Beechcraft King Air 260 vs Beechcraft King Air 360er vs Pilatus Pc 12 Ngx vs Piper M600 Sls

The Beechcraft King Air 260 and 360ER are twin‑turboprop business aircraft, while the Pilatus PC‑12 NGX and Piper M600 SLS are single‑engine turboprops aimed at owner‑operators and utility/business missions. In range, the King Air 360ER is the long‑leg specialist, offering significantly more endurance than the King Air 260 and generally exceeding the typical range of the PC‑12 NGX and M600 SLS for longer overwater or remote operations. The King Air 260 provides solid midsize business‑turboprop range, usually less than the 360ER but competitive for regional trips. The PC‑12 NGX is known for strong real‑world range among singles, often comparable to or better than many light twins on typical loads, while the M600 SLS is usually shorter‑ranged than the PC‑12 NGX and the 360ER, optimized for simpler, faster owner flying. For passenger capacity, both King Air models typically seat more people in standard configurations (often around 8–9 passengers) with flexible cabin layouts; the PC‑12 NGX is commonly configured around 6–8 passengers; the M600 SLS typically carries fewer (often around 4–6 passengers) depending on interior and payload.
