Beechcraft King Air 360 Er vs Enstrom 480b vs Pilatus Pc 24 vs Robinson R66

By category, the Beechcraft King Air 360ER and Pilatus PC-24 are both pressurized, turbine business aircraft, but the 360ER is a twin‑turboprop while the PC-24 is a twin‑jet light business jet. The Enstrom 480B and Robinson R66 are single‑engine turbine helicopters, typically used for utility, training, patrol, and light charter roles rather than fast point‑to‑point business travel. On range, the King Air 360ER is generally the longest‑legged of the group, designed for extended turboprop missions. The PC-24 offers long business-jet range, usually less than the 360ER in maximum ferry terms but with higher cruise speed. The R66 and 480B have much shorter ranges than the fixed‑wing aircraft, with the R66 typically able to fly farther than the 480B depending on configuration and reserves. On passenger capacity, the PC-24 and King Air 360ER can be configured for roughly 6 to 9 passengers in typical executive layouts, while the R66 commonly carries about 4 passengers plus a pilot and the 480B about 4 passengers plus a pilot, subject to weight and mission equipment.
