Bell 525 Relentless vs Boeing Bbj Max 9 vs Enstrom 480b vs Piaggio Avanti Evo

The Bell 525 Relentless and Enstrom 480B are helicopters, optimized for vertical access rather than long nonstop travel. The Bell 525 is a large, modern super‑medium helicopter typically configured for about 12–16 passengers with a range roughly around 500 nautical miles, making it suited to offshore, corporate shuttles, and point-to-point trips where landing flexibility matters. The Enstrom 480B is a small piston helicopter, usually carrying 3–4 passengers with a range on the order of 250–300 nautical miles, best for short hops, training, and utility missions. The Piaggio Avanti EVO is a turboprop business aircraft, trading runway dependence for much greater speed and range than helicopters. It commonly seats about 6–9 passengers and can fly roughly 1,500–1,800 nautical miles, fitting regional and midsize city-pair business travel. The Boeing BBJ MAX 9 is a VIP airliner-class business jet conversion, offering the longest range and the most cabin volume. While layouts vary widely, it can host dozens in VIP configuration and can reach roughly 6,000+ nautical miles, enabling intercontinental nonstop missions.
