Airbus Helicopters H225 vs Beechcraft King Air 360 Er vs Leonardo Aw189 vs Robinson R66

The Airbus H225 and Leonardo AW189 are large, twin‑engine helicopters aimed at offshore transport and search‑and‑rescue; both typically carry around 16–19 passengers depending on fit. In range, they are broadly similar, commonly operating roughly in the 400–500 nautical mile class, with actual figures varying significantly by payload, reserves, and mission equipment. The AW189 generally sits slightly below the H225 in size and maximum lift, but both are in the “super‑medium/heavy‑leaning” helicopter category compared with smaller utility types. The Robinson R66 is a light, single‑engine helicopter suited to shorter missions such as training, patrol, and light utility work, usually carrying 4 passengers plus a pilot (five seats total) and offering a much shorter practical range, commonly around 300 nautical miles or less depending on conditions. The Beechcraft King Air 360ER is a twin‑turboprop fixed‑wing aircraft, not a helicopter. It typically carries about 6–9 passengers in executive layouts and, as a fixed‑wing platform, offers far greater range than the rotorcraft listed, commonly on the order of 1,500–2,000+ nautical miles, depending on configuration and reserves.
