Airbus Helicopters H225 vs Bell 525 Relentless vs Embraer Legacy 650 E vs Piper M600 Sls

The Airbus H225 and Bell 525 Relentless are large twin‑engine helicopters oriented to offshore, SAR, and utility missions rather than point‑to‑point business travel. The H225 typically carries around 19 passengers (high‑density layouts) with a practical range on the order of 450–500 nm, while the Bell 525 is generally configured for about 16–20 passengers with a similar roughly 500+ nm class range depending on reserves and mission profile. The Embraer Legacy 650E is a long‑range, large‑cabin business jet designed for intercity and intercontinental flying, seating up to 13–14 passengers in typical executive layouts and offering about 3,900 nm of range, enabling nonstop missions such as U.S. coast‑to‑coast and many transatlantic pairings. The Piper M600 SLS is a single‑engine turboprop in the owner‑flown/managed‑operation segment, usually carrying 4–6 passengers (up to 6 plus pilot) with roughly 1,400–1,600 nm range, prioritizing efficiency and access to shorter runways over maximum cabin volume.
