Beechcraft King Air 360 Er vs Enstrom 480b vs Leonardo Aw189 vs Piper M600 Sls

The Beechcraft King Air 360ER and Piper M600 SLS are fixed‑wing turboprops, while the Enstrom 480B and Leonardo AW189 are helicopters; that alone drives big differences in range, speed, and cabin capacity. The King Air 360ER sits in the twin‑engine business turboprop category and typically offers the longest practical range of this group, on the order of roughly 1,500–1,800 nautical miles depending on payload and reserves, with seating commonly arranged for about 6–9 passengers. The Piper M600 SLS is a single‑engine personal/owner‑pilot turboprop: it generally carries about 1 pilot plus 5 passengers (up to 6 seats total) and has a range commonly around 1,000–1,400 nautical miles. The Enstrom 480B is a light single‑engine helicopter used for utility and training; it typically seats about 4–5 total and has a much shorter range, roughly a few hundred nautical miles. The AW189 is a larger, medium twin helicopter aimed at offshore and SAR/utility missions; it can carry markedly more people, often around 16–19 passengers in transport layouts, with range typically in the mid‑hundreds of nautical miles.
