Bell 525 Relentless vs Bombardier Global 7500 vs Enstrom 480b vs Piaggio Avanti Evo
The Bell 525 Relentless and Enstrom 480B are helicopters, while the Bombardier Global 7500 and Piaggio Avanti EVO are fixed‑wing business aircraft. For category and mission, the Bell 525 is a large, fly‑by‑wire super‑medium helicopter aimed at offshore and high‑utilization transport; the Enstrom 480B is a light single‑engine utility helicopter typically used for training, patrol, and short‑range passenger work. In range, the Global 7500 dominates as an ultra‑long‑range business jet capable of roughly 7,700 nautical miles, enabling intercontinental nonstop flights. The Piaggio Avanti EVO sits in the middle as a high‑speed twin‑turboprop with about 1,700–1,800 nautical miles of range, suited to regional business travel. Helicopter range is much shorter: the Bell 525 is roughly in the 500–600 nautical mile class depending on configuration, and the Enstrom 480B is closer to about 300 nautical miles. For passenger capacity, the Global 7500 typically carries around 8–19 depending on layout; the Avanti EVO usually seats about 6–9; the Bell 525 commonly seats around 12–16 in transport layouts; and the Enstrom 480B carries about 4–5 including the pilot.
