Airbus Helicopters H225 vs Cessna 208b Grand Caravan Ex vs Leonardo Aw189 vs Robinson R66

The Airbus H225 and Leonardo AW189 are large, twin‑engine helicopters aimed at offshore, SAR, and utility missions. The H225 generally offers the greatest lift and cabin volume, typically carrying around 16–19 passengers and delivering long helicopter range on the order of roughly 450–500+ nautical miles depending on fit and reserves. The AW189 sits a step below in size, commonly configured for about 12–16 passengers, with a broadly similar long-range profile, often around 450–500 nautical miles. The Robinson R66 is a light, single‑engine helicopter intended for training, patrol, and light utility work; it typically seats 4–5 occupants and has a much shorter practical range, roughly 300–350 nautical miles. The Cessna 208B Grand Caravan EX is a single‑engine fixed‑wing turboprop used for regional transport and cargo. It typically seats 9–14 passengers (often 9 in commuter layouts) and usually exceeds the smaller helicopter’s range, commonly around 900–1,000+ nautical miles, while trading off vertical lift and hover capability for speed and efficiency.
