Bell 525 Relentless vs Boeing Bbj Max 9 vs Bombardier Global 7500 vs Piaggio Avanti Evo
The Bell 525 Relentless is a super‑medium helicopter, optimized for vertical access to remote sites and city centers rather than long-distance travel. It typically carries around 12–16 passengers in an executive layout and has a range on the order of roughly 500–600 nautical miles, depending on mission profile and reserves. The Piaggio Avanti EVO is a high-speed turboprop business aircraft suited to short-to-medium regional trips. It generally seats about 6–9 passengers and offers roughly 1,400–1,800 nautical miles of range, varying with payload and speed. The Boeing BBJ MAX 9 is a large, long-range VIP airliner platform. In business/VIP configurations it often carries roughly 25–50 passengers (more if densified) and can reach about 6,000–6,500 nautical miles. The Bombardier Global 7500 is an ultra-long-range purpose-built business jet, typically seating about 14–19 passengers and offering about 7,700 nautical miles of range, making it the longest-range option among these.
