Airbus Helicopters H225 vs Robinson R66 vs Sikorsky S 92

The Airbus H225 and Sikorsky S-92 are heavy, twin‑engine offshore/utility helicopters, while the Robinson R66 is a light, single‑engine turbine helicopter aimed at private, training, and light commercial missions. In range, the H225 and S-92 generally offer substantially longer legs than the R66 and are commonly configured for extended offshore sectors with typical ranges on the order of several hundred nautical miles, whereas the R66 is more suited to shorter point‑to‑point trips, typically a few hundred nautical miles or less depending on reserves and configuration. Passenger capacity differs sharply: the R66 normally carries a pilot plus four passengers (five seats total), reflecting its light category and smaller cabin. By contrast, the H225 and S-92 are designed to move larger teams; both are commonly outfitted for around 16–19 passengers in transport roles, with high useful load and cabin volume for offshore crews or SAR/EMS equipment. Overall, the R66 prioritizes simplicity and lower operating cost, while the H225 and S-92 prioritize capacity, redundancy, and all‑weather, long‑range utility.
