What type of lighting aids in adverse visibility conditions?

Runway End Identifier Lights (REIL) serve a significant role in enhancing safety during adverse visibility conditions, such as fog, rain, or nighttime operations. These lights are typically installed at the ends of runways and provide visual cues to pilots about the location of the runway threshold. The bright, flashing lights assist in guiding aircraft during the approach and landing phases, helping ensure that they can safely identify the runway even in poor visibility.

The effective use of REIL contributes to reducing confusion and potential accidents, making them particularly important for pilots operating in situations where visibility is compromised. This functionality is critical in promoting safe landings and maintaining operational efficiency in adverse weather situations.

General aviation lighting, taxiway lights, and obstruction lights serve different purposes that do not specifically target the challenges presented by low visibility during landing phases, making them less effective in this particular context.
