Bell 525 Relentless vs Dassault Falcon 8x vs Leonardo Aw189 vs Sikorsky S 92

The Bell 525 Relentless and Sikorsky S-92 are large, long-range helicopters aimed at offshore, SAR, and VIP missions, while the Leonardo AW189 is a slightly smaller “super-medium” helicopter optimized for similar roles with lower typical operating footprint. In contrast, the Dassault Falcon 8X is an ultra-long-range business jet built primarily for intercontinental executive travel rather than vertical-lift utility. On range, the Falcon 8X is in a different class, capable of true long-haul nonstop flights (roughly 6,000+ nautical miles depending on payload and conditions). The helicopters are far shorter-legged by comparison: the Bell 525 and S-92 are generally in the ~500–600 nm class, with the AW189 typically around the ~450–500 nm class, all varying with reserves, passenger load, and mission equipment. On passenger capacity, the Falcon 8X typically carries about 12–16 in executive layouts. The AW189 commonly seats around 16–19, the Bell 525 around 16–20, and the S-92 often about 19, with higher-density configurations possible for all three helicopters.
