Bell 525 Relentless vs Boeing Bbj Max 9 vs Piaggio Avanti Evo vs Robinson R66

The Bell 525 Relentless is a fly-by-wire, super‑medium helicopter aimed at executive and offshore missions; it typically carries around 12–16 passengers depending on layout, with a practical range on the order of roughly 500–600 nautical miles. The Robinson R66 is a much smaller, light single‑turbine helicopter suited to personal or utility flying; it seats about 4–5 including the pilot and has a much shorter range, roughly 300–350 nautical miles. The Piaggio Avanti EVO is a high‑speed, pressurized twin‑turboprop business aircraft; it generally seats 6–9 passengers and offers regional range, commonly around 1,400–1,800 nautical miles depending on reserves, payload, and conditions. The Boeing BBJ MAX 9 is a large VIP airliner based on the 737 MAX 9; it can be configured for very high passenger counts in airline form but, as a BBJ, is typically outfitted for perhaps a few dozen passengers in premium layouts, and it provides intercontinental range, roughly 6,000+ nautical miles.
