Airbus Helicopters H145 vs Airbus Helicopters H175 vs Sikorsky S 76d

The Airbus Helicopters H145 is a light twin-engine helicopter suited to short-to-medium missions such as EMS, law enforcement, and utility work. It typically carries about 8 to 10 passengers in a transport configuration (or fewer with special mission equipment) and offers a generally shorter range than the larger two aircraft, roughly in the mid-hundreds of nautical miles depending on payload, fuel, and reserves. The Airbus Helicopters H175 is a super-medium class helicopter designed for offshore transport and longer-range, higher-payload operations. It usually accommodates around 16 passengers in an offshore seating layout and delivers the longest practical range of the three, commonly on the order of about 500 nautical miles class, again varying with configuration and conditions. The Sikorsky S-76D sits between them as a medium twin, widely used for offshore, corporate, and SAR roles. It typically carries about 12 passengers and offers a range generally comparable to, or slightly below, the H175 and above the H145, often in the roughly 400 nautical miles class depending on mission fit.
