Beechcraft King Air 360 Er vs Enstrom 480b vs Robinson R66 vs Sikorsky S 92

The Beechcraft King Air 360ER is a fixed‑wing twin‑turboprop business/utility aircraft optimized for longer point‑to‑point travel. It typically carries about 6 to 9 passengers depending on interior and offers long range on the order of roughly 1,500–2,000+ nautical miles, making it the best fit here for regional to near‑transcontinental missions from airports. The Enstrom 480B and Robinson R66 are light single‑turbine helicopters suited to short‑range utility, training, patrol, and personal/charter work, with typical seating around 4 to 5 passengers. Their practical range is generally a few hundred nautical miles, with the R66 often in the ~300+ nm class and the 480B in a similar short‑range bracket, varying with payload and reserves. The Sikorsky S‑92 is a medium twin‑turbine transport helicopter built for offshore, SAR, and high‑capacity passenger movement. It commonly seats around 19 passengers and offers medium range, typically several hundred nautical miles, prioritizing payload, redundancy, and mission equipment over long cruise range.
