Bell 525 Relentless vs Dassault Falcon 8x vs Piaggio Avanti Evo vs Piper M600 Sls
The Bell 525 Relentless is a fly-by-wire super‑medium helicopter, best suited to vertical-access missions rather than long runway-to-runway travel. It typically carries around 16 passengers in a high-density configuration (often fewer in executive layouts) and offers roughly 560 nautical miles of range, emphasizing point-to-point flexibility over transcontinental legs. The Dassault Falcon 8X is an ultra‑long‑range large-cabin business jet designed for intercontinental travel. It generally seats 12–16 passengers (depending on layout) and delivers about 6,450 nautical miles of range, enabling nonstop city pairs that smaller aircraft cannot cover. The Piaggio Avanti EVO is a twin‑turboprop business aircraft known for speed and cabin comfort relative to many turboprops. It typically carries 6–9 passengers and has an approximate range around 1,700–1,980 nautical miles, making it strong for regional and mid-range missions. The Piper M600 SLS is a single‑engine turboprop personal/business aircraft. It usually seats 5–6 passengers and offers about 1,400–1,650 nautical miles of range, favoring owner-operator efficiency over maximum capacity and distance.
