Beechcraft King Air 360 Er vs Cessna Citation Xls vs Leonardo Aw189 vs Piper M600 Sls

The Beechcraft King Air 360ER and Piper M600 SLS are pressurized turboprops, the Cessna Citation XLS+ is a light-to-midsize business jet, and the Agusta/Leonardo AW189 is a twin‑engine helicopter focused on vertical lift missions. In range terms, the King Air 360ER is typically the longest‑legged of this group, commonly planned around roughly 1,500–1,800 nautical miles depending on load and reserves, while the Citation XLS+ generally offers about 1,700–2,100 nautical miles with higher cruise speeds than the turboprops. The Piper M600 SLS is shorter‑range, often planned around about 1,000–1,500 nautical miles, trading cabin size for lower operating complexity and cost. The AW189’s range is mission‑dependent and usually far lower than the fixed‑wing aircraft, commonly on the order of a few hundred nautical miles, but it uniquely offers point‑to‑point access without runways. For passengers, the King Air 360ER and Citation XLS+ typically seat about 6–9 in executive layouts, the M600 SLS usually carries about 4–6 passengers plus a pilot, and the AW189 can carry around 16–19 in high‑density seating (or fewer in VIP/mission configurations).
