Bell 412epi vs Leonardo Aw139 vs Leonardo Aw189 vs Leonardo Sh09

In category terms, the Bell 412EPi is a medium twin best aligned with utility and short‑to‑medium regional missions, while the Leonardo AW139 is a larger medium twin optimized for faster, longer point‑to‑point transport and offshore/EMS roles. The Leonardo AW189 sits a step up as a super‑medium, emphasizing higher payload, longer endurance, and offshore capability. The Leonardo “SH09” is best understood as a light single‑engine helicopter concept rather than a medium twin; in typical market positioning it targets lower‑cost short‑range missions such as training, surveillance, and light utility work. For range, the AW139 and AW189 generally offer longer legs than the 412EPi, with the AW189 typically leading due to greater fuel and payload margins, and the SH09/light single class usually trailing the medium twins. For passenger capacity, the 412EPi commonly carries around the low‑teens in high‑density seating, the AW139 similarly spans roughly the low‑ to mid‑teens depending on interior, and the AW189 typically supports the highest practical passenger loads in this group (often mid‑teens to high‑teens in transport layouts).
