Airbus Helicopters H155 vs Airbus Helicopters H160 vs Leonardo Aw169 vs Sikorsky S 76d

All four are twin‑engine, IFR‑capable medium helicopters commonly used for offshore transport, EMS, and VIP missions, but they sit in slightly different size and performance bands. The Airbus H155 is a proven “medium” class aircraft with typical seating around 12 passengers (often configured lower for VIP) and a range generally in the 450–500 nm class depending on tanks and reserves. The newer Airbus H160 is a more modern medium twin emphasizing efficiency, comfort, and lower noise; it is usually marketed around 12 passengers with a broadly similar or slightly improved practical range versus the H155, commonly roughly 450–550 nm by configuration. The Leonardo AW169 is a lighter intermediate twin, typically accommodating about 8–10 passengers, with range commonly around 400–450 nm. The Sikorsky S‑76D is a classic medium twin favored for offshore and executive work; it typically carries about 12 passengers in transport layouts and offers range generally in the 400–500 nm bracket, varying with mission kit and fuel. Actual numbers depend heavily on interiors, auxiliary tanks, payload, and regulatory reserves.
