How It Works: VASI Lights - Aero Corner
VASI (pronounced “VAZ-ee”) stands for Visual Approach Slope Indicator. It is a set of lights mounted next to the approach end of a runway that helps a pilot align themselves with the invisible vertical approach path. The runway centerline and the runway itself help the pilot align longitudinally, or left and right of center.
Visual approach slope indicator - Wikipedia
The visual approach slope indicator (VASI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during final approach. These lights may be visible from up to 8 kilometres (5.0 mi) during the day and up …
