Leonardo Aw169 vs Leonardo Aw189 vs Robinson Helicopters R66 vs Sikorsky S 76d

The Leonardo AW169 and AW189 are medium twin‑engine helicopters, with the AW189 being the larger, heavier‑lift model. The AW169 typically carries around 8–10 passengers (depending on configuration) and offers a moderate range suited to regional shuttle, EMS, and utility missions. The AW189 is designed for higher passenger loads and offshore/longer missions, commonly seating about 16–19 passengers and generally providing longer range than the AW169. The Robinson R66 is a light, single‑engine helicopter aimed at cost‑efficient private, training, and light utility use. It carries up to 4 passengers (plus a pilot, for 5 total seats) and has a shorter range than the twin‑engine aircraft listed, reflecting its lighter category and mission profile. The Sikorsky S‑76D is a medium twin, often used for offshore transport and executive/VIP roles. It typically seats about 12 passengers and offers range broadly comparable to, or in some missions slightly exceeding, the AW169, while generally sitting below the AW189 for maximum passenger capacity and heavy offshore emphasis.
