Powered Parachutes (PPCs) and Powered Paragliders (PPG) are just what you think: parafoil-type wings with a gas engine or electric motor to provide forward propulsion.
In the case of a PPC, the engine is usually mounted to a frame with wheels and a seat (non-ultralight two-seaters exist in the Light Sport category as well), while a PPG takes an even simpler approach – the engine is worn in a harness on the pilot’s back.
PPCs and PPGs represent some of the most inexpensive and accessible types of flying available.
