Beechcraft King Air 360 vs Beechcraft King Air 360er vs Cessna Citation Cj4
The Beechcraft King Air 360 and 360ER are twin‑turboprop aircraft in the light utility/business category, while the Cessna Citation CJ4 is a light business jet. In range terms, the King Air 360 is designed for strong regional missions, but the 360ER extends that capability noticeably, trading some payload flexibility for additional fuel and longer endurance; it is the better choice when you routinely need extra legs without refueling. The Citation CJ4 typically offers higher cruise speeds and a longer nonstop reach than the standard King Air 360, making it more suitable for longer city pairs where time and altitude matter, though real-world range varies with passengers, winds, and reserves. For passenger capacity, both King Air 360 variants generally accommodate around six to nine passengers depending on interior layout, whereas the Citation CJ4 commonly seats about seven to ten in typical business configurations. Overall, the King Air 360 fits short-to-mid missions and varied runway access, the 360ER prioritizes extended turboprop range, and the CJ4 emphasizes speed and jet performance for longer trips.
