Beechcraft King Air 360 Er vs Bell 525 Relentless vs Piaggio Avanti Evo vs Pilatus Pc 24
The Beechcraft King Air 360ER, Bell 525 Relentless, Piaggio Avanti EVO, and Pilatus PC-24 span different categories: the King Air 360ER and Avanti EVO are pressurized twin‑turboprop airplanes, the PC-24 is a twin‑jet light business jet, and the Bell 525 is a long‑range, fly‑by‑wire helicopter. In range, the PC-24 generally leads among the fixed‑wing options, typically around 2,000 nautical miles class depending on load and reserves, while the King Air 360ER and Avanti EVO sit in the mid‑to‑upper turboprop bracket, commonly in the roughly 1,400–1,800 nautical miles class, again mission‑dependent. The Bell 525’s range is typically in the roughly 500–700 nautical miles class, but it trades cruise efficiency for point‑to‑point flexibility, including direct access to helipads and unimproved sites. For passenger capacity, the PC-24 and King Air 360ER are commonly configured for about 6–9 passengers, the Avanti EVO similarly about 6–8, while the Bell 525 is typically arranged for around 10–16 passengers depending on seating and mission fit.
