Airbus Helicopters H175 vs Bombardier Global 7500 vs Gulfstream G700 vs Leonardo Aw139 vs Leonardo Aw189 vs Sikorsky S 76d

The Airbus Helicopters H175, Leonardo AW139, Leonardo AW189, and Sikorsky S-76D are medium twin‑engine helicopters optimized for vertical lift missions, while the Bombardier Global 7500 and Gulfstream G700 are ultra‑long‑range business jets designed for high‑speed intercontinental travel. In range terms, the Global 7500 and G700 lead by a wide margin at roughly 7,000–7,700 nautical miles, enabling nonstop city pairs across oceans. The helicopters operate on far shorter legs: the AW189 and H175 are typically around 450–500 nautical miles, the AW139 roughly 500–600 nautical miles, and the S‑76D about 400–450 nautical miles, depending heavily on payload and reserves. Passenger capacity also differs: the Global 7500 and G700 usually carry about 12–16 passengers in executive configurations (with higher certified maximums), emphasizing comfort and cabin volume. The helicopters generally seat fewer in offshore/executive layouts but can be configured more densely: S‑76D commonly around 8–12, H175 and AW139 often about 12–16, and AW189 up to roughly 16–19 in high‑density seating.
