Airbus Helicopters H155 vs Bell 412epi vs Leonardo Aw139

All three are twin‑engine, IFR-capable utility helicopters, but they sit in different size and mission bands. The Airbus Helicopters H155 is a medium twin optimized for VIP/EMS and offshore shuttle work; it generally offers the longest reach in this group, with a typical range in the roughly 450–500+ nautical mile class depending on configuration. Passenger capacity is usually set up around 12 seats (or fewer for VIP/medical layouts). The Bell 412EPi is a medium utility twin derived from the 412 line, strongly oriented to public service, SAR, and general utility operations. Its range is typically shorter than the H155 and AW139, commonly around the mid‑300 nautical mile class, and it is often configured for about 10–13 passengers depending on interior and mission equipment. The Leonardo AW139 is a “super‑medium” twin, larger and higher performing than the other two, widely used for offshore transport, SAR, and corporate shuttle. Its range is generally in the high‑400 nautical mile class (config dependent), and passenger capacity is commonly around 12–15 seats.
