Beechcraft King Air 360 vs Leonardo Aw109 Trekker vs Pilatus Pc 12 Ngx vs Piper M600 Sls

By category, the Beechcraft King Air 360 and Pilatus PC-12 NGX are pressurized single-aisle turboprop airplanes aimed at corporate and utility missions; the King Air is twin‑engine for redundancy and higher multi‑engine performance, while the PC‑12 is a high‑performance single with strong short/rough‑field capability. The Piper M600 SLS is a lighter, pressurized single‑engine turboprop positioned closer to owner‑pilot personal travel than full corporate utility. The Leonardo AW109 Trekker is a light twin‑engine helicopter, trading fixed‑wing cruise efficiency for vertical access and point‑to‑point flexibility. On range, the King Air 360 and PC‑12 NGX generally lead among these for typical business missions, with the PC‑12 NGX often cited around the ~1,800‑nm class and the King Air 360 in a similar long‑range bracket depending on payload and reserves. The M600 SLS is shorter‑legged, roughly in the ~1,400–1,500‑nm class. The AW109 Trekker’s practical range is usually the shortest of the group, roughly in the ~400–500‑nm class. For passenger capacity, the King Air 360 and PC‑12 NGX commonly seat about 6–9 in executive layouts. The M600 SLS typically carries about 4–6 passengers plus pilot. The AW109 Trekker usually carries about 5–6 passengers plus one or two pilots.
