Airbus Helicopters H225 vs Piaggio Avanti Evo vs Robinson R66 vs Sikorsky S 92

The Airbus H225 and Sikorsky S‑92 are heavy, twin‑engine helicopters typically used for offshore transport and SAR; they sit in the largest category here, offering the highest passenger capacity (commonly around 16–19 passengers in typical layouts) and long helicopter ranges, generally on the order of roughly 450–550 nautical miles depending on configuration and reserves. Between them, the S‑92 is often configured for high‑density offshore seating, while the H225 is similarly capable with strong hot‑and‑high and payload performance. The Robinson R66 is a light, single‑engine helicopter aimed at cost‑efficient private, training, and utility missions. It carries up to about 4 passengers (plus pilot) and has a much shorter range, roughly 300–350 nautical miles, making it best for regional point‑to‑point trips rather than long overwater sectors. The Piaggio Avanti EVO is not a helicopter but a pressurized twin‑turboprop airplane. It generally carries 6–7 passengers (plus crew) and typically offers the longest range of the group, often around 1,000–1,400 nautical miles, excelling at fast regional travel between airports rather than vertical‑lift missions.
