Leonardo Aw189 vs Robinson R66 vs Sikorsky S 92

The Leonardo (Agusta) AW189 and Sikorsky S‑92 sit in the medium twin category, aimed at offshore transport, SAR, and utility missions, while the Robinson R66 is a light single‑engine turbine helicopter typically used for private, training, patrol, and light commercial work. In range, the R66 generally offers the shortest legs because it is smaller and optimized for lighter loads, whereas the AW189 provides substantially longer practical range for regional/offshore sectors, and the S‑92 is commonly configured for comparable or longer offshore-capable legs depending on fuel and payload tradeoffs. Passenger capacity differs sharply: the R66 is usually a 4–5 seat aircraft including the pilot, the AW189 typically carries around 16–19 passengers in standard transport layouts, and the S‑92 is often configured for roughly 19 passengers (with variants and seating options that can shift this slightly). Overall, the R66 prioritizes simplicity and operating cost, the AW189 targets efficient medium-class lift and modern avionics, and the S‑92 emphasizes higher gross weight capability, cabin volume, and established offshore performance.
