Airbus Helicopters H225 vs Enstrom 480b vs Leonardo Aw189 vs Sikorsky S 92

All four are twin‑engine medium helicopters, but they sit in slightly different classes. The Enstrom 480B is a light, single‑engine utility helicopter, typically used for training, patrol, and short‑range work; it carries about 4–5 passengers (plus pilot) and has a substantially shorter range than the others. The Airbus H225, Leonardo AW189, and Sikorsky S‑92 are medium/heavy twin‑engine helicopters aimed at offshore transport, SAR, and VIP/utility roles, with far greater payload and endurance. On range, the AW189 generally sits around the mid‑to‑upper end of the medium class (roughly 450–500+ nm depending on fit), the S‑92 is commonly comparable or slightly higher in many offshore configurations (often around 500+ nm), and the H225 is also in this same long‑range offshore bracket, frequently quoted in a similar 450–600 nm neighborhood depending on tanks and mission equipment. On passenger capacity, the AW189 is typically configured around 16–19 seats, the H225 around 19, and the S‑92 often around 19 (with layouts varying by operator and mission), while the 480B remains far smaller.
