The Bell 525 Relentless and MD Helicopters (McDonnell Douglas) 902 Explorer are helicopters, while the Gulfstream G700 and Piper M600 SLS are fixed‑wing airplanes. In category and mission, the Bell 525 is a large, long‑range, fly‑by‑wire super‑medium helicopter aimed at offshore and corporate transport; the MD 902 is a lighter twin helicopter optimized for utility, EMS, and shorter corporate hops. The Gulfstream G700 is an ultra‑long‑range business jet designed for intercontinental travel, high speed, and a true large‑cabin experience. The Piper M600 SLS is a single‑engine turboprop focused on owner‑pilot operations and efficient regional travel. On range, the G700 is by far the longest, roughly around 7,000+ nautical miles. The M600 SLS is in the mid range for personal aircraft, roughly around 1,500 nautical miles. The Bell 525 typically sits around the ~500–600 nautical mile class, while the MD 902 is shorter, often roughly ~300–400 nautical miles depending on configuration. For passenger capacity, the G700 can carry the most (typically 10–19), the Bell 525 generally carries about 16–19, the MD 902 about 8–10, and the M600 SLS typically seats 5–6.
