Airbus Helicopters H225 vs Bell 525 Relentless vs Md Helicopters (mcdonnell Douglas) 902 Explorer vs Piaggio Avanti Evo

The Airbus H225 and Bell 525 Relentless are large, long-range transport helicopters aimed at offshore energy, SAR, and executive shuttle missions. The H225 is the higher-capacity option, typically carrying around 19 passengers in a standard transport layout, with long-range capability on the order of roughly 450–500+ nautical miles depending on configuration. The Bell 525 is also a large-category helicopter, generally seating about 16–20 passengers, with a similar long-range envelope often cited around the 500+ nautical mile class, again varying with payload and reserves. The MD Helicopters (McDonnell Douglas) 902 Explorer sits a class below as a light twin designed for utility, EMS, and law enforcement. It commonly seats about 8–10 occupants including crew, with a shorter range typically in the ~250–350 nautical mile range. The Piaggio Avanti EVO is not a helicopter but a pressurized twin-turboprop airplane, positioned as a fast executive aircraft. It usually carries 7–9 passengers, but offers substantially longer range than the rotorcraft—often around ~1,400–1,800 nautical miles—making it better suited to longer point-to-point travel.
