Question 1 of 27070

On runway approach, an ILS Localizer shows:

🔍 Key Concepts

• ILS (Instrument Landing System) localizer – what part of the approach it helps with • Difference between lateral guidance (left/right) and vertical guidance (up/down) • What instrument/system normally helps with glide path (vertical) vs. centerline (horizontal)

💭 Think About

• Ask yourself: Does the localizer tell you if you are left/right of the runway centerline, or high/low on the glide path? • Which ILS component is associated with vertical guidance (glide slope), and which with horizontal guidance? • Do localizers have anything to do with aircraft speed, or only position relative to the runway alignment?

✅ Before You Answer

• Confirm which ILS component gives lateral (left/right) guidance to line up with the runway. • Confirm which ILS component gives vertical (up/down) guidance on the glide path – this is NOT the localizer. • Check whether any ILS component directly measures ground speed or wind speed – and eliminate options that depend on speed rather than position.
