Complex airplane
![](../I/m/Mooney.m20j.g-muni.arp.jpg)
A complex airplane is defined by the United States, Federal Aviation Administration as an aircraft that has all of the following:
- A retractable landing gear (land aircraft only; a seaplane is not required to have this)
- A controllable-pitch propeller (which includes constant-speed propellers)
- Movable or adjustable flaps.
In the U.S., 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).
