Airbus Helicopters H225 vs Beechcraft King Air 360 Er vs Enstrom 480b vs Robinson R66

The Airbus H225 is a heavy twin‑engine helicopter aimed at offshore, SAR, and utility work. It typically offers the longest helicopter range in this group (roughly 450–600+ nm, configuration dependent) and the highest passenger capacity, commonly around 16–19 passengers in transport layouts. The Beechcraft King Air 360ER is a twin‑turboprop fixed‑wing aircraft optimized for long‑range business and special‑mission flying; it generally delivers the greatest range overall (often about 1,500–1,800+ nm with reserves) but carries fewer people than the H225, typically seating about 9–11 passengers. The Enstrom 480B is a light single‑engine turbine helicopter suited to utility and training roles; its range is usually in the ~250–350 nm class and it commonly seats 4–5 occupants. The Robinson R66 is also a light single‑engine turbine helicopter focused on cost‑effective transport and utility; it typically has similar or slightly greater range than the 480B (~300–350 nm) and usually carries 4–5 occupants. Overall, the King Air leads on range, the H225 leads on payload and seats, and the Enstrom and R66 are lighter, shorter‑range options.
