GLAM stands for which four ILS components?

• A. Glideslope, Localizer, Approach Lighting System, Marker Beacon
• B. Glideslope, Localizer, Altimeter, Marker Beacon
• C. Groundspeed, Localizer, Approach Lighting System, Marker Beacon
• D. Glideslope, Longitude, Approach Light System, Marker Beacon

Answer: (A)

GLAM is the four components that make up the Instrument Landing System on approach terrain: Glideslope, Localizer, Approach Lighting System, and Marker Beacon. The Localizer provides horizontal guidance to keep you centered on the runway, while the Glideslope gives vertical guidance to help you descend along the proper path. The Marker Beacon offers distinct position cues along the approach (outer, middle, and inner markers) to confirm your location and altitude relative to the runway. The Approach Lighting System enhances visibility during the final approach, helping you transition from instrument to visual cues in low visibility conditions. Choices that include Altimeter, Groundspeed, or Longitude aren’t part of the ILS components, which is why they don’t fit.
