What is the primary function of a runway?

The primary function of a runway is to serve as the designated area an aircraft uses for landing and take-off. Runways are specifically designed and constructed to withstand the high forces exerted on them during these critical phases of flight. The surface materials and dimensions of the runway are tailored to accommodate the weight and speed of various aircraft, ensuring safe operations. This vital function facilitates the movement of aircraft, allowing them to ascend into the sky or land safely back on the ground.

While pre-flight checks, passenger waiting areas, and baggage handling services are all important aspects of airport operations, they are not the fundamental purpose of a runway. The runway's role is strictly related to the aircraft's flight operations, making it essential for the overall efficiency and safety of air travel.
