What is the primary function of runways at an airfield?

The primary function of runways at an airfield is takeoff and landing. Runways are specifically designed and constructed to provide a smooth and strong surface that allows aircraft to accelerate for takeoff and decelerate upon landing. The design of a runway takes into account factors such as length, width, and surface materials, which are crucial for safely accommodating various types of aircraft under different weather conditions.

While runways may be adjacent to other areas for aircraft parking, maintenance, or equipment storage, their essential purpose is to facilitate the movement of aircraft in and out of the airspace. This critical function ensures the safe operation of aviation activities and is the primary reason for their existence at an airfield.
