The Leonardo AW139 and Sikorsky S-76D sit in the medium twin category, typically used for offshore, EMS, and corporate transport; both offer solid range for regional missions and generally seat around 8–12 passengers depending on interior fit, with the AW139 often configured toward the higher end. The Leonardo AW189 is a larger heavy twin optimized for offshore work, with longer legs and more cabin volume than the AW139/S-76D class, commonly accommodating roughly 16–19 passengers in transport layouts. The Leonardo SH09 is a light single, aimed at utility and training roles; it offers shorter range than the twins and typically carries about 4–5 occupants. MD Helicopters’ MD 500E is a light single with modest range and usually 4–5 seats, favoring agility and low operating cost. The MD 902 Explorer is a light twin with more redundancy and a larger cabin than the 500E, generally seating about 6–8 with medium-range capability. The Robinson R66 is a light single positioned between the small trainers and larger utility aircraft, with moderate range and typically 4–5 seats.
