The FAA has defined light-sport aircraft as simple-to-operate, easy-to-fly aircraft that, since initial certification, has continued to meet the following performance definition:

In addition to fixed-wing airplanes as pictured, light-sport aircraft also include powered parachutes, weight-shift control aircraft, balloons, airships, gliders and gyroplanes.
Any aircraft that meets the definition of a light-sport aircraft as called out in 14 CFR Part 1.1 is eligible to be operated by a sport pilot. These aircraft can be certificated in any category, such as standard, experimental amateur-built, experimental exhibition, experimental light sport aircraft (E-LSA), or special light sport aircraft (S-LSA).
