The visual components of an Instrument Landing System (ILS) primarily consist of the Glide Slope and Localizer, which provide crucial guidance to pilots during the final approach phase of landing. The Glide Slope gives vertical guidance, helping to maintain the appropriate descent path, while the Localizer provides horizontal guidance to ensure the aircraft is aligned with the centerline of the runway.

While components like DME and Compass Locators might play a role in navigation and situational awareness, they are not specifically part of the ILS system. Instead, the markers, like the outer and inner markers, could be tied to ILS but do not constitute the visual components essential for the approach itself.

Understanding these components is vital for pilots to ensure safe and efficient instrument approaches, as the Glide Slope and Localizer work together to guide the aircraft precisely to the runway.
