A '''complex airplane''' is defined by the United States Federal Aviation Administration as an aircraft that has all of the following:<ref>{{Cite web |title=Multi Engine Rating - Definition, Privileges, & Requirements / ATP Flight School |url=https://atpflightschool.com/become-a-pilot/flight-training/multi-engine-rating.html |access-date=2023-12-04 |website=atpflightschool.com}}</ref>

*Retractable landing gear (land aircraft only; a seaplane is not required to have this). *A controllable-pitch propeller (which includes airplanes with constant-speed propellers and airplanes with FADEC which controls both the engine and propeller; turbojet and turbofan airplanes, except very rare mixed-propulsion airplanes, are not considered complex). *Movable or adjustable flaps.

The current FAA definitions of "complex airplane" are found in the Airplane Flying Handbook FAA-H-8083-3C Chapter 12 and in FAA Order 8900.2C.

In the US, students generally train for their first pilot certificate in an aircraft with fixed landing gear and a fixed-pitch propeller. It may or may not be equipped with flaps.

Before or after earning the private pilot certificate (PPL) (usually after), a pilot can be trained in complex aircraft operation by a flight instructor. When the pilot has demonstrated proficiency in complex aircraft, the flight instructor endorses the pilot's logbook and the pilot is said to have a "complex endorsement".

As of April 24, 2018 the FAA requires a commercial pilot applicant and CFI applicant to have experience in a complex aircraft; however, the practical test may be taken in a non-complex aircraft for the commercial pilot certificate (CPL) and the flight instructor certificate (CFI).
