Airbus Helicopters H225 vs Beechcraft King Air 360 Er vs Leonardo Aw189 vs Piper M600 Sls

The Airbus H225 and Leonardo AW189 are large, twin‑engine helicopters built for offshore transport and utility missions, carrying roughly 16–19 passengers depending on configuration. Their practical range is typically a few hundred nautical miles, often around 400–500 nm in passenger operations, with the AW189 generally comparable and sometimes slightly longer‑legged depending on fuel fit and payload. The Beechcraft King Air 360ER is a twin‑turboprop, fixed‑wing aircraft oriented to longer point‑to‑point travel at higher cruise speeds and altitudes than helicopters. It typically seats about 8–11 passengers in corporate layouts and offers substantially greater range, commonly on the order of 1,500–1,800+ nm depending on payload and reserves. The Piper M600 SLS is a single‑engine turboprop in a smaller business category, usually configured for 4–6 passengers. Its range is generally around 1,200–1,500 nm, placing it below the 360ER but well above the helicopters, with lower operating complexity but less redundancy than twin‑engine types.
