Bell 525 Relentless vs Dassault Falcon 8x vs Embraer Legacy 650 E

The Bell 525 Relentless is a super-midsize-class helicopter, while the Dassault Falcon 8X and Embraer Legacy 650E are large-cabin business jets. In range terms, the Bell 525 is designed for roughly about 1,000–1,200 nautical miles depending on load and mission profile, making it suitable for regional point-to-point flying with the added advantage of vertical takeoff/landing. The Legacy 650E typically offers intercontinental-capable range around 3,900–4,000 nautical miles, supporting longer nonstop trips but generally not true ultra-long-haul city pairs. The Falcon 8X is an ultra-long-range jet at about 6,400–6,450 nautical miles, enabling many nonstop transoceanic routes and giving the widest nonstop reach of the three. Passenger capacity also differs by mission: the Bell 525 commonly seats around 16–20 in a high-density layout but is often configured for fewer in offshore/VIP roles; the Legacy 650E typically seats about 13–14; and the Falcon 8X usually seats around 12–16 depending on cabin configuration.
