Airbus Helicopters H225 vs Bell 525 Relentless vs Gulfstream G700 vs Piaggio Avanti Evo
The Airbus H225 and Bell 525 Relentless are large helicopters, while the Gulfstream G700 and Piaggio Avanti EVO are fixed‑wing business aircraft. For range, the G700 is in a different class, built for ultra‑long‑range intercontinental missions (around 7,500 nautical miles). The Avanti EVO is a short‑to‑midrange turboprop business aircraft, typically suited to regional trips (roughly 1,500–1,800 nautical miles, depending on payload and reserves). The H225 is a long‑range heavy helicopter designed for offshore transport, SAR, and utility work, with practical mission ranges commonly in the several‑hundred‑nautical‑mile class (about 500+ nm depending on configuration). The Bell 525 is a super‑medium helicopter aimed at executive and offshore roles, with range generally similar in order of magnitude, often quoted around the mid‑600‑nautical‑mile class. For passenger capacity, the G700 typically seats in the low‑to‑mid teens in executive layouts, the Avanti EVO usually seats about 7–9, the Bell 525 commonly carries around 12–16, and the H225 can carry more, often around 19 and up to the mid‑20s in high‑density configurations.
