Airbus Helicopters H225 vs Beechcraft King Air 360 Er vs Bell 525 Relentless vs Sikorsky S 92

By category, the Beechcraft King Air 360ER is a pressurized twin‑turboprop fixed‑wing utility/business aircraft, while the Airbus H225, Bell 525 Relentless, and Sikorsky S‑92 are twin‑engine medium helicopters typically used for offshore transport, SAR, and government/VIP missions. On range, the King Air 360ER generally offers the longest legs in this group, designed for extended endurance and long cross‑country flights. Among the helicopters, the S‑92 and H225 are broadly comparable long‑range offshore types, with typical mission ranges that can be similar depending on payload and fuel fit, while the Bell 525 is positioned as a modern long‑range helicopter and can be competitive, especially with newer avionics and efficient cruise profiles. Actual range varies heavily with reserves, cabin fit, and operating conditions. For passenger capacity, the helicopters usually carry more people per trip in high‑density configurations: the H225 and S‑92 are commonly arranged for roughly the high‑teens to around 19 passengers, while the Bell 525 is typically in the mid‑teens to high‑teens. The King Air 360ER generally seats fewer, commonly around 8–11 passengers in typical interior layouts.
