What color indicator is associated with the inner marker beacon during a Category II approach?

The inner marker beacon during a Category II approach is indicated by a white color. This specific color signaling is part of the standardization in aviation to ensure pilots can quickly recognize and react to different markers indicating their position in relation to the runway and approach path.

In a Category II approach, the inner marker serves a critical purpose in enhancing situational awareness during low visibility conditions. The white light signifies that the aircraft is approaching the decision height, at which the pilot must be prepared to land or execute a missed approach if the runway environment is not clearly visible.

Understanding the significance of the white indicator helps pilots identify their location in the approach sequence accurately, ultimately improving safety during instrument approaches. The recognition of color coding is key in instrument flying, as it enables rapid understanding of navigational information in a high-tempo and often stressful operational environment.
