Bell 525 Relentless vs Boeing Bbj Max 9 vs Leonardo Aw189 vs Piaggio Avanti Evo
The Bell 525 Relentless and Leonardo AW189 are twin‑engine helicopters, while the Boeing BBJ MAX 9 and Piaggio Avanti EVO are fixed‑wing aircraft, with the BBJ MAX 9 being a large VIP airliner and the Avanti EVO a smaller business turboprop. For range, the BBJ MAX 9 is in a different class, typically capable of roughly 6,000+ nautical miles with auxiliary tanks and VIP fit, suited to intercontinental missions. The Avanti EVO generally offers around 1,700–1,800 nautical miles, aimed at regional and transcontinental light business travel. Helicopter ranges are much shorter: the AW189 is commonly around 450–500 nautical miles, and the Bell 525 is broadly similar, often cited in the roughly 500–600 nautical mile bracket depending on reserves and payload. Passenger capacity also separates them: a BBJ MAX 9 can be configured very flexibly but often carries roughly 25–50 passengers in VIP layouts (far more in airline seating). The Avanti EVO typically seats about 7–9. The AW189 usually carries about 16–19, while the Bell 525 is typically around 12–16 depending on configuration.
