Bell 525 Relentless vs Leonardo Aw189 vs Pilatus Pc 24 vs Sikorsky S 92

The Bell 525 Relentless and Leonardo AW189 are modern super‑medium helicopters, while the Sikorsky S‑92 is a larger heavy helicopter, and the Pilatus PC‑24 is a twin‑engine light business jet rather than a rotorcraft. In range terms, the PC‑24 typically offers the longest reach, commonly around 2,000 nautical miles class depending on payload and reserves, making it the best fit for longer point‑to‑point trips between runways. The helicopters generally trade range for vertical lift and offshore/remote access: the Bell 525 and AW189 are broadly similar, often in the roughly 450–500 nautical mile class in typical configurations, while the heavier S‑92 is commonly in a similar or slightly higher bracket depending on tanks and mission fit. For passenger capacity, the PC‑24 is usually configured for about 6–10 passengers. The AW189 and Bell 525 typically seat around 12–16 in high‑density layouts, with fewer in VIP. The S‑92 usually carries the most, commonly about 16–19, and is widely used where higher lift and cabin volume are priorities.
