Bell 525 Relentless vs Dassault Falcon 8x vs Enstrom 480b vs Piaggio Avanti Evo
The Bell 525 Relentless and the Enstrom 480B are helicopters, while the Dassault Falcon 8X and Piaggio Avanti EVO are fixed‑wing business aircraft. In category and mission, the Bell 525 is a modern super‑medium twin designed for longer offshore, utility, and executive missions; the Enstrom 480B is a light single‑engine piston helicopter optimized for shorter-range transport, training, and patrol-type flying. The Falcon 8X is a long‑range, large‑cabin trijet business jet built for intercontinental travel, whereas the Avanti EVO is a high‑speed turboprop business aircraft aimed at efficient regional to medium-range trips. On range, the Falcon 8X is the clear leader with intercontinental capability. The Avanti EVO offers substantially less range than the 8X but more than typical light helicopters, fitting city-pair business missions. The Bell 525’s range is long for a helicopter and well-suited to extended overwater legs, but it remains below long-range jets. The Enstrom 480B has the shortest range of the group. For passenger capacity, the Falcon 8X typically carries the most passengers in executive layouts, the Avanti EVO generally seats fewer, the Bell 525 carries a moderate passenger load, and the Enstrom 480B carries the fewest.
