Airbus Helicopters H145 vs Airbus Helicopters H175 vs Bell 412epi vs Leonardo Aw139 vs Sikorsky S 76d

All five are twin‑engine civil helicopters, but they span light to medium classes with different typical missions. The Airbus H145 is a light twin aimed at EMS, police, and utility work, offering roughly 350–400 nm of range and typically 8–10 passengers (about 1–2 pilots plus up to 9 in high‑density layouts). The Sikorsky S‑76D is also a light twin but optimized for corporate/offshore transport, with broadly similar range around 400 nm and usually 8–12 passengers depending on interior. Moving up, the Bell 412EPi is a medium twin utility helicopter emphasizing hot‑and‑high and lifting capability; it commonly carries about 10–13 passengers and reaches roughly 350–400 nm. The Leonardo AW139 is a fast, modern medium twin widely used offshore and for SAR, typically seating about 12–15 passengers with around 500–600 nm range. At the larger end here, the Airbus H175 is a super‑medium twin designed heavily around offshore and SAR, generally carrying about 16–18 passengers with range commonly around 550–650 nm. Actual figures vary with fuel, payload, and cabin configuration.
