Visual approach slope indicator (VASI). A visual aid of lights arranged to provide descent guidance information during the approach to the runway. A pilot on the correct glide slope will see red lights over white lights.

Visual approach slope indicator (VASI) - A visual aid to final approach to the runway threshold, consisting of two wing bars of lights on either side of the runway.

Visual Approach Slope Indicator (VASl): An airport lighting facility that provides vertical visual guidance to aircraft during approach and landing, by radiating a directional pattern of high intensity red and white focused light beams.

Visual Approach Slope Indicator (VASI)
A pair of lights to the side of the runway that tells the pilot that the plane is on a safe and reasonable descent to the runway. Red lights over white is the right thing to see.

VASI (visual approach slope indicator
Have two for G.A. aircraft or three bars for 747 types.
"Red over White, you're all right."
Three bar VASIs will have two red over white for G.A. aircraft.

VASIS - visual approach slope indicator system. A coloured light system providing
