Airbus Helicopters H225 vs Bell 525 Relentless vs Enstrom 480b vs Sikorsky S 92

All four are twin‑engine helicopters, but they sit in different weight and mission categories. The Airbus H225 and Sikorsky S‑92 are large, heavy‑lift transports commonly used for offshore energy, search and rescue, and government/VIP roles; they typically offer the longest practical reach among this group and the highest passenger capacity, generally configured around the high‑teens to low‑twenties depending on interior and regulatory seating layouts. The Bell 525 Relentless is a newer “super‑medium” twin aimed at offshore and corporate missions; it generally falls between the big heavy twins and smaller utility types, with long range comparable to offshore needs and passenger seating typically in the mid‑teens, again depending on configuration. The Enstrom 480B is a much smaller light helicopter (commonly operated as a single‑engine utility/training platform); it has substantially shorter range than the offshore‑oriented twins and carries far fewer passengers, typically a pilot plus several occupants in a 4–5 seat cabin. Overall, S‑92 and H225 prioritize maximum payload and cabin volume, the 525 balances speed/range with a smaller footprint, and the 480B targets economy and simplicity.
