Bell 525 Relentless vs Boeing Bbj Max 9 vs Leonardo Aw189 vs Robinson R66

The Bell 525 Relentless is a large, fly-by-wire twin-engine helicopter aimed at offshore and corporate transport. It typically carries around 16 passengers in a high-density layout (fewer in VIP), with a range on the order of roughly 500–600 nautical miles depending on configuration and reserves. The Leonardo AW189 is also a super-medium twin helicopter, commonly configured for about 16–19 passengers, with broadly similar mission intent and a comparable range band (often cited around 450–550 nautical miles, again varying by fit and fuel planning). The Robinson R66 is a light, single-engine helicopter best suited to short-range utility and private missions; it typically seats 4–5 occupants total and has a much shorter range, roughly around 300 nautical miles. The Boeing BBJ MAX 9 is in a different class entirely: a long-range business jetliner conversion based on the 737 MAX 9. It carries far more people than the helicopters in airline terms, but in BBJ/VIP use it’s usually outfitted for a few dozen passengers, and it offers intercontinental-style legs with ranges commonly quoted around 3,000–3,500+ nautical miles depending on options and payload.
