Which statement is true about threshold lighting color designations as seen from the approach?

• A. False
• B. True
• C. Not specified
• D. Only during the day

Answer: (B)

From the approach, runway threshold lighting is standardized so you can interpret the lights reliably. Threshold lights are green to mark the threshold as you approach, signaling where the usable runway begins. If you looked at the threshold from the opposite direction, the same area would be interpreted as part of the far end and appear red to indicate the end of the usable runway. This color coding is a fixed convention, used both day and night, so the statement that threshold lighting color designations as seen from the approach are true is correct. The other options aren’t accurate because the system isn’t limited to daytime, and there is a defined standard rather than an unspecified status.
