Bell 525 Relentless vs Daher Tbm 960 vs Gulfstream G700 vs Piaggio Avanti Evo
The Bell 525 Relentless is a fly-by-wire super‑medium helicopter aimed at offshore, corporate, and emergency missions, trading speed for vertical access; it typically carries around a dozen-plus occupants and offers a practical range on the order of several hundred nautical miles, roughly in the 500–600 nm class depending on configuration. The Daher TBM 960 is a single‑engine turboprop business aircraft optimized for fast owner‑pilot point‑to‑point travel; it usually seats 4–6 in comfort (up to about 7–8 with optional seating) and reaches roughly 1,400+ nm. The Gulfstream G700 is an ultra‑long‑range large‑cabin business jet designed for intercontinental missions; it carries commonly 13–19 passengers (with higher-density layouts possible) and can fly about 7,500 nm. The Piaggio Avanti EVO is a distinctive twin‑turboprop in the light business category with a quiet, efficient cabin; it typically seats 6–8 and offers roughly 1,500–1,800 nm range. Overall, the G700 leads decisively in range and cabin scale, the TBM 960 and Avanti EVO emphasize efficient regional-to-transcontinental trips, and the Bell 525 stands apart for runway independence rather than distance.
