Bell 525 Relentless vs Boeing Bbj Max 9 vs Piper M600 Sls vs Robinson R66

The Bell 525 Relentless and Robinson R66 are helicopters, while the Boeing BBJ MAX 9 and Piper M600 SLS are fixed‑wing aircraft (the BBJ a large airliner‑based business jet; the M600 a single‑engine turboprop). For range, the BBJ MAX 9 is in a different class, typically capable of roughly 6,000+ nautical miles with auxiliary tanks and long‑range corporate configurations, making it suited to intercontinental trips. The Bell 525 is a long‑range helicopter, generally around 500–600 nautical miles depending on reserves and payload. The Piper M600 SLS typically offers around 1,200–1,400 nautical miles, optimized for efficient regional travel. The Robinson R66 is shorter‑range, commonly around 300–350 nautical miles. Passenger capacity also separates them sharply: the BBJ MAX 9 can be outfitted for a wide range but is often configured for roughly 19–50+ passengers in VIP layouts (far more in airline seating). The Bell 525 generally seats about 16–20. The Piper M600 SLS typically seats 5–6. The Robinson R66 usually carries 4–5 occupants including the pilot.
