Beechcraft King Air 360 Er vs Enstrom 480b vs Leonardo Aw189 vs Piaggio Avanti Evo

The Beechcraft King Air 360ER and Piaggio Avanti EVO are pressurized twin‑turboprop airplanes, while the Enstrom 480B and Leonardo AW189 are helicopters, with the AW189 being a larger, offshore‑class twin and the 480B a light single. In range, the King Air 360ER is typically the longest‑legged of the group, designed for extended missions and often offering roughly 1,500+ nautical miles depending on configuration and reserves. The Avanti EVO is also a long‑range turboprop, commonly around the 1,400–1,700 nautical mile class, with higher cruise speed than most turboprops. Helicopter range is generally shorter: the AW189 is optimized for medium‑range transport and SAR/offshore work, typically in the several‑hundred‑nautical‑mile bracket (often roughly 450–500 nm plus reserves depending on fit), while the Enstrom 480B is usually closer to roughly 300–350 nm. For passenger capacity, the AW189 carries the most, commonly up to around 16–19 passengers in high‑density layouts. The King Air 360ER and Avanti EVO are usually configured for about 6–9 passengers. The Enstrom 480B typically seats about 4–5 including the pilot.
