Leonardo Aw109 Grand New vs Leonardo Sh09 vs Robinson Helicopters R44 Raven Ii

The Leonardo AW109 GrandNew is a light twin‑engine helicopter in the “light intermediate” class, typically used for corporate, EMS, and utility missions. It generally offers the longest range of the three (often roughly in the 400–500+ nautical mile class depending on fit and reserves) and usually seats 6–7 passengers in a typical executive layout (with two pilots possible). The Robinson R44 Raven II is a light single‑engine piston helicopter aimed at private, training, and light utility use. It has the shortest typical range of this group (commonly around the 300–350 nautical mile class) and seats up to 3 passengers plus 1 pilot. The “Leonardo SH09” is not a currently marketed Leonardo helicopter model designation, so a direct, reliable comparison on range and capacity cannot be provided without clarification. If you mean the Swiss Helicopter (now Kopter) SH09, it is a light single‑engine turbine concept/aircraft positioned between the R44 and AW109 in capability, generally targeting around 6–8 seats and mid‑400 nautical mile class range depending on final configuration.
