Bell 525 Relentless vs Boeing Bbj Max 9 vs Piaggio Avanti Evo vs Pilatus Pc 24
The Bell 525 Relentless is a fly-by-wire, super‑medium helicopter optimized for point-to-point access where runways aren’t available. Its typical range is roughly 500–600 nautical miles, and it generally carries about 12–16 passengers depending on interior and fuel/load tradeoffs. The Boeing BBJ MAX 9 is a long-range VIP airliner based on the 737 MAX 9, aimed at intercontinental missions with airline-level cabin volume. With auxiliary tanks it is typically quoted around 6,000–6,600 nautical miles, and VIP layouts usually seat about 19–50 passengers (far fewer than airline configurations). The Piaggio Avanti EVO is a high-speed turboprop business aircraft emphasizing efficiency and short-to-medium trip economics. Range is commonly around 1,400–1,800 nautical miles, and seating is typically 6–9 passengers. The Pilatus PC-24 is a light business jet designed for versatility, including operation from shorter or less-prepared runways. Range is about 2,000 nautical miles, and it typically carries 6–10 passengers (with higher-density layouts possible).
