Bell 525 Relentless vs Bombardier Global 7500 vs Dassault Falcon 8x vs Robinson R66

The Bell 525 Relentless and Robinson R66 are helicopters, while the Bombardier Global 7500 and Dassault Falcon 8X are long-range business jets, so they serve very different mission profiles. In category, the Bell 525 is a modern super-midsize twin‑engine helicopter aimed at corporate/offshore roles, whereas the R66 is a light single‑engine turbine helicopter typically used for shorter, lower-cost missions. The Global 7500 is an ultra‑long‑range, large-cabin jet, and the Falcon 8X is a long‑range, large‑cabin trijet optimized for flexibility and access to shorter runways. In range, the jets dominate: the Global 7500 reaches roughly 7,700 nautical miles, and the Falcon 8X about 6,450 nautical miles. Helicopter ranges are far shorter: the Bell 525 is roughly in the 500–600 nautical mile class depending on configuration, and the R66 is roughly around 300 nautical miles. Passenger capacity also separates them: Global 7500 typically carries about 14–19 passengers, Falcon 8X about 12–16, Bell 525 about 16–20 (often fewer in executive layouts), and the R66 about 4–5 including the pilot.
