Airbus Helicopters H135 vs Airbus Helicopters H145 vs Airbus Helicopters H175 vs Bell 429wlg Globalranger vs Bell 525 Relentless vs Leonardo Aw139 vs Leonardo Aw169

The Airbus H135 and Leonardo AW169 sit in the light twin category, while the Bell 429WLG is also a light twin positioned for similar EMS/corporate missions. The Airbus H145 is a larger light/intermediate twin, bridging into higher useful load and cabin volume. Moving up, the Leonardo AW139 and Airbus H175 are medium twins aimed at offshore, SAR, and high-capacity transport, and the Bell 525 Relentless is a “super-medium” twin optimized for longer-range offshore and higher cruise efficiency. In typical configurations, the H135 and Bell 429WLG generally carry about 5–7 passengers (plus crew), and the AW169 about 6–8. The H145 commonly carries around 8–10. The AW139 and H175 more often seat roughly 12–16 depending on layout, while the Bell 525 is typically in the mid-teens as well, with executive layouts trading seats for comfort. Range broadly steps up with size: H135/429WLG are shortest, AW169 and H145 are mid-range, AW139 and H175 are longer-range mediums, and the Bell 525 is usually the longest-range option in this set.
