Airbus Helicopters H215 vs Airbus Helicopters H225 vs Leonardo Aw189 vs Sikorsky S 92

All four are medium/heavy twin‑engine helicopters aimed at offshore transport, SAR, and utility work, but they sit in slightly different weight and capability bands. The Airbus H215 (AS332 L1e) is generally the “lower” end of the heavy‑class group here: it offers long‑range offshore capability with a typical passenger layout around 19 seats, and range that is competitive but usually below the newest‑generation machines when similarly configured. The Airbus H225 (EC225/H225) is the more capable, higher‑performance Airbus option, still commonly configured around 19 passengers, with longer practical offshore reach than the H215 and a stronger emphasis on payload‑range and mission equipment. Leonardo’s AW189 is a modern “super‑medium” rather than a traditional heavy; it typically carries about 16–19 passengers depending on layout, with very strong range for its class and efficient offshore economics. The Sikorsky S‑92 is a heavyweight offshore workhorse, typically around 19 passengers, and is often selected where robust payload, endurance, and all‑weather offshore capability are priorities; its range is broadly comparable to the H225 and generally above older heavy designs, depending on fit and reserves.
