Bell 525 Relentless vs Md Helicopters (mcdonnell Douglas) 902 Explorer vs Sikorsky S 92

The Bell 525 Relentless, MD Helicopters (McDonnell Douglas) 902 Explorer, and Sikorsky S-92 sit in different helicopter categories, so their capabilities diverge sharply. The MD 902 Explorer is a light twin, typically used for EMS, law enforcement, and short-range corporate or utility work; it generally carries around 7–8 passengers (depending on configuration) and offers comparatively modest range suited to regional missions. The Bell 525 is a modern super‑medium helicopter aimed at offshore energy, corporate/VIP, and high-utilization transport; it carries roughly 16 passengers in typical layouts and provides long range for extended overwater or point-to-point missions. The Sikorsky S‑92 is a larger heavy (often described as medium‑lift in some markets) transport helicopter optimized for offshore and SAR; it commonly seats about 19 passengers and is built for robust operations and longer-range missions, generally comparable to or greater than the 525 depending on payload and fuel configuration. In short, the 902 is the smallest and shortest-legged, the 525 is a long-range super‑medium with mid-teen seating, and the S‑92 is the largest with the highest passenger capacity and strong long-range offshore focus.
