Airbus Helicopters H175 vs Bell 429 Globalranger vs Leonardo Aw139 vs Sikorsky S 76d

All four are twin‑engine, IFR-capable helicopters, but they sit in slightly different size classes. The Airbus Helicopters H175 and Leonardo AW139 are typically grouped in the super‑medium category: they offer the highest passenger capacity of this set, commonly configured around 12–16 seats depending on layout, and they also tend to deliver the longest practical range, generally in the 400–600+ nautical mile class with typical reserves and mission equipment. The Sikorsky S‑76D is a medium helicopter optimized for speed and executive/offshore missions; it usually carries fewer passengers than H175/AW139, often around 8–12, with a range that is competitive but commonly a bit lower than the largest super‑medium configurations. The Bell 429 GlobalRanger is a light twin; it is the smallest here, usually configured for about 6–8 passengers, and it typically has the shortest range of the group, often roughly in the 300–400 nautical mile class depending on payload and fuel options. Actual figures vary by cabin layout, fuel tanking, and mission kit.
