Airbus Helicopters H145 vs Airbus Helicopters H155 vs Bell 429wlg Globalranger vs Bell 525 Relentless vs Leonardo Aw109 Grand New vs Leonardo Aw139 vs Leonardo Aw169 vs Leonardo Aw189

Airbus H145 and Leonardo AW109 Grand New sit in the light twin category, typically carrying about 6–8 passengers with roughly 300–400 nm class range; the H145 generally offers a roomier, more utility‑oriented cabin, while the AW109 emphasizes speed and executive transport. Bell 429WLG GlobalRanger is also a light twin, commonly 6–7 passengers with a similar ~300–400 nm range, positioned between H145 and AW109 in cabin/mission balance. Airbus H155 and Leonardo AW169 are in the light‑intermediate/intermediate class, usually seating about 8–10 passengers and reaching roughly 400–500+ nm, offering larger cabins and better IFR/mission endurance than light twins. Leonardo AW139 and Airbus H155 overlap in the medium segment, but the AW139 is a benchmark medium twin, commonly configured around 10–15 passengers with about 500–600+ nm range depending on tanks and reserves. Leonardo AW189 and Bell 525 Relentless are heavier, long‑range types, often around 16–19 passengers with ~600–800+ nm class range, aimed at offshore, SAR, and high‑utilization transport.
