Airbus Helicopters H225 vs Bell 525 Relentless vs Pilatus Pc 24 vs Sikorsky S 92

The Airbus H225 and Sikorsky S-92 are large twin‑engine helicopters primarily used for offshore energy, search and rescue, and VIP transport. Both typically carry around 18–19 passengers in transport layouts and offer medium-to-long helicopter range; the H225 is generally cited with a slightly longer typical range, while the S‑92 is often favored for rugged offshore operations and widespread fleet support. The Bell 525 Relentless is a newer-generation super‑medium twin helicopter positioned between these two classes: it targets similar missions with modern avionics and efficiency, usually seating in the mid‑teens to high‑teens depending on configuration, and offers competitive range for offshore legs, though it is generally considered below the largest “heavy” helicopters in cabin volume. The Pilatus PC‑24 is not a helicopter but a twin‑engine light jet, so it competes in a different category: it cruises much faster and typically flies far longer distances (roughly in the 2,000‑nautical‑mile class) with about 6–10 passengers in common executive layouts, trading vertical lift for speed, altitude, and runway-based access.
