What does PAPI stand for?

• A. Precision Approach Patch Indicator
• B. Precision Approach Path Indicator
• C. Precision Approach Point Indicator
• D. Precision Approach Position Indicator

Answer: (A)

PAPI is a visual glide-slope aid that helps you stay on the correct descent path during approach. The acronym stands for Precision Approach Path Indicator. It uses four lights in a row that show red or white to communicate your vertical position relative to the desired glide path. The goal is to see four white lights, which indicates you’re on the intended approach path. Red lights mean you’re below the glide path, and a mix of colors signals deviation so you can adjust your pitch to rejoin the path. This system is a quick, at-a-glance cue used near the runway to ensure a safe, stable approach.
