Bell 525 Relentless vs Daher Tbm 960 vs Pilatus Pc 24 vs Piper M600 Sls
The Bell 525 Relentless is a fly-by-wire, super‑medium helicopter aimed at offshore, corporate, and utility missions. It typically carries around a dozen-plus occupants depending on layout and trades airplane-like cruise range for vertical access; practical range is on the order of several hundred nautical miles, often roughly 500–700 nm with reserves. The Daher TBM 960 is a high-performance, single‑engine turboprop airplane optimized for fast, efficient owner-operator travel. It is usually configured for about 4–6 passengers plus a pilot and offers long legs, commonly around 1,200–1,700 nm depending on power settings and payload. The Pilatus PC‑24 is a light business jet designed for versatility, including operation from shorter and rougher runways than many jets. It typically seats about 6–10 passengers and delivers jet mission range broadly around 1,800–2,000 nm with typical loads. The Piper M600 SLS is a pressurized, single‑engine turboprop positioned below the TBM in speed and price. It generally carries about 4–5 passengers plus a pilot and offers mid-to-long range, commonly around 1,000–1,400 nm depending on loading and conditions.
