Airbus Helicopters H225 vs Beechcraft King Air 360 Er vs Bell 525 Relentless vs Leonardo Aw189

The Airbus H225 and Leonardo AW189 are heavy, twin‑engine helicopters suited to offshore transport and utility work. Both typically carry around 16–19 passengers in high‑density seating, with practical ranges roughly in the 450–550 nautical mile class depending on payload and reserves; the H225 is generally positioned as the larger, higher‑gross‑weight option, while the AW189 sits slightly lighter with similar mission profiles. The Bell 525 Relentless is a next‑generation “super‑medium” twin helicopter aimed at offshore and corporate missions. It typically seats about 16–19 passengers and offers a comparable mid‑hundreds‑of‑nautical‑miles range, often competitive with heavy twins depending on configuration, while emphasizing speed, avionics, and modern fly‑by‑wire design. The Beechcraft King Air 360ER is different in category: a twin‑turboprop fixed‑wing aircraft. It generally carries fewer passengers than the offshore helicopters in executive layouts (often 6–9, with higher‑density options possible), but it delivers substantially longer range—about 2,000+ nautical miles—along with higher cruise efficiency for point‑to‑point travel between runways.
