Airbus Helicopters H135 vs Airbus Helicopters H145 vs Gulfstream G650er

The Airbus Helicopters H135 and H145 are light twin‑engine helicopters designed for short‑range missions, while the Gulfstream G650ER is an ultra‑long‑range business jet built for intercontinental travel. The H135 is typically used for training, EMS, and utility work; it generally carries about five to seven passengers depending on configuration and payload, with an operational range on the order of roughly 300 nautical miles. The H145 is a larger light/medium twin helicopter with more cabin volume and higher useful load; it commonly accommodates about seven to nine passengers (or more in specialized layouts) and offers a somewhat longer typical range, often around 350 to 400 nautical miles. In contrast, the G650ER operates in a different class entirely: it is a large‑cabin, high‑speed jet that usually seats around 11 to 18 passengers in executive configurations and can fly approximately 7,500 nautical miles, enabling nonstop routes such as New York to Hong Kong under favorable conditions.
