Leonardo Aw109 Trekker vs Leonardo Aw139 vs Leonardo Aw169 vs Leonardo Sh09

The Leonardo AW109 Trekker is a light, twin‑engine helicopter typically used for short to medium missions such as EMS, utility, and VIP transport. It carries a relatively small cabin load, generally around six to seven passengers in a high‑density layout (less when configured for medical or VIP), and offers solid but shorter range than the larger Leonardo twins. The Leonardo AW169 sits in the intermediate/light‑medium class, with a larger cabin and higher payload than the AW109. It commonly accommodates roughly eight to ten passengers depending on configuration, and its range is generally in the medium bracket, longer than the AW109 while remaining below the biggest models. The Leonardo AW139 is a medium twin and the capacity leader of the group. It is often configured for about 12 to 15 passengers, supports heavier mission equipment, and typically provides the longest practical range and endurance among these four for offshore, SAR, and transport roles. The Leonardo SH09 (single‑engine light) targets cost‑efficient, short to medium operations. Passenger capacity is usually in the five to seven range, with range and payload generally below the twin‑engine AW109/AW169/AW139.
