Bell 525 Relentless vs Bombardier Global 7500 vs Dassault Falcon 8x vs Piper M600 Sls
The Bell 525 Relentless is a fly-by-wire, twin‑engine helicopter aimed at offshore, corporate, and government missions; compared with the jets it trades speed and altitude for vertical lift and point‑to‑point access, with a typical range around 500–600 nautical miles and seating commonly configured around 12–16 passengers depending on layout. The Bombardier Global 7500 is an ultra‑long‑range business jet designed for intercontinental city pairs, offering roughly 7,700 nautical miles of range and typically carrying about 14–19 passengers in multi‑zone cabin configurations. The Dassault Falcon 8X is also an ultra‑long‑range business jet, optimized for efficiency and runway flexibility, with about 6,450 nautical miles of range and typical seating around 12–16 passengers. The Piper M600 SLS is a single‑engine turboprop for owner‑pilots and short to medium trips; it is far smaller and slower than the jets, with about 1,400 nautical miles of range and seating for up to 6 occupants.
