Airbus Helicopters H225 vs Beechcraft King Air 360 Er vs Bell 525 Relentless vs Pilatus Pc 24

The Airbus H225 and Bell 525 Relentless are long‑range offshore/utility helicopters, while the Beechcraft King Air 360ER is a pressurized twin‑turboprop airplane and the Pilatus PC‑24 is a light business jet. In range terms, the PC‑24 generally offers the longest point‑to‑point capability at roughly 2,000 nautical miles class, suited to fast regional and some transcontinental trips. The King Air 360ER is also long‑legged for a turboprop, commonly cited around the 1,800–2,000 nautical mile class depending on payload and reserves. Helicopters trade speed and range for vertical access; the H225 is typically in the ~450–500 nautical mile class, while the Bell 525 is broadly similar, often quoted in the ~500–600 nautical mile class depending on configuration. Passenger capacity differs by mission: the H225 is the largest here, often configured for about 16–19 passengers, the Bell 525 typically around 12–16, the King Air 360ER commonly carries about 8–11, and the PC‑24 usually seats about 6–10 in executive layouts (more in commuter-style configurations).
