An on glide slope indication from a tri-color VASI is represented by what light signal?

Red light signal

Amber light signal

Blue light signal

A green light signal

An on glide slope indication from a tri-color VASI (Visual Approach Slope Indicator) is represented by a green light signal. The purpose of the VASI is to provide visual guidance to pilots during the approach phase of landing by indicating whether they are on the correct glide slope, above it, or below it.

When a pilot sees a green light from the VASI, it means they are correctly aligned with the optimal approach angle for landing. This helps ensure a safe descent without being either too high or too low, which are critical factors in achieving a successful landing. The green light is an essential indicator for pilots, as it communicates that they are in the correct position to land safely.

In contrast, other colors may indicate different states, such as being too low or too high, thus emphasizing the importance of recognizing the green signal for proper glide slope alignment.
