Pedal-powered aircraft are human-powered flying machines that use pedaling as the primary means of propulsion. These aircraft typically feature lightweight designs and are equipped with large wings to generate lift. The pilot pedals to turn a propeller, which propels the aircraft forward, allowing it to take off and fly. These innovative vehicles often serve as a demonstration of human ingenuity and sustainability in aviation. They are part of a broader category of human-powered vehicles and are sometimes used in competitions, such as the Gossamer Albatross, which famously crossed the English Channel in 1979.
