Airbus Helicopters H225 vs Bell 525 Relentless vs Dassault Falcon 8x vs Gulfstream G700

The Airbus H225 and Bell 525 Relentless are large helicopters, while the Dassault Falcon 8X and Gulfstream G700 are long‑range business jets. In category terms, the H225 is a heavy, twin‑engine rotorcraft commonly used for offshore and utility missions; the Bell 525 is a modern super‑medium, twin‑engine rotorcraft aimed at executive and offshore roles. The Falcon 8X is a trijet ultra‑long‑range business jet optimized for efficient intercontinental flying, and the G700 is a large‑cabin, ultra‑long‑range business jet focused on maximum cabin volume and comfort. On range, the jets are in a different class: the Falcon 8X is typically around 6,450 nautical miles, and the G700 about 7,500 nautical miles, enabling true intercontinental city pairs. The helicopters are far shorter‑legged: the H225 is roughly in the 450–500 nautical mile range depending on load and reserves, and the Bell 525 is typically around 560 nautical miles. For passenger capacity, the H225 generally carries the most in high‑density layouts (often around 16–19 passengers), the Bell 525 is commonly in the 12–16 range, while the Falcon 8X and G700 are usually configured for about 12–16 and up to roughly 19, respectively, depending on cabin arrangement.
