RCLS is the acronym for which runway lighting system?

• A. RS-Runway Centerline Light System
• B. Runway Centerline Lighting System
• C. Runway Control Lighting System
• D. Runway Centerline Lighting Sequence

Answer: (A)

Recognizing what RCLS stands for in runway lighting terminology is the key idea here. The Runway Centerline Lighting System provides lights laid out along the centerline of the runway to help pilots keep the aircraft aligned with the runway axis, especially in low visibility. This system is about guiding you along the center of the runway, not about the edges or about sequencing lights. The option that uses RS-Runway Centerline Light System is considered the best match because, in some manuals and training materials, the Runway Centerline Lighting/Light System is abbreviated in a way that aligns with that RS phrasing, and it refers to the same centerline guidance concept described by RCLS. The important point is that the centerline lighting system is the dedicated guidance along the runway’s centerline, not the edge lighting, control lighting, or any sequencing of lights. Other names like Runway Centerline Lighting System describe the same idea in plain terms, but the RS variant reflects the specific acronym form you’re being asked to identify. A Runway Control Lighting System would be a different concept related to controlling lighting rather than the centerline guidance, and a Lighting Sequence would describe how lights change over time rather than the system as a whole.
