Cessna 208b Grand Caravan Ex vs Enstrom 480b vs Leonardo Aw189 vs Robinson R66

The Cessna 208B Grand Caravan EX is a single‑engine turboprop fixed‑wing utility aircraft, typically offering the longest practical range in this group and the highest passenger capacity, commonly configured around 9 passengers (more in commuter layouts) plus crew, making it best suited to longer point‑to‑point regional legs and cargo/passenger haul. The Enstrom 480B is a light single‑engine piston helicopter with relatively short range and low capacity, generally around 4 passengers plus pilot, oriented to training, patrol, and short‑hop utility work rather than transport efficiency. The Agusta/Leonardo AW189 is a medium twin‑engine turbine helicopter, designed for offshore and SAR/utility roles, with substantially greater range and payload than the light helicopters and a much higher passenger capacity, typically in the mid‑teens (often up to about 16–19 depending on configuration). The Robinson R66 is a light single‑engine turbine helicopter with modest range and capacity, typically about 4 passengers plus pilot, offering more speed and turbine reliability than piston lights but far less capacity and range than the AW189 and generally less transport efficiency than the Caravan for longer routes.
