Airbus Helicopters H225 vs Bell 525 Relentless vs Pilatus Pc 24 vs Piper M600 Sls

The Airbus H225 and Bell 525 Relentless are large, twin‑engine helicopters aimed at offshore, SAR, and utility missions. The H225 is the heavier, higher‑capacity option, typically carrying roughly 16–19 passengers in transport layouts, with range commonly in the ~450–550 nm class depending on fuel and mission equipment. The Bell 525 is a slightly smaller, newer‑generation super‑medium, usually configured around 12–16 passengers, with range often cited around ~500–560 nm. The Pilatus PC‑24 is a twin‑engine light jet built for flexible operations, including short and semi‑prepared runways, and typically seats 6–10 passengers depending on interior and crew. Its range is in the ~1,900–2,000 nm class, making it a step up from helicopters for point‑to‑point travel. The Piper M600 SLS is a single‑engine turboprop for owner‑operators, generally seating about 4–6 passengers, with range around ~1,400–1,500 nm. In short, H225/525 emphasize vertical lift and access, while PC‑24 and M600 prioritize speed and longer stage lengths.
