Bell 525 Relentless vs Dassault Falcon 8x vs Piaggio Avanti Evo vs Robinson R66
The Bell 525 Relentless and Robinson R66 are helicopters, while the Dassault Falcon 8X and Piaggio Avanti EVO are fixed‑wing aircraft; this drives the biggest differences in range, speed, and cabin space. The Falcon 8X is a long‑range large‑cabin business jet, typically carrying about 12–16 passengers (with higher-density configurations possible) and offering roughly 6,000+ nautical miles of range, making it best for intercontinental missions. The Piaggio Avanti EVO is a high‑speed twin‑turboprop aimed at regional flying, usually seating about 6–9 passengers with a range around 1,500–1,800 nautical miles. The Bell 525 is a super‑medium helicopter focused on offshore, corporate, and utility roles, commonly configured for around 12–16 passengers with a range roughly in the 500–600 nautical mile class depending on reserves and fit. The Robinson R66 is a light single‑engine helicopter, typically carrying 4 passengers plus a pilot, with an approximate range around 300–350 nautical miles, favoring short trips, training, and local utility work.
