Beechcraft King Air 360 Er vs Leonardo Aw189 vs Piper M600 Sls vs Robinson R66

The Beechcraft King Air 360ER is a twin‑turboprop fixed‑wing aircraft optimized for efficient regional transport. It offers the longest reach of this group at roughly 1,500 nautical miles (configuration dependent) and typically carries about 6 to 9 passengers plus crew, making it well suited to longer point‑to‑point trips. The Piper M600 SLS is a single‑engine turboprop fixed‑wing aircraft aimed at owner‑operators; it is shorter‑range than the King Air at about 1,100–1,200 nautical miles and generally seats up to 5 passengers plus a pilot. The Leonardo AW189 is a large twin‑engine helicopter designed for offshore and utility missions; its range is commonly around 450–500 nautical miles and it can carry roughly 12 to 16 passengers depending on interior and mission fit. The Robinson R66 is a lighter single‑turbine helicopter focused on cost‑effective utility and private use; it has the shortest range here at about 300–350 nautical miles and typically carries 4 passengers plus a pilot.
