Airbus Helicopters H155 vs Airbus Helicopters H215 vs Bell 525 Relentless

Airbus Helicopters’ H155, H215, and Bell’s 525 Relentless sit in different parts of the civil/utility helicopter spectrum. The H155 is typically positioned as a medium, twin‑engine helicopter optimized for corporate and offshore passenger transport, with a comparatively modest range and a cabin sized for roughly a dozen passengers in high‑density layouts, often fewer in VIP configurations. The H215 is a heavier, twin‑engine “Super Puma” class aircraft aimed at utility and offshore lift, trading a larger airframe and higher payload capability for range that is generally in the medium-to-long bracket, and passenger capacity commonly around the high‑teens to low‑20s depending on seating and mission kit. The Bell 525 Relentless is a modern “super‑medium” twin designed for offshore and executive missions, typically offering long-range capability competitive with its class and a spacious cabin that usually seats around the mid‑teens in airline-style layouts, with flexible configurations. Exact range and seating vary significantly with fuel options, reserves, cabin fit, and payload.
