PAPI with two white and two red indicates what glide path?

PAPI with two white and two red indicates what glide path?

• A. Too high
• B. Too low
• C. Glide path unstable
• D. Correct glide path

Answer: (D)

PAPI provides a visual cue of your vertical position relative to the glide path. The four lights work together to show whether you’re on, above, or below the intended descent angle. Seeing an equal mix of colors—two white and two red—means you’re on the correct glide path for a standard approach, usually about 3 degrees. If more lights appear white (three or four white), you’re high and should descend toward the path. If more lights appear red (three or four red), you’re low and should climb back toward the path. So two white and two red is the clear signal that you’re aligned with the glide path.
