Bell 525 Relentless vs Bombardier Global 7500 vs Leonardo Aw189 vs Robinson R66

The Bell 525 Relentless and Leonardo AW189 are large, twin‑engine helicopters aimed at offshore, corporate, and government missions, while the Robinson R66 is a much smaller single‑engine helicopter typically used for private, training, and light utility flying. The Bombardier Global 7500 is a long‑range business jet in a different class entirely, designed for intercontinental travel at high speed and altitude. By range, the Global 7500 dominates, offering roughly 7,700 nautical miles, enabling nonstop city pairs that helicopters cannot approach. The Bell 525 and AW189 are broadly comparable medium‑to‑heavy helicopter platforms, typically offering on the order of 450–500 nautical miles depending on payload and reserves. The Robinson R66 is shorter‑legged, commonly around 300 nautical miles, though this varies with fuel, altitude, and loading. Passenger capacity follows mission size: the Global 7500 typically carries about 8–19 passengers in an executive cabin. The AW189 and Bell 525 generally seat around 16–20 depending on configuration. The R66 is limited to about 4 passengers plus a pilot.
