Airbus Helicopters H225 vs Beechcraft King Air 360 Er vs Bell 525 Relentless vs Dassault Falcon 8x

The Airbus H225 is a heavy twin‑engine helicopter suited to offshore, SAR, and utility transport; it typically carries around 16–19 passengers and has a practical range on the order of about 400–600 nautical miles depending on fit and reserves. The Bell 525 Relentless is a modern “super‑medium” helicopter aimed at offshore and corporate shuttle missions; it commonly seats roughly 12–16 passengers and offers a similar medium‑range profile, generally around 500–600 nautical miles. The Beechcraft King Air 360ER is a twin‑turboprop fixed‑wing aircraft optimized for efficient regional and special‑mission flying; it usually carries about 6–9 passengers in executive layouts (more in utility configurations) and delivers substantially longer legs, roughly around 1,500–1,800 nautical miles depending on payload and conditions. The Dassault Falcon 8X is a long‑range tri‑jet business aircraft for intercontinental travel; it typically accommodates about 12–16 passengers and has by far the greatest range, about 6,400–6,450 nautical miles, enabling nonstop missions such as transoceanic and deep‑continental city pairs.
