What should be done if a Fault Indicator Light is illuminated?

When a Fault Indicator Light is illuminated on an F/A-18 E/F aircraft, referring to the troubleshooting procedures and reporting the issue is the appropriate step to take. This action ensures that the fault is properly diagnosed according to established protocols, which is critical for maintaining safety and operational integrity.

The troubleshooting procedures provide systematic guidance on how to assess and handle the fault indicated by the light. These steps may include checking specific systems, interpreting diagnostic codes, and identifying potential causes of the fault. Reporting the situation is equally important, as it alerts maintenance personnel and allows for proper tracking and resolution of the problem.

This process underscores the principle that safety and thoroughness take precedence over operational expedience. By adhering to the proper procedure, the aircraft's airworthiness can be assured before further operations.

In contrast, options that suggest ignoring the indicator or resetting the system without assessment could lead to undetected issues, potentially resulting in more serious problems during flight operations. A visual inspection alone, while useful, may not provide the comprehensive analysis needed, and merely monitoring the system does not resolve the underlying fault.
