What is the indicated position at the outer marker if you are 1,550 feet to the left and 210 feet below the glide slope?

To determine the indicated position at the outer marker when you are 1,550 feet to the left and 210 feet below the glide slope, it's essential to understand the relationship between your aircraft's position relative to the glide slope and localizer.

Being 1,550 feet to the left of the localizer centerline means that your aircraft is not aligned with the centerline where you ideally should be for a proper approach to the runway. The term "left of the localizer centerline" indicates that your aircraft is offset to the left, which aligns directly with the correct answer indicating your position.

Additionally, being 210 feet below the glide slope suggests that you are not on the ideal vertical flight path to the runway, reinforcing the idea that your aircraft's position is outside of the intended approach profile. However, this vertical position primarily relates to the glide slope, while your lateral deviation is what confirms your positional status concerning the localizer.

The correct answer emphasizes that your aircraft is indeed left of the localizer centerline, clearly indicating your lateral offset in that specific orientation. This understanding is crucial for making necessary adjustments to re-align with the approach path.
