Beechcraft King Air 360 Er vs Daher Tbm 960 vs Leonardo Aw189 vs Piper M600 Sls

The Beechcraft King Air 360ER and Daher TBM 960 are pressurized fixed‑wing turboprops, while the Piper M600 SLS is a pressurized single‑engine turboprop positioned below the TBM in speed and cabin size; the Agusta/Leonardo AW189 is a twin‑engine helicopter optimized for vertical access rather than point‑to‑point cruise efficiency. In range, the King Air 360ER is generally the longest‑leg option of this group (roughly up to about 1,800 nautical miles depending on configuration), the TBM 960 follows with long single‑engine legs (around the 1,400–1,700 nm class), the M600 SLS is shorter (about the 1,000–1,500 nm class), and the AW189 typically offers the shortest point‑to‑point range among these (often in the few‑hundred‑nautical‑mile class, mission dependent). For passenger capacity, the King Air 360ER usually seats the most in a typical cabin layout (commonly 6–9), the AW189 can carry a comparable or higher headcount in high‑density configurations (often up to the mid‑teens), while the TBM 960 and M600 SLS are typically 4–6 passenger aircraft plus pilot, with the TBM offering a larger, faster premium single‑engine experience.
