Airbus Helicopters H155 vs Bell 429 Globalranger vs Leonardo Aw109 Grand New vs Leonardo Aw139 vs Leonardo Aw189

These aircraft span light to super‑medium categories with corresponding increases in cabin size and range. The Airbus Helicopters H155 sits in the light‑intermediate twin class, typically configured for about 12–13 passengers and offering medium range suited to corporate and utility missions. The Bell 429 GlobalRanger is a lighter twin than the H155, generally carrying about 6–7 passengers (up to around 8–9 in high‑density layouts) with shorter overall range than the H155. The Leonardo AW109 Grand New is a light twin focused on speed and executive transport, commonly seating about 6–7 passengers, and its range is broadly comparable to the Bell 429, varying notably with payload. Moving up, the Leonardo AW139 is a medium twin with a much larger cabin, typically seating around 12–15 passengers and delivering longer, more mission‑flexible range than the H155/429/AW109. At the top end here, the Leonardo AW189 is a super‑medium twin designed for offshore and SAR, usually accommodating roughly 16–19 passengers and offering the longest range of this group, especially in long‑range configurations.
