Airbus Helicopters H225 vs Enstrom 480b vs Piaggio Avanti Evo vs Robinson R66

The Airbus H225 is a large, twin‑engine helicopter in the heavy/transport category, built for offshore, SAR, and utility missions. It offers the greatest passenger capacity of the group (typically around 16–19 depending on layout) and generally a mid-to-long helicopter range (often on the order of a few hundred nautical miles, commonly around 450–500 nm with appropriate tanks and reserves). The Enstrom 480B is a light single‑engine helicopter focused on utility and training; it carries about 4–5 occupants and has a comparatively short-to-moderate range (roughly 250–350 nm). The Robinson R66 is also a light single‑engine helicopter but typically seats 4–5 and often matches or slightly exceeds the Enstrom’s practical range (commonly around 300–350 nm, configuration dependent). The Piaggio Avanti EVO is the outlier: a twin‑turboprop fixed‑wing business aircraft, not a helicopter, with a typical capacity of about 7–9 passengers and by far the longest range here, roughly around 1,500–1,800 nm.
