O'Hare Airport Blue Stripe Practice Test

Runway edge lights are indeed white, serving a specific purpose in air traffic management. These lights define the edges of a runway, providing pilots with visual guidance during takeoff and landing, particularly in low visibility conditions. The uniformity in color helps standardize the experience for pilots, allowing for quick recognition of runway boundaries at various airports.

Runway edge lights are designed not only for safety but also for consistency across different locations, ensuring that pilots can rely on them regardless of their familiarity with a specific airport. In contrast to other types of lights, such as approach lights or runway threshold lights that may use different colors for specific signaling, the use of white lights on runway edges assists in avoiding confusion and enhances overall operational safety.
