Airbus Helicopters H225 vs Bell 525 Relentless vs Boeing Bbj Max 9 vs Robinson R66

The Airbus H225 and Bell 525 Relentless are large, long-range twin‑engine helicopters aimed at offshore, search-and-rescue, and high-end utility/VIP missions. The H225 generally offers higher maximum seating in transport layouts (often around the high‑teens to mid‑20s) and long overwater endurance, while the Bell 525 targets similar missions with a modern fly‑by‑wire design and a typical seating range in the mid‑teens to around 20, with range also in the long‑haul helicopter class (roughly 500–700 nm depending on fit and reserves). The Boeing BBJ MAX 9 is in a different category entirely: a long-range narrowbody business jet derivative designed for intercity and intercontinental legs, typically configured for a few dozen passengers in VIP layouts, with range on the order of several thousand nautical miles (about 3,000+ nm). The Robinson R66 is a light single‑engine helicopter for short-hop transport and utility work, carrying about 4 passengers plus a pilot (around five seats total) with a much shorter range, typically a few hundred nautical miles.
