Which color marker beacon light corresponds to the middle marker?

• A. Blue
• B. White
• C. Amber
• D. Green

Answer: (C)

Marker beacons on an ILS provide visual cues along the approach, with distinct colors for quick identification. The outer marker is shown by a blue light, the middle marker by an amber light, and the inner marker by a white light. The amber middle marker sits between the outer marker and the runway, signaling that you’re approaching the final portion of the approach and near the decision point. This color coding helps pilots recognize their position on the approach at a glance, reducing confusion during critical moments. So, the middle marker is indicated by the amber light.
