Bell 525 Relentless vs Enstrom 480b vs Sikorsky S 92
The Bell 525 Relentless and Sikorsky S-92 are large, twin‑engine helicopters aimed at offshore, corporate, and utility missions, while the Enstrom 480B is a much smaller, single‑engine helicopter typically used for training, patrol, and light utility work. In range, the Enstrom 480B generally offers the shortest endurance and mission radius, suited to regional flights rather than long overwater legs. The Bell 525 is designed for longer-range, higher-speed operations than light singles and is commonly positioned as a modern offshore-capable aircraft. The Sikorsky S-92 is also optimized for offshore transport, with long-range capability and strong all-weather performance, often favored where payload and mission robustness matter as much as distance. Passenger capacity follows the same pattern: the Enstrom 480B is a small-cabin aircraft carrying only a handful of people, whereas the Bell 525 and S-92 are in the “transport” class, typically configured to carry around a dozen or more passengers depending on interior layout and mission equipment.
