Airbus Helicopters H155 vs Leonardo Aw109 Grand New vs Leonardo Aw139 vs Leonardo Sh09

The Airbus Helicopters H155 is a medium twin positioned for corporate and offshore missions, typically offering the longest legs among this group with a long-range fit and a cabin sized for roughly 8–12 passengers depending on layout. The Leonardo AW109 GrandNew sits in the light twin category, optimized for speed and VIP/EMS roles, with shorter overall range than the larger medium twins and a typical passenger load around 6–7 (often up to about 8 in high-density arrangements). The Leonardo AW139 is a medium twin aimed at offshore, SAR, and utility work; it generally provides longer range and higher payload than the AW109, and commonly carries about 12–15 passengers in transport configurations. The Leonardo SH09 is a light single intended primarily for training and light utility; it has the shortest range and lowest passenger capacity here, typically around 4–5 seats total (including the pilot), making it best suited to short-haul missions rather than multi-passenger transport.
