Airbus Helicopters H225 vs Bell 525 Relentless vs Cessna 208b Grand Caravan Ex vs Sikorsky S 92

The Airbus H225 and Sikorsky S-92 are large, twin‑engine heavy helicopters typically used for offshore oil and gas, search and rescue, and government transport. Both sit in the same broad category, with the H225 generally offering long‑range offshore capability and a high passenger load in the “high‑teens to around twenty” class depending on layout, while the S-92 is similarly a heavy transport with comparable range and a roughly similar passenger class, often configured around 19 seats for offshore missions. The Bell 525 Relentless is a newer‑generation, twin‑engine “super‑medium” helicopter, smaller than the H225 and S-92, aimed at offshore and executive roles with strong range for its class and typical seating in the mid‑teens, though it can be configured higher depending on mission kit and regulations. The Cessna 208B Grand Caravan EX is not a helicopter but a single‑engine turboprop airplane. It generally cruises farther and faster per unit fuel than rotorcraft on point‑to‑point legs, but needs runways. Passenger capacity is typically around 9–14 depending on configuration and rules.
