Bell 525 Relentless vs Gulfstream G700 vs Pilatus Pc 24 vs Piper M600 Sls

The Bell 525 Relentless is a fly-by-wire super‑medium helicopter optimized for point-to-point access into constrained sites; it typically carries around 12–16 passengers depending on configuration, with a range on the order of roughly 500–600 nautical miles. The Gulfstream G700 is an ultra‑long‑range large‑cabin business jet built for intercontinental missions, generally seating about 10–19 passengers, with published range around 7,500 nautical miles. The Pilatus PC‑24 is a light jet designed for versatility and shorter or semi‑prepared runways; it commonly carries about 6–10 passengers in executive layouts, with range roughly around 2,000 nautical miles. The Piper M600 SLS is a single‑engine turboprop aimed at owner‑operators, typically seating 1 pilot plus about 4–5 passengers, with range roughly around 1,400–1,500 nautical miles. In practical terms, the G700 dominates range and cabin volume, the PC‑24 balances jet speed with access, the M600 SLS prioritizes simplicity and operating economy, and the Bell 525 trades cruise speed for vertical access and mission flexibility.
