Bell 525 Relentless vs Bombardier Global 7500 vs Daher Tbm 960 vs Piper M600 Sls

The Bell 525 Relentless is a fly-by-wire, twin‑engine helicopter aimed at offshore, corporate, and VIP transport. Its typical range is roughly 900–1,000 nautical miles depending on configuration, and it generally seats around 16–20 passengers in high-density layouts (fewer for executive interiors). The Bombardier Global 7500 is an ultra‑long‑range business jet designed for intercontinental missions, offering about 7,700 nautical miles of range and usually carrying 8–19 passengers, with spacious cabin zoning for long-haul comfort. The Daher TBM 960 is a high‑performance single‑engine turboprop optimized for fast point‑to‑point travel from shorter runways; its range is about 1,400–1,700 nautical miles with typical seating for 4–6 (up to 6–7 including a belted lavatory seat, depending on layout). The Piper M600 SLS is a single‑engine turboprop positioned below the TBM for cost and simplicity; it offers roughly 1,200–1,500 nautical miles of range and typically seats about 4–6 passengers.
