Which statement correctly describes the approach lighting marker cones placed off the MOS?

Understanding how many marker cones and how far from the MOS they are placed helps ensure pilots get clear, consistent guidance during the final approach. The standard approach lighting off-MOS uses seven marker cones positioned two hundred feet from the MOS. This arrangement provides reliable lateral cues without crowding the area near the MOS, giving pilots a recognizable path cue early in the approach. Deviating from this—such as using more cones or placing them closer at one hundred feet—changes the standard cueing pattern and can reduce clarity or interfere with other lighting components, which is why the seven-cone, two-hundred-foot setup is the correct choice.
