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

1. Red light signal

2. Amber light signal

3. Green light signal

4. White light signal

The correct answer is: Amber light signal

When interpreting a tri-color VASI (Visual Approach Slope Indicator), an above-glide slope indication is signified by an amber light signal. The tri-color VASI uses different colors to convey the aircraft's position in relation to the glide slope: - The green light indicates that the aircraft is on the correct glide slope. - The amber light means that the aircraft is too high and needs to descend to meet the proper glide slope. - The red light shows that the aircraft is too low and also requires adjustments to return to the proper glide path. Thus, an amber light indicates that the pilot should take action to descend and align with the glide slope for a safe approach. Understanding these color signals is crucial for pilots to ensure proper descent and landing procedures.
