The purpose of a sport aircraft license is to allow flying to be more affordable and accessible to people who are not necessarily going to pursue a serious career or hobby in flying. The sport aircraft license was added by the FAA as a category in 2004, and it is easier and cheaper to obtain than a private pilot license, for example. The sport aircraft license goes hand-in-hand with the light sport aircraft category, which has specific regulations in place that distinguish it from heavier aircraft. Light sport planes are designed to be simpler to pilot, but there are a number of other light aircraft that fall under this category: hot air balloons, gyroplanes, powered parachutes, airships, etc. While not every instance of each of these types of aircraft is considered light, these are the only other types of aircraft eligible to be called light sport aircraft. Anyone with a higher certification, such as a private pilot's license or commercial license, is permitted to pilot light sport aircraft, even with an expired medical certificate, as long as they have a driver's license that demonstrates their good health.
