Airbus Helicopters H225 vs Leonardo Aw189 vs Piaggio Avanti Evo vs Robinson R66

The Airbus H225 is a heavy, twin‑engine helicopter built for offshore and SAR-class missions, offering the greatest cabin volume and the highest passenger capacity of the group (typically around 19 seats in transport layouts) and a long operational range for a rotorcraft, often on the order of 400+ nautical miles depending on fit and reserves. The Leonardo AW189 is a super‑medium, twin‑engine helicopter positioned below the H225; it generally carries fewer passengers (commonly 16–18) with strong offshore range, typically in the mid‑300 to 400+ nautical mile class, and emphasizes efficiency versus heavy lift. The Piaggio Avanti EVO is not a helicopter but a twin‑turboprop fixed‑wing aircraft; it usually seats about 7–9 passengers and, with higher cruise speed and aerodynamic efficiency, typically delivers the longest range here, often roughly 1,000+ nautical miles. The Robinson R66 is a light, single‑engine helicopter aimed at personal/utility roles; it carries about 4 passengers plus a pilot (5 seats total) and has the shortest range of the group, commonly around 300 nautical miles.
