(Refer to FAA-CT-8080-2H, Figure 47.) While on final approach to a runway equipped with a standard 2-bar VASI, the lights appear as shown by illustration D. This means that the aircraft is
- Aabove the glide path.
- Bbelow the glide path.
- Con the glide path.
Show answer and explanation
Correct answer: B. below the glide path.
Each VASI light unit shows white in the upper part of its beam and red in the lower part (AIM 2-1-2). On a 2-bar VASI, seeing red on both the near and far bars (illustration D in Figure 47: all six lights red) means the aircraft is below the glide path. Red over white is on the glide path, and white over white is above it.
