Bell 525 Relentless vs Daher Tbm 960 vs Dassault Falcon 8x vs Piper M600 Sls

The Bell 525 Relentless is a fly-by-wire, super‑medium helicopter aimed at offshore and corporate missions; it typically carries about 16–19 passengers depending on configuration and offers roughly 500–650 nautical miles of range, trading speed for vertical access and point-to-point flexibility. The Daher TBM 960 is a high‑performance single‑engine turboprop airplane in the owner‑pilot segment; it generally seats 4–6 passengers plus a pilot and delivers about 1,400–1,700 nautical miles of range, emphasizing fast, efficient regional travel. The Dassault Falcon 8X is an ultra‑long‑range trijet business jet designed for intercontinental flying; it commonly accommodates 12–16 passengers (with higher-density layouts possible) and can fly around 6,450 nautical miles, prioritizing cabin comfort and global reach. The Piper M600 SLS is a single‑engine turboprop positioned below the TBM in speed and cost; it typically carries 4–6 passengers plus a pilot with approximately 1,200–1,500 nautical miles of range, focusing on simpler, owner‑flown capability.
