What is the primary function of landing lights in aviation?

The primary function of landing lights in aviation is to provide visual assistance during landing. When an aircraft is approaching for a landing, these lights enhance visibility for both the pilots and those on the ground. They help illuminate the runway and enhance the aircraft's presence, especially in conditions of low visibility, such as at night or in poor weather. This visual assistance is crucial for ensuring a safe and precise landing, allowing pilots to better judge their altitude and distance from the runway.

While illuminating runways for night operations is a critical aspect of aviation safety, landing lights are specifically designed to enhance the landing phase for pilots more directly rather than simply illuminating the environment. Other functions, like providing guidance during takeoff or warning vehicles of aircraft movement, are not the primary roles of landing lights. Their main purpose is strictly related to aiding in the visual landing process.
