Beechcraft King Air 360 Er vs Enstrom 480b vs Piper M600 Sls vs Robinson R66

The Beechcraft King Air 360ER is a pressurized, twin‑turboprop fixed‑wing aircraft aimed at corporate and special‑mission use; it offers the longest range of the group (roughly 1,500–1,800 nm depending on payload and reserves) and typically carries about 6–9 passengers in an executive layout (more in special configurations). The Piper M600 SLS is a single‑engine turboprop fixed‑wing aircraft for owner‑operators; it has long range for its class (about 1,200–1,400 nm) and usually seats 1 pilot plus up to 5 passengers. The Robinson R66 is a light single‑engine turbine helicopter; it trades speed and range for vertical access, typically flying about 300–350 nm with reserves and carrying a pilot plus up to 4 passengers. The Enstrom 480B is also a light single‑engine turbine helicopter; it’s broadly similar in mission to the R66 with comparable passenger capacity (pilot plus up to 4) and generally similar or somewhat shorter real‑world range (often around 250–350 nm), depending heavily on fuel, load, and operating conditions.
