Bell 525 Relentless vs Leonardo Aw189 vs Piaggio Avanti Evo vs Pilatus Pc 24
The Bell 525 Relentless and Leonardo AW189 are both twin‑engine, medium class helicopters aimed at offshore, corporate, and utility missions; they trade higher operating flexibility (vertical access) for generally shorter trip legs than fixed‑wing aircraft. In broad terms, the Bell 525 is typically positioned with a slightly longer range than the AW189 depending on fit and reserves, while both commonly seat around the mid‑teens in high‑density layouts and fewer in VIP configurations. The Piaggio Avanti EVO is a twin‑turboprop business aircraft optimized for efficient, relatively fast regional travel. It generally offers longer range than either helicopter and typically carries about 6–9 passengers in an executive cabin. The Pilatus PC‑24 is a twin‑jet “super versatile” light business jet designed for longer point‑to‑point missions and rough/short runway capability. It generally has the longest range of the four and commonly seats about 6–10 passengers in executive layouts, with higher maximum seating possible in commuter-style configurations.
