Here is the FAA's complex airplane definition:
A retractable gear (not necessary for a seaplane).
In-flight adjustable flaps; and.
A controllable pitch propeller.
How is this airplane defined under EASA and what is required to fly it? A pilot with EASA PPL is able to act as a PIC with retractable gear and flaps; or flaps and controllable pitch. Can he fly an airplane that has all three elements without any additional ratings or endorsements? Or are there any other requirements to fly this type of airplanes?
