Airbus Helicopters H175 vs Airbus Helicopters H225 vs Leonardo Aw139 vs Sikorsky S 76d vs Sikorsky S 92

The Airbus H175 and Leonardo AW139 sit in the “medium” twin category, typically used for offshore transport and corporate/VIP missions. In general terms, the H175 offers a strong blend of range and cabin volume, while the AW139 is known for versatile configurations and competitive reach; both commonly seat around 12–16 passengers depending on layout and mission equipment. The Sikorsky S-76D is a smaller “medium/light-medium” twin, optimized for efficient short-to-medium sectors; it usually carries fewer passengers, often about 8–12, and tends to have shorter range than the larger medium twins. Stepping up, the Airbus H225 and Sikorsky S-92 are “heavy” twin helicopters aimed at higher-capacity offshore and SAR roles. They typically provide the longest ranges of this group and the largest cabins, with common passenger capacities roughly in the 16–19 range (again configuration-dependent). Overall, AW139/H175 balance medium-range efficiency and cabin space, S-76D prioritizes smaller-cabin efficiency, and H225/S-92 emphasize maximum payload, capacity, and longer-range offshore capability.
