Airbus Helicopters H225 vs Bell 525 Relentless vs Dassault Falcon 8x vs Sikorsky S 92

The Airbus H225 and Sikorsky S-92 are large twin‑engine helicopters typically used for offshore transport and SAR, while the Bell 525 Relentless is a newer-generation super‑medium twin aimed at similar missions with a stronger emphasis on speed and modern avionics. By contrast, the Dassault Falcon 8X is a long‑range tri‑jet business aircraft for intercontinental travel rather than vertical-lift operations. On range, the Falcon 8X is in a different class, offering roughly 6,000+ nautical miles, enabling nonstop long-haul flights. The helicopters are far shorter-legged: the Bell 525 is generally around the low‑to‑mid 500‑nautical‑mile range, while the H225 and S‑92 are commonly in a similar several‑hundred‑nautical‑mile bracket depending on payload, reserves, and configuration. Passenger capacity also reflects the categories. The Falcon 8X typically seats about 12–16 in executive layouts. The helicopters can be configured for higher-density seating: H225 and S‑92 commonly carry around 19 passengers in offshore setups, while the Bell 525 is often configured around 16–19 depending on mission and interior.
