Airbus Helicopters H225 vs Enstrom 480b vs Robinson R66 vs Sikorsky S 92

The Airbus H225 and Sikorsky S-92 are heavy, twin‑engine helicopters typically used for offshore transport, search and rescue, and other high‑payload missions. Both sit in the top tier here for passenger capacity, commonly configured around the high‑teens (often up to roughly 19), and they also offer the longest practical ranges in this comparison, generally in the several‑hundred‑nautical‑mile class depending on fuel and mission fit. The H225 is often selected when very high lift and long overwater legs are priorities, while the S‑92 is similarly positioned with strong offshore and utility credentials. The Robinson R66 is a light, single‑engine turbine helicopter aimed at cost‑efficient private, utility, and training roles. It typically carries about 4–5 people and has a moderate range suitable for regional missions rather than long offshore legs. The Enstrom 480B is also a light, single‑engine turbine helicopter, generally comparable in role to the R66, with a typical capacity around 4–5 seats and a similar mid‑range endurance, emphasizing stability and utility over maximum payload or long range.
