Bell 525 Relentless vs Daher Tbm 960 vs Gulfstream G700 vs Piper M600 Sls
The Bell 525 Relentless is a large, fly-by-wire twin‑engine helicopter aimed at offshore, corporate, and government missions; it typically carries around a dozen-plus passengers in high-density layouts and offers a medium range on the order of a few hundred nautical miles, trading speed and range for vertical access and cabin flexibility. The Daher TBM 960 is a high‑performance single‑engine turboprop airplane in the personal/corporate category, generally seating up to six passengers and delivering long cross‑country capability for its class at roughly 1,500+ nautical miles. The Gulfstream G700 is an ultra‑long‑range large‑cabin business jet designed for intercontinental travel, commonly configured for about 13–19 passengers and offering around 7,500 nautical miles of range. The Piper M600 SLS is a single‑engine turboprop positioned below the TBM in speed and cabin size, typically seating up to five or six occupants and providing about 1,000–1,400 nautical miles depending on configuration and reserves. Overall, the G700 dominates range and cabin, the TBM 960 leads among single turboprops for fast long trips, the M600 SLS targets simpler owner‑pilot missions, and the Bell 525 prioritizes point‑to‑point access without runways.
