Figure 136: Precision approach path indicator (PAPI)

2 FAA questions that refer to this figure

1. Question 1 · Instrument Rating

   (Refer to FAA-CT-8080-3F, Figure 136.) An 'on glidepath' indication is

   • A.8
   • B.10
   • C.11
   Show answer and explanation

   Correct: B. 10

   A four-light PAPI shows on glide path when the two outer lights are white and the two inner lights are red (AIM 2-1-2). In Figure 136, that is indication 10 (two white, two red). Indication 8 (four white) is well above the glide path, and 11 (one white, three red) is slightly below it.

2. Question 2 · Instrument Rating

   (Refer to FAA-CT-8080-3F, Figure 136.) As you emerge from the clouds during an instrument approach and make visual contact with the runway environment, you see PAPI lights corresponding to those depicted in illustration 12. You are

   • A.on the glidepath.
   • B.above the glidepath.
   • C.below the glidepath.
   Show answer and explanation

   Correct: C. below the glidepath.

   Illustration 12 in Figure 136 shows four red PAPI lights. AIM 2-1-2 says four red lights mean the aircraft is below the glide path; two white and two red is on the path, and more whites than reds means above it.
