Bell 525 Relentless vs Dassault Falcon 8x vs Enstrom 480b vs Sikorsky S 92

The Bell 525 Relentless and Sikorsky S-92 are medium/heavy, twin‑engine helicopters aimed at offshore and corporate transport, while the Enstrom 480B is a much smaller single‑engine light helicopter typically used for training, utility, and short hops; the Dassault Falcon 8X is a long‑range trijet business jet built for intercontinental travel. In range, the Falcon 8X is in a different class, capable of roughly 6,000+ nautical miles, enabling nonstop transoceanic missions. The S-92 and Bell 525 are far shorter-legged by comparison, generally around the 500–600 nautical mile neighborhood depending on configuration and reserves, suited to regional missions. The Enstrom 480B is shorter still, commonly a few hundred nautical miles. Passenger capacity follows the same pattern: the Falcon 8X typically carries about 12–16 passengers in executive layouts; the S-92 can seat around 19 in high-density transport (often fewer in VIP); the Bell 525 is commonly configured for about 16–20; and the Enstrom 480B generally carries 4–5 including the pilot.
