Airbus Helicopters H175 vs Airbus Helicopters H215 vs Bell 525 Relentless vs Cessna Skycourier vs Leonardo Aw189 vs Sikorsky S 92

The Airbus H175, Airbus H215, Leonardo AW189, Bell 525 Relentless, and Sikorsky S-92 are all medium-to-heavy twin‑engine helicopters aimed at offshore transport, SAR, and utility missions, while the Cessna SkyCourier is a twin‑turboprop fixed‑wing utility aircraft optimized for short, unimproved runways and high-cycle cargo/passenger service. In passenger capacity, these helicopters typically seat roughly 16 to 19 passengers in offshore-style layouts, with the larger S‑92 generally at the upper end (often up to about 19), and the H215 and AW189 commonly around the mid-to-high teens; the H175 and Bell 525 are similarly in the high‑teens depending on cabin fit. The SkyCourier in passenger configuration is typically around 19 seats, comparable to the bigger helicopters but in an airplane cabin arrangement. For range, the helicopter group generally falls in the several-hundred–nautical‑mile class, with the AW189, H175, Bell 525, and S‑92 commonly offering longer legs than the older-generation H215 depending on tanks and payload. The SkyCourier generally offers a longer cruise range than most helicopters, though mission profiles differ substantially.
