What are the two primary types of pilot certificates issued by the FAA?

The two primary types of pilot certificates issued by the FAA are based on the categories of aircraft that a pilot is qualified to operate, which include Airplane and Rotorcraft. An Airplane pilot certificate allows a pilot to operate fixed-wing aircraft, while a Rotorcraft certificate is required for those who wish to fly helicopters and other rotorcraft types. These distinctions reflect the different skills and training required to operate these aircraft safely.

The other options provided refer to specific aircraft types or pilot ratings rather than the overarching categories of pilot certificates. For instance, options that mention gliders, helicopters, or light sport refer to specific types of flight, rather than broadly categorizing the pilot certification structure defined by the FAA. While private and commercial are classifications of pilot certificates based on the level of privileges granted, they do not encompass the primary categories of aircraft like Airplane and Rotorcraft do.
