What is the primary function of taxiways?

The primary function of taxiways is to serve as designated roadways for aircraft movement on the airport's surface. Taxiways connect runways with other taxiways, terminals, and hangars, allowing aircraft to traverse the airport safely and efficiently without interfering with takeoff and landing operations. Properly designed taxiways enable aircraft to reach their gates or other areas of the airport while minimizing congestion and enhancing safety.

The other potential functions listed do not align with the primary purpose of taxiways. While waiting areas for aircraft and hangar access are important features of airport design, they are not the main role of taxiways. Runways are specifically constructed for takeoff and landing, making them unsuitable for the movement purposes served by taxiways. This distinction is crucial for airport operations and ensuring safe passage for all aircraft.
