Bell 525 Relentless vs Dassault Falcon 8x vs Embraer Legacy 650 E vs Piaggio Avanti Evo
By category, the Bell 525 Relentless is a super‑medium, fly‑by‑wire helicopter aimed at point‑to‑point and offshore missions, while the Dassault Falcon 8X is an ultra‑long‑range, large‑cabin business jet optimized for intercontinental travel. The Embraer Legacy 650E is a large‑cabin, long‑range business jet positioned below the 8X in range and cabin class, and the Piaggio Avanti EVO is a high‑speed turboprop business aircraft often used for efficient regional missions. On range, the Falcon 8X leads at roughly 6,400 nautical miles, enabling true global city pairs. The Legacy 650E follows at about 3,900 nautical miles, covering most transcontinental and many transatlantic routes with reserves. The Avanti EVO is typically around 1,700–1,800 nautical miles, suited to shorter business legs. The Bell 525’s range is much shorter than the fixed‑wing aircraft, generally in the several‑hundred‑nautical‑mile class depending on payload and reserves. For passenger capacity, the Falcon 8X and Legacy 650E commonly seat about 12–14 in executive layouts, the Avanti EVO typically around 6–9, and the Bell 525 usually about 12–16 depending on configuration.
