(Refer to FAA-CT-8080-3F, Figures 61.) Determine your position relative to the glide slope and localizer course.

FAA Figure 61CDI indicatorFAA-CT-8080-3F · Instrument Rating supplement
How to read it: The vertical needle is the localizer, the horizontal needle the glide slope. Fly toward the needle: needle left = course is to your left; needle up = you are below the glide slope.
A

Below the glide slope and right of the localizer course.

B

Above the glide slope and left of the localizer course.

C

Above the glide slope and right of the localizer course.✓ Correct Answer

Explanation

Figure 61 shows a localizer frequency (109.9) with the vertical localizer needle deflected left of center and the horizontal glideslope needle below center. ILS needles point toward the course: the course is to the left, so the aircraft is right of the localizer, and the glideslope is below, so the aircraft is above the glide slope (IFH Ch. 9).
