Bell 525 Relentless vs Cessna Citation Xls vs Leonardo Aw189 vs Robinson R66

The Bell 525 Relentless and Leonardo AW189 are modern, twin‑engine medium helicopters aimed at offshore, corporate, and utility roles, while the Robinson R66 is a lighter, single‑engine helicopter primarily for private, training, and light commercial use. The Cessna Citation XLS+ is a twin‑engine business jet designed for fast point‑to‑point travel between airports rather than vertical-lift missions. In range, the Citation XLS+ typically offers the longest, commonly around 2,000+ nautical miles depending on payload and reserves, making it best for regional-to-transcontinental trips. The Bell 525 and AW189 generally sit in the mid-hundreds of nautical miles, often roughly 400–500 nm in typical configurations, suited to offshore legs and regional helicopter transport. The Robinson R66 is usually shorter-range than the larger twins, commonly a few hundred nautical miles. For passenger capacity, the AW189 and Bell 525 are the highest, often configured around 12–16 passengers depending on mission and layout. The Citation XLS+ typically seats about 7–9 passengers in executive configuration. The Robinson R66 is smallest, generally carrying about 4 passengers plus a pilot.
