Airbus Helicopters H175 vs Airbus Helicopters H225 vs Leonardo Aw139 vs Leonardo Aw189 vs Sikorsky S 76d vs Sikorsky S 92

The Airbus H175 and Leonardo AW189 sit in the super‑medium class, typically carrying about 16–19 passengers in offshore-style layouts and offering long legs around the mid‑400 to roughly 500+ nautical‑mile class depending on configuration. The Leonardo AW139 and Sikorsky S‑76D are generally medium helicopters with smaller cabins; they commonly seat about 12–15 passengers and tend to have shorter practical ranges, often roughly in the ~350–450 nautical‑mile band. The Airbus H225 and Sikorsky S‑92 are heavy helicopters optimized for high payload and offshore missions; they usually accommodate around 19 passengers in standard offshore seating, with ranges broadly comparable to or slightly above super‑medium types, commonly around the ~450–550 nautical‑mile class depending on fuel, reserves, and mission equipment. In simple terms, AW139 and S‑76D trade cabin volume for efficiency and agility, H175 and AW189 balance capacity and range, and H225 and S‑92 prioritize maximum cabin/payload and rugged offshore capability while maintaining long range.
