Bell 525 Relentless vs Piaggio Avanti Evo vs Pilatus Pc 24 vs Sikorsky S 92
The Bell 525 Relentless and Sikorsky S-92 are twin‑engine helicopters, while the Piaggio Avanti EVO and Pilatus PC‑24 are fixed‑wing turboprops and a light business jet, respectively. In range, the PC‑24 typically leads this group, offering roughly 2,000 nautical miles depending on load and reserves, making it best suited to longer point‑to‑point missions. The Avanti EVO generally sits behind it at about 1,500–1,800 nautical miles, optimized for efficient regional trips. The Bell 525 is a long‑range helicopter, commonly around 500–600 nautical miles, while the larger S‑92 is in a similar band, often roughly 500–600 nautical miles, with offshore configurations affecting endurance. For passenger capacity, the Avanti EVO is usually arranged for about 7–9 passengers, and the PC‑24 commonly seats about 6–10 in executive layouts (more in commuter/utility configurations). The Bell 525 typically carries around 12–16, and the S‑92 is the people‑mover of the group, often configured for roughly 19 passengers (or more seats in high‑density layouts).
