What term describes the ground movement of an airplane between locations?

The term that best describes the ground movement of an airplane between locations is "Taxi." This refers to the process where an aircraft moves on the ground, typically under its own power, to and from the runway, taxiways, and the terminal or ramp area. During taxiing, pilots follow air traffic control instructions to ensure safe and efficient movement on the ground.

In contrast, a taxiway refers to the specific paths designed for this ground movement, connecting runways with ramps and terminals. The ramp, or apron, is the area where aircraft are parked, loaded, or unloaded. An uncontrolled airport is a facility that does not have an active air traffic control tower, which does not pertain directly to the defined movement of the aircraft itself. Thus, "Taxi" is the most accurate term for this ground movement activity.
