Marker beacons along the approach include Outer Marker, Middle Marker, and Inner Marker; which marker is encountered first?
Correct Answer:
Outer Marker.
Explanation:
Marker beacons on an ILS are arranged from farthest to closest to the runway to guide you through the final approach. The Outer Marker is placed farther from the threshold, followed by the Middle Marker, and then the Inner Marker near the runway. Because of this layout, you encounter the Outer Marker first as you descend the approach, then the Middle Marker, and finally the Inner Marker. The markers also have distinct colors and Morse identifiers (Outer Marker, Middle Marker, Inner Marker) to help you recognize which beacon you’re crossing. That sequencing is why the first marker you encounter on the approach is the Outer Marker.
