Bell 525 Relentless vs Dassault Falcon 8x vs Piaggio Avanti Evo

The Bell 525 Relentless is a fly-by-wire, super‑medium helicopter suited to point-to-point access where runways aren’t available, with a typical range around 560 nautical miles and seating generally configured for about 12 to 16 passengers depending on layout. The Dassault Falcon 8X is a long‑range, three‑engine business jet designed for intercontinental missions, offering roughly 6,400 nautical miles of range and a typical executive cabin for about 12 to 14 passengers (with higher-density configurations possible). The Piaggio Avanti EVO is a high‑performance twin‑turboprop business aircraft, positioned between light jets and larger turboprops, delivering about 1,700 to 1,800 nautical miles of range and usually seating 6 to 8 passengers in an executive configuration. In short, the 525 emphasizes vertical access and flexibility at shorter ranges, the 8X prioritizes maximum range and cabin comfort for long-haul travel, and the Avanti EVO targets efficient regional missions with jet-like speed for its class and a smaller passenger load.
