What is the main purpose of the taxiway at an airport?

The main purpose of the taxiway at an airport is to create a safe path for aircraft between the runway and the terminal. Taxiways facilitate the movement of aircraft on the ground, allowing them to safely travel to and from the runway and various airport facilities, including gates and maintenance areas. This is essential for organizing the flow of traffic at busy airports and preventing congestion that could lead to delays or accidents.

Taxiways are also designed to ensure that aircraft can move without interfering with takeoff or landing operations occurring on the runway. Effective taxiway design and usage enhance overall safety and operational efficiency at the airport, enabling aircraft to maneuver in a manner that supports the busy rhythm of airline operations. The other choices, while they may represent aspects of airport operations, do not capture the primary function of taxiways in supporting aircraft ground movement.
