Beechcraft King Air 360 Er vs Bell 525 Relentless vs Piaggio Avanti Evo vs Sikorsky S 92

The Beechcraft King Air 360ER and Piaggio Avanti EVO are pressurized twin‑turboprop airplanes best suited to regional missions, while the Bell 525 Relentless and Sikorsky S‑92 are twin‑engine helicopters optimized for point‑to‑point access without runways. In range, the King Air 360ER is typically the longest‑legged of the group, reaching roughly 1,500–1,800 nautical miles depending on payload and reserves. The Avanti EVO generally offers slightly less, often around 1,200–1,500 nautical miles. Helicopters trade cruise efficiency for vertical lift: the Bell 525 commonly falls in the ~500–600 nautical mile class, whereas the larger S‑92 is often in the ~450–550 nautical mile class, mission‑equipped. For passenger capacity, the King Air 360ER and Avanti EVO are usually configured for about 6–9 passengers in executive layouts. The Bell 525 typically seats around 12–16 depending on cabin arrangement. The Sikorsky S‑92 is the capacity leader, commonly carrying about 16–19 passengers (and more in high‑density configurations).
