What happens to the affected surface when a loss of redundancy fault occurs?

When a loss of redundancy fault occurs, it is critical for the pilot and crew to be able to quickly identify which surfaces are affected for safety and operational readiness. In this context, the correct choice indicates that the affected surface is displayed in red. This color coding serves as a visual alert to signify that there is a serious issue that impacts the system’s reliability, making it crucial for the crew to take immediate notice and implement corrective action.

The use of red in aviation systems typically denotes a malfunction or condition that requires urgent attention. Maintaining a clear visual system not only facilitates rapid assessment during flight but also ensures that proper procedures can be followed in response to the fault. Therefore, recognizing that an affected surface will display in red reinforces the importance of vigilant monitoring of system statuses.
