Airbus Helicopters H225 vs Bell 525 Relentless vs Enstrom 480b vs Pilatus Pc 24

The Airbus H225 and Bell 525 Relentless are large, twin‑engine helicopters aimed at offshore, SAR, and utility transport. The H225 is typically configured for roughly 19 passengers and offers long helicopter ranges on the order of about 450–500 nautical miles depending on payload and reserves. The Bell 525 is in a similar category with a comparable cabin class, generally up to about 16–20 passengers, and a similar long‑range profile, often cited around the 500‑nautical‑mile class. The Enstrom 480B is a much smaller light single‑engine helicopter intended for training, patrol, and light utility work. It carries about 4–5 people total and has a much shorter range, roughly in the 250–300 nautical mile class. The Pilatus PC‑24 is a twin‑engine light business jet rather than a helicopter, optimized for fast point‑to‑point travel. It typically carries about 6–10 passengers and has a far longer range, roughly 2,000 nautical miles, dramatically exceeding the helicopters while requiring runway operations.
