Airbus Helicopters H145 vs Bell 525 Relentless vs Leonardo Aw169 vs Sikorsky S 76d

The Airbus Helicopters H145 and Leonardo AW169 sit in the light twin segment, typically configured for around six to nine passengers depending on interior and mission fit, and generally offer the shortest ranges of this group, suited to regional corporate, EMS, and utility missions. The Sikorsky S-76D is a medium twin commonly used for offshore and executive transport; it usually carries about eight to twelve passengers and provides more range than the H145/AW169 class, making it a frequent choice for longer legs and overwater operations. The Bell 525 Relentless is a larger “super-medium” twin aimed squarely at offshore and high-utilization commercial work; it generally supports the highest passenger capacity of the four (often in the mid-teens in transport layouts) and the longest range, positioning it for extended offshore routes and higher payload missions. Overall, capacity and range step up from H145/AW169, to S-76D, and then to the 525, with each moving from light, to medium, to super-medium capability.
