Airbus Helicopters H155 vs Airbus Helicopters H175 vs Bell 429wlg Globalranger vs Bell 525 Relentless
The Airbus Helicopters H155 and Bell 429WLG GlobalRanger sit in the light-to-intermediate twin category, typically used for corporate, EMS, and utility work. Both generally carry around 6–8 passengers in a standard configuration (depending on interior and mission kit), with the H155 often positioned as a more premium, cabin-focused option. In range terms, they are usually in a similar “regional” class, commonly on the order of roughly 500–650 km (about 270–350 nm) depending on fuel fit, reserves, and payload. The Airbus H175 moves into the super-medium twin category, aimed at offshore, SAR, and higher-capacity transport. It typically offers a larger cabin and higher passenger capacity, commonly around 12–16 passengers in transport layouts, and a longer practical range than the H155/429 class, often roughly 650–850 km (about 350–460 nm) depending on configuration. The Bell 525 Relentless is also a super-medium twin, competing for offshore and long-range missions. It generally targets similar or greater passenger capacity than the H175 and comparable or longer range, commonly cited around 900–1,000+ km (about 500+ nm) depending on configuration and reserves.
