São Paulo is widely recognized as the world’s helicopter capital, with the largest fleet of helicopters in any city, surpassing even New York and Tokyo. The city operates a unique, dedicated helicopter air traffic control system—the only one of its kind globally—managing 13 designated helicopter corridors at altitudes between 2,000 and 3,500 feet.
