Airbus Helicopters H225 vs Bell 525 Relentless vs Cessna 208b Grand Caravan Ex vs Leonardo Aw189

The Airbus H225, Bell 525 Relentless, and Leonardo AW189 are all medium-class twin‑engine helicopters aimed at offshore transport, SAR, and utility work, while the Cessna 208B Grand Caravan EX is a single‑engine fixed‑wing turboprop used for short‑haul regional, cargo, and remote operations. In range, the Grand Caravan EX typically offers the longest legs in practical regional service, often around 900–1,000+ nautical miles depending on load and reserves, whereas the AW189 and Bell 525 generally sit in the mid‑to‑upper hundreds of nautical miles, and the H225 is commonly comparable or slightly higher depending on configuration and auxiliary tanks. For passenger capacity, the helicopter trio usually supports roughly 16–19 passengers in typical offshore seating, with maximum high‑density layouts varying by operator and mission kit; the H225 is often considered the “largest” of the three in cabin volume and offshore payload class. The Grand Caravan EX commonly seats about 9–14 passengers depending on interior and certification, trading vertical‑lift flexibility for greater cruise efficiency.
