The MLS approach is thought of as a localizer approach system and is not aligned with the runway centerline.
What is runway centerline?
It is a part of the airport lighting system that helps aeroplanes navigate across the taxiways at night or in bad weather when it is difficult to see the runway clearly. The edge lighting, which consists of white lights on the both edges of the runway, marks the boundaries of the runway while the centerline lights on the runway indicate where the runways are in the middle, allowing the pilot to navigate safely. At 3,000 feet from of the end of the runway, all centerline lights in the runway stay white. The centerline lighting system just on runway typically has a white colour at the approaching the runway's end and transitions to alternating white or red lights throughout its length.
