Bell 525 Relentless vs Leonardo Aw609 Tiltrotor vs Sikorsky S 92

The Bell 525 Relentless and Sikorsky S‑92 are conventional twin‑engine helicopters, while the Leonardo AW609 is a tiltrotor that flies like a helicopter for takeoff and landing but transitions to airplane‑like forward flight. In typical missions, the AW609 is aimed at faster point‑to‑point travel and generally offers a longer range than most helicopters in its class, often cited around 700–800 nautical miles depending on payload and reserves. The Bell 525 targets the “super‑medium” helicopter category with a typical range in the mid‑400 nautical mile class and is optimized for offshore and corporate transport. The Sikorsky S‑92 is a larger “heavy” helicopter used extensively for offshore oil and gas and SAR, with a typical range roughly in the 500 nautical mile class, varying widely by configuration. For passenger capacity, the AW609 is usually configured for about 6–9 passengers. The Bell 525 is commonly cited around 16–20 passengers in high‑density layouts. The S‑92 generally carries the most, often configured around 19 passengers for offshore transport, with other layouts possible.
