Bell 525 Relentless vs Boeing Bbj Max 9 vs Pilatus Pc 24 vs Piper M600 Sls
The Bell 525 Relentless is a fly-by-wire, super‑medium helicopter aimed at point-to-point missions without runways; it typically carries around a dozen-plus passengers in an executive layout and offers roughly 500–600 nautical miles of range depending on payload and reserves. The Boeing BBJ MAX 9 is a long-range VIP airliner conversion in a completely different class: it can be outfitted for a few dozen passengers in high-end corporate layouts (and far more in airline seating) and is built for intercontinental legs, roughly in the 3,000+ nautical mile range with typical business-jet mission payloads. The Pilatus PC‑24 is a light jet designed for versatility, including operation from shorter and semi-prepared runways; it commonly seats about 6–10 passengers and has about 1,800–2,000 nautical miles of range. The Piper M600 SLS is a single‑engine turboprop for owner-operators; it usually carries 1 pilot plus about 4–5 passengers and has roughly 1,400–1,600 nautical miles of range. Overall, BBJ MAX 9 leads on capacity and long-haul reach, PC‑24 balances speed and access, M600 emphasizes simplicity and efficiency, and Bell 525 prioritizes vertical access over distance.
