Bell 412epi vs Leonardo Aw139 vs Leonardo Aw169 vs Leonardo Aw189 vs Leonardo Sh09 vs Md Helicopters Md 500e vs Md Helicopters Md 902 Exlplorer vs Sikorsky S 76d

The MD Helicopters MD 500E and MD 902 Explorer are light helicopters: the 500E is typically configured for about 4–5 passengers with relatively short range, while the MD 902 carries more (often around 6–7 passengers) and generally offers somewhat better practical range, with NOTAR reducing tail-rotor hazards. The Bell 412EPi sits in the medium, twin‑engine utility class, commonly carrying roughly 10–13 passengers with moderate range suited to EMS, offshore support, and general transport. The Leonardo AW139 is a larger medium twin, typically 12–15 passengers with longer range than the 412EPi, optimized for offshore and high-utilization missions. The Leonardo AW169 is a lighter medium twin, usually around 8–10 passengers with mid-range capability, positioned between light twins and the AW139. The Sikorsky S‑76D is a medium twin focused on executive/offshore roles, typically about 8–12 passengers with solid mid-to-long range. The Leonardo AW189 is a heavy medium/super‑medium helicopter, often 16–19 passengers with the longest range in this group for offshore missions. The Leonardo SH09 is a light single-engine design concept with limited passenger capacity and shorter range than the medium twins.
