What color light will illuminate when the aircraft is directly over the MIDDLE marker?

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

Answer: (C)

When an aircraft is directly over the middle marker during an ILS (Instrument Landing System) approach, an amber light will illuminate. The middle marker is typically associated with the final approach fix, indicating the aircraft is a certain distance from the runway. The amber light signifies that the aircraft is at the middle marker, guiding pilots in their approach by confirming they are on the correct path to landing. Each marker on an ILS approach has a specific light color associated with it: the outer marker emits blue light, the middle marker emits amber light, and the inner marker emits white light. Understanding these visual signals is crucial for pilots as they navigate during landing approaches, ensuring they have appropriate situational awareness and are following the correct glide slope and flight path.
