Beechcraft King Air 360 Er vs Bell 525 Relentless vs Daher Tbm 960 vs Gulfstream G700

The Beechcraft King Air 360ER is a twin‑turboprop business/utility aircraft optimized for short and remote-field operations, with long endurance for its class at roughly 1,500–1,800 nm depending on payload, typically carrying about 6–9 passengers (up to around 11 seats in some layouts). The Daher TBM 960 is a single‑engine turboprop executive aircraft, generally faster than most turboprops and aimed at owner-operators; it typically carries 4–6 passengers in comfort (up to about 6–7 seats) with range around 1,400–1,700 nm. The Bell 525 Relentless is a long‑range fly-by-wire helicopter suited to offshore and corporate missions, usually carrying about 8–12 passengers (higher in transport layouts) with range roughly 500–700 nm, trading speed and range for vertical access. The Gulfstream G700 is an ultra‑long‑range large-cabin business jet, carrying typically 12–16 passengers (up to about 19) with range around 7,500 nm, prioritizing intercontinental nonstop capability and maximum cabin space.
