Beechcraft King Air 360 Er vs Bell 525 Relentless vs Daher Tbm 960 vs Sikorsky S 92

The Beechcraft King Air 360ER and Daher TBM 960 are pressurized turboprop fixed‑wing aircraft, while the Bell 525 Relentless and Sikorsky S‑92 are twin‑engine helicopters. In category, the TBM 960 is a high‑performance single‑engine turboprop typically used as an owner‑flown or small corporate aircraft; the King Air 360ER is a larger twin‑turboprop aimed at corporate, utility, and special‑mission roles. The Bell 525 and S‑92 are medium/large transport helicopters suited to offshore, VIP, and search‑and‑rescue style missions, trading cruise efficiency for vertical access. On range, the fixed‑wing turboprops generally go farther per unit fuel than the helicopters: the King Air 360ER and TBM 960 are commonly cited around the ~1,500–1,800 nautical mile class depending on payload and reserves, whereas the Bell 525 is roughly around the ~500–700 nautical mile class and the S‑92 is typically in a similar ~500–600+ nautical mile class depending on configuration. For passenger capacity, the TBM 960 usually seats about 4–6 passengers, the King Air 360ER about 6–9, the Bell 525 about 12–16, and the Sikorsky S‑92 about 19 passengers (with higher-density layouts possible for utility missions).
