Bell 525 Relentless vs Gulfstream G700 vs Piper M600 Sls vs Sikorsky S 92

The Bell 525 Relentless and Sikorsky S-92 are large, twin‑engine helicopters aimed at offshore, corporate shuttle, and utility missions, while the Gulfstream G700 is an ultra‑long‑range business jet optimized for intercontinental travel, and the Piper M600 SLS is a single‑engine turboprop for owner‑operators and short to midrange business trips. On range, the G700 is in a different league, capable of roughly 7,000+ nautical miles, enabling nonstop long‑haul city pairs. The M600 SLS offers about 1,400–1,700 nautical miles depending on conditions and reserves, suitable for regional missions. The Bell 525 typically covers on the order of ~500–600 nautical miles, while the S-92 is generally in a similar medium‑range helicopter class (often ~500 nautical miles, configuration dependent). For passenger capacity, the G700 typically seats around 13–19 in executive layouts. The M600 SLS commonly carries 1 pilot plus up to 5 passengers (six seats total). The Bell 525 is often configured around 16–20 passengers, and the S-92 commonly carries roughly 19 passengers, with layouts varying by mission.
