Beechcraft King Air 360 Er vs Bell 525 Relentless vs Daher Tbm 960 vs Pilatus Pc 24

The Beechcraft King Air 360ER is a twin‑turboprop aircraft aimed at utility and corporate missions, typically carrying about 6–9 passengers with maximum seating often quoted up to around 11. Its headline advantage is endurance and flexibility, with range commonly cited in the roughly 1,500–1,800 nautical mile class depending on payload and reserves. The Bell 525 Relentless is a large fly‑by‑wire helicopter for offshore, VIP, and high‑utility roles. It generally carries about 12–16 passengers depending on configuration, but its range is shorter than the fixed‑wing options, typically on the order of several hundred nautical miles (often around 500–700 nm, mission‑dependent). The Daher TBM 960 is a high‑performance single‑engine turboprop aircraft optimized for owner‑pilot and fast business travel. It usually seats 4–6 passengers in comfort (up to about 6–7 including pilot), with range commonly around 1,400–1,700 nm. The Pilatus PC‑24 is a light business jet designed for versatility, including operation from shorter or less‑prepared runways. It typically accommodates about 6–10 passengers, with range generally around 2,000 nm, giving it the longest reach of the fixed‑wing group here.
