Need Help with this question it is giving me a hard time
Anyone can taxi an aircraft, if you know how.
The only limitations would be those stipulated by the aircraft owner and/or insurance company who would want to set some minimum experience or training so that nothing gets damaged.
Some airports have their own regulations as to who is qualified to taxi an aircraft. These airport regulations might vary depending on the complexity and size of the aircraft.
Only qualified persons shall start and/or operate an Aircraft engine at the Airport and/or taxi an Aircraft on the Airport. Qualified persons include a pilot, an airframe and power plant mechanic, or a qualified technician licensed by the FAA and qualified to start or operate the engine(s) and/or taxi that particular type and class of Aircraft.
Depending on the jurisdiction, a radio licence might also be required if you need to use the radio.
Airports frequently have rules who could taxi the aircraft within they boundaries (normally pilot, student pilot or mechanic). This question contains more information.
Moving over ground between two points without intention of flying is not a flight.
