Airbus Helicopters H225 vs Bell 525 Relentless vs Enstrom 480b vs Md Helicopters (mcdonnell Douglas) 902 Explorer

All four are twin‑engine helicopters but sit in different weight and mission categories. The Airbus H225 is a heavy, long‑range offshore/utility transport, typically offering the greatest endurance and payload, and it generally carries the most people, commonly configured around 19 passengers (and higher‑density seating in some layouts). The Bell 525 Relentless is a modern “super‑medium” aimed at offshore and corporate roles; its range is typically in the same long‑range class but below the H225, and its passenger capacity is usually in the mid‑teens depending on configuration. The MD Helicopters 902 Explorer is a light twin optimized for EMS, law enforcement, and corporate shuttle; it has a shorter range than the H225/525 and typically seats about 8–10 including crew, depending on interior and mission kit. The Enstrom 480B is the smallest category here (a light turbine, commonly treated as single‑engine in type discussions), suited to utility, training, and patrol; it has the shortest range of the group and usually seats up to 5.
