Airbus Helicopters H145 vs Airbus Helicopters H155 vs Sikorsky S 76d

The Airbus Helicopters H145 is a light twin-engine helicopter commonly used for EMS, law enforcement, and utility work. It typically carries about 8 to 9 passengers (plus crew) in a high-flexibility cabin. Its range is generally in the mid-hundreds of nautical miles, often around 300 nm depending on configuration and reserves, making it well suited to short-to-medium missions with frequent landings. The Airbus Helicopters H155 sits in the larger medium-twin class and is often positioned for offshore transport and corporate/VIP missions. It usually accommodates roughly 12 passengers, with a longer typical range than the H145—often around 450–500 nm—supporting longer overwater legs and higher payload comfort. The Sikorsky S-76D is also a medium twin, widely used for offshore and executive transport. It commonly seats about 12 passengers as well, with range typically comparable to the H155—often in the 400–450+ nm class—while emphasizing speed, smooth ride qualities, and strong IFR/offshore capability. Actual figures vary with interiors, fuel, payload, and regulatory reserves.
