If all VASI lights appear red, what does it indicate?

Explanation:
VASI uses color to show whether you’re above or below the intended glidepath. Red means you’re below the glidepath, while white means you’re above it. If all the lights are red, you are well below the glidepath and should gently raise the nose to reduce descent and re-intercept the glide slope. As you ascend toward the path, the lights will transition toward white, and when you’re on the glidepath you should see white lights indicating proper alignment.
