON® shrouded tail rotor, emphasizing both aerodynamic efficiency and safety.

This finish is OEM-applied and fully customizable — ready for client-specific livery, logos, or color schemes. The retractable landing gear, sleek nose profile, and five-blade composite rotor system complete the aircraft’s modern, refined aesthetic — visually aligning high performance with understated elegance.

General Characteristics – EC155B1

The EC155B1 (Light Commercial Helicopter – LCH) is a 5-ton class, twin-engine, multi-role helicopter built by Korea Aerospace Industries (KAI) in partnership with Airbus Helicopters under EASA certification.

A member of the Dauphin family, it combines proven reliability with next-generation comfort and performance. Its five-blade composite main rotor and FENESTRON® shrouded tail rotor deliver smooth, low-vibration flight and the quietest acoustic signature in its class.

The large, unobstructed cabin seats up to 13 passengers in transport layout, or up to 8 in VIP configuration, with a spacious baggage hold accessible from both sides. A retractable tricycle landing gear enables easy ground handling and airport operations, while the high-set rotor disc and fully enclosed tail rotor maximize ground safety.

With dual Safran Arriel 2C2 engines, 4-axis digital autopilot, and jet-level avionics, the EC155B1 delivers long-range comfort, precision handling, and superior mission versatility — equally at home in offshore, HEMS, SAR, corporate, or government roles.

The EC155B1 is powered by two Safran (Turbomeca) Arriel 2C2 engines, each delivering 935 shp (697 kW) with dual-channel Full Authority Digital Engine Control (FADEC).

Engine 1 mirrors this setup — a FADEC-controlled Arriel 2C2 featuring:
• Automatic start sequence and rotor speed governing
• OEI (One Engine Inoperative) training mode
• Anti-icing fuel system effective down to −20°C
• Integrated chip detectors and dual fire detection/extinguishing systems
• Single-side maintenance access for simplified servicing

The result is exceptional reliability, power efficiency, and reduced pilot workload, ensuring smooth, high-performance operation across all mission profiles.

Engine 1 (Arriel 2C2) — Total Time: ~10–20 hours (test runs)

Engine 2 on the EC155B1 is identical to Engine 1 — a Safran (Turbomeca) Arriel 2C2 turbine equipped with dual-channel FADEC for fully automated control, optimized performance, and safety redundancy.

It provides 935 shp (697 kW) and features:
• Automatic synchronization with Engine 1 via the FADEC system
• Independent lubrication and cooling circuits
• Integrated chip detection and fire suppression system
• Anti-icing capability to −20°C
• Phase-angle torquemeter sensors for precise load balancing

Together, both engines deliver smooth, coordinated power, ensuring exceptional single-engine performance, rapid response, and uninterrupted operational reliability even in demanding multi-role environments.
