Beechcraft King Air 360 Er vs Enstrom 480b vs Leonardo Aw189 vs Robinson R66

The Beechcraft King Air 360ER is a twin‑turboprop fixed‑wing aircraft aimed at longer regional missions, typically offering the greatest range of this group (roughly up to about 1,500 nautical miles with appropriate reserves and payload tradeoffs) and seating commonly around 6 to 9 passengers depending on interior and weight limits. The Enstrom 480B is a light single‑engine turbine helicopter best suited to shorter trips; its range is generally a few hundred nautical miles (around 350–400 nm) with seating typically for a pilot plus 4 passengers. The Leonardo AW189 is a medium twin‑engine helicopter designed for offshore and utility work; it carries the most people among the helicopters here, commonly 12 to 16 passengers in transport layouts, with range often in the 450–500+ nm class depending on tanks and payload. The Robinson R66 is a light single‑engine turbine helicopter with shorter range (often around 300–350 nm) and seating for a pilot plus 4 passengers.
