Bell 525 Relentless vs Cessna 208b Grand Caravan Ex vs Leonardo Aw189 vs Sikorsky S 92

The Bell 525 Relentless, Leonardo AW189, and Sikorsky S-92 are all medium, twin‑engine transport helicopters aimed at offshore, corporate/VIP, and utility roles, while the Cessna 208B Grand Caravan EX is a single‑engine turboprop fixed‑wing utility aircraft optimized for short, unimproved strips and low operating cost. In range terms, the Grand Caravan EX typically offers the longest legs in this group for point‑to‑point flying, often around the 900–1,000+ nautical mile class depending on load and reserves, whereas the three helicopters generally sit in the mid‑range bracket, roughly on the order of 450–550 nautical miles with typical passenger loads (mission equipment, reserves, and offshore requirements can reduce this). For passenger capacity, the S‑92 is usually the highest‑capacity helicopter of the group, commonly configured around 19 passengers for offshore transport; the AW189 is typically up to about 16–19 depending on layout; and the Bell 525 is generally in a similar 16–19 seat class depending on certification and interior. The Grand Caravan EX commonly seats about 9–14 passengers depending on configuration.
