Airbus Helicopters H225 vs Bell 525 Relentless vs Leonardo Aw189 vs Leonardo Aw609 Tiltrotor vs Sikorsky S 92

Airbus Helicopters’ H225 and Sikorsky’s S‑92 sit in the heavy/large medium twin category used widely for offshore transport and SAR. Both typically carry around 19 passengers in high-density seating (with room for fewer in more spacious layouts) and offer long, practical offshore ranges on the order of roughly 450–600 nautical miles depending on reserves, payload, and configuration. Bell’s 525 Relentless is a modern “super‑medium” twin aimed at similar missions, generally in the 16–19 passenger class, with comparable offshore reach often cited around the 500 nautical mile neighborhood. Leonardo’s AW189 is a large medium twin, usually configured for about 16–19 passengers, and delivers solid offshore range broadly similar to the 525, commonly in the ~450–500 nautical mile class. Leonardo’s AW609 is different: it’s a tiltrotor rather than a conventional helicopter, typically carrying about 6–9 passengers, but trading cabin capacity for much higher cruise speed and longer point‑to‑point range, often roughly 700 nautical miles or more in mission-dependent planning.
