Airbus Helicopters H225 vs Beechcraft King Air 360 Er vs Bell 525 Relentless vs Bombardier Global 7500

The Airbus H225 and Bell 525 Relentless are long-range twin‑engine helicopters, while the Beechcraft King Air 360ER is a turboprop airplane and the Bombardier Global 7500 is an ultra‑long‑range business jet. In range terms, the Global 7500 is in a different class, capable of roughly 7,700 nautical miles, enabling true intercontinental missions. The King Air 360ER is optimized for endurance among turboprops, typically around 1,500–1,800 nautical miles depending on payload and reserves. The H225 generally offers about 450–700 nautical miles, varying significantly with passenger load, fuel configuration, and mission profile. The Bell 525 is in a similar bracket, commonly cited around 500–600 nautical miles. Passenger capacity also separates them: the Global 7500 is usually configured for about 8–19 passengers in executive layouts; the King Air 360ER typically carries about 6–11. The H225 can carry roughly 19 passengers in high-density transport (often fewer in offshore/VIP), while the Bell 525 is typically around 16–20 depending on seating and mission fit.
