Cessna 208b Grand Caravan Ex vs Enstrom 480b vs Piaggio Avanti Evo vs Robinson R66

The Cessna 208B Grand Caravan EX is a single‑engine turboprop utility airplane, typically offering the longest practical range of this group (roughly 900–1,000+ nm depending on load) and the highest passenger capacity, commonly configured for about 9 passengers (more seats possible in some layouts). The Piaggio Avanti EVO is a twin‑engine turboprop business aircraft, generally delivering long range similar to or exceeding the Caravan in many missions (often around 1,300–1,700 nm) with a typical executive cabin for about 6–8 passengers and higher cruise speed than the others. The Enstrom 480B is a single‑engine piston helicopter, suited to short to moderate trips with a much shorter range (about 300–400 nm) and a small cabin, usually around 4 passengers plus a pilot depending on configuration and loading. The Robinson R66 is a single‑engine turbine helicopter with range in the same general class as the Enstrom but often a bit higher (about 300–400+ nm), and it typically carries about 4 passengers plus a pilot. Actual range and seating vary by equipment, reserves, payload, and operating conditions.
