Bell 525 Relentless vs Leonardo Aw189 vs Md Helicopters (mcdonnell Douglas) 902 Explorer vs Piaggio Avanti Evo

The Bell 525 Relentless and Leonardo AW189 are both modern, medium twin-engine helicopters aimed at offshore, SAR, and corporate shuttle missions; they sit in a similar category and typically offer the greatest practical passenger capacity of the group, commonly configured around the mid-teens (often about 16–19) with ranges generally in the 450–500+ nautical mile class depending on fit and reserves. The MD Helicopters (McDonnell Douglas) 902 Explorer is a lighter twin helicopter optimized for lower operating costs and urban operations; it carries fewer passengers (typically around 8–10) and generally has a shorter range (roughly 300+ nautical miles). The Piaggio Avanti EVO is not a helicopter but a pressurized twin‑turboprop airplane; it trades vertical lift for higher cruise speed and longer legs, typically carrying about 6–9 passengers with a range commonly around 1,000+ nautical miles, making it better for point‑to‑point regional travel where runways are available. Overall, AW189 and Bell 525 lead on rotorcraft capacity and mission flexibility, the MD 902 is the smaller/shorter‑range rotor option, and the Avanti EVO leads on range and cruise efficiency.
