How many passengers is a sport pilot allowed to carry on board?

A sport pilot is allowed to carry only one passenger on board. This restriction arises from the definition and limitations established for sport pilots under the Federal Aviation Administration (FAA) regulations. The sport pilot certificate is designed for pilots flying light-sport aircraft, which are generally less complex and have fewer operational requirements than full private pilot or commercial pilot licenses.

The single passenger limitation emphasizes safety and the relatively less experience of sport pilots, ensuring that they can manage the aircraft and passengers effectively in controlled circumstances. This regulation helps maintain a careful balance between the recreational nature of sport aviation and the safety of operations in the airspace.

The other options suggest allowing more passengers than is permitted and do not align with the regulations governing sport pilot certification and operation of light-sport aircraft. This limitation supports the safety objectives of the sport pilot rules while promoting a manageable flying experience.
