The King Air 360 leads, topping 5 of 7 compared metrics.
Cross-shopping the Beechcraft / Textron Aviation King Air 360 (introduced 2021) against the Daher (TBM) TBM 850 (introduced 2006) is a common decision, and the two sit closer on paper than the badges suggest. Both are turboprops, which makes them natural cross-shopping rivals. The clearest separation between them is cabin capacity, where the King Air 360 carries more passengers. We line the numbers up below, then translate them into the mission each aircraft actually wins.

- The King Air 360 delivers 83% more passenger capacity (King Air 360: 11 seats; TBM 850: 6 seats).
- The King Air 360 is the newer design (introduced 2021 versus 2006 for the TBM 850), a gap of 15 years that usually shows up in avionics, cabin systems and fuel burn.
- The King Air 360 is the larger aircraft by maximum takeoff weight (15,000 lbs versus 7,394 lbs), which typically buys more cabin and payload at the cost of higher trip economics.

Which mission suits which aircraft
The King Air 360 is the stronger fit for transcontinental missions — its 2,539 nm of range removes fuel stops on those legs. The TBM 850, at 1,665 nm, is better matched to regional and short-to-medium legs, where lower trip cost counts for more than outright reach. If most of your flying sits inside the TBM 850's range, the King Air 360's extra capability is range you pay to carry but rarely use.
Which should you choose?
On published specifications the King Air 360 leads on both range and cabin capacity, so it suits operators who want maximum mission flexibility from a single airframe. The TBM 850 can still be the smarter buy on acquisition cost, operating economics, runway performance, or current availability — the factors that rarely show up in a spec sheet. Our acquisition advisory team can model both against your actual mission profile before you commit.
