Bell 525 Relentless vs Daher Tbm 960 vs Piaggio Avanti Evo vs Sikorsky S 92

The Bell 525 Relentless and Sikorsky S-92 are large, twin‑engine helicopters aimed at offshore, corporate, and utility transport, while the Daher TBM 960 is a high‑performance single‑engine turboprop airplane optimized for owner‑pilots and fast point‑to‑point travel, and the Piaggio Avanti EVO is a twin‑turboprop business airplane focused on cabin comfort and jet‑like cruise efficiency. On range, fixed‑wing aircraft generally go farther: the TBM 960 and Avanti EVO typically deliver about 1,000–1,700 nautical miles depending on reserves, payload, and speed settings, making them better suited to longer nonstop trips. The Bell 525 is typically in the several‑hundred‑nautical‑mile class (roughly ~500–700 nm depending on configuration), while the larger S‑92 is also generally in the several‑hundred‑nautical‑mile range and often optimized for offshore legs with mission equipment. For passenger capacity, the TBM 960 is usually configured for about 4–6 passengers, the Avanti EVO commonly seats around 7–9, the Bell 525 is often configured around 12–16 seats, and the S‑92 typically carries roughly 12–19 passengers depending on layout and mission.
