Enstrom 480b vs Gulfstream G700 vs Leonardo Aw189 vs Robinson R66

The Enstrom 480B and Robinson R66 are light single‑engine helicopters suited to short‑ to mid‑range missions, while the Leonardo AW189 is a larger twin‑engine helicopter designed for longer legs, higher payload, and more demanding offshore or SAR-style operations. The Gulfstream G700 is a long‑range large‑cabin business jet, in a different category entirely, optimized for intercontinental travel at high speed and altitude. In range terms, the G700 is by far the leader, typically capable of roughly 7,000+ nautical miles, enabling nonstop transoceanic routes. The AW189 generally offers a few hundred nautical miles of practical range, commonly around 450–500+ nautical miles depending on configuration and reserves, exceeding most light helicopters. The R66 and Enstrom 480B are shorter‑range by comparison, typically in the roughly 300–350 nautical mile class, varying with fuel, payload, and conditions. Passenger capacity follows the same pattern: the G700 commonly seats around 13–19 passengers in executive layouts; the AW189 is often configured around 16–19 passengers; the R66 typically carries 4 passengers plus a pilot (5 total); and the Enstrom 480B is generally a 5‑seat aircraft including the pilot.
