What does the annunciator signal indicate regarding fuel probe issues?

The annunciator signal indicating fuel probe issues serves as an alert that the fuel probe has failed. The purpose of the annunciator system is to provide real-time feedback about the operational status of various components, including fuel probes, which monitor fuel levels. When a fuel probe fails, it can no longer accurately measure and report the fuel level. The alert signals that there is a malfunction that could compromise the assessment of fuel amounts, which is crucial for safe operation and management of fuel resources.

Understanding this is essential because it highlights the need for immediate attention to repair or replace the failed probe, ensuring the continued safe and efficient operation of the system reliant on accurate fuel measurement.
