Step-by-step explanation:
When encountering a FAULT light in an SEC pb (Spoilers/Elevators/Computers pushbutton), it indicates that there is a malfunction or anomaly detected in the aircraft's spoiler and elevator control system. This system is critical for controlling the aircraft's flight attitude and stabilizing its movements in the air. A fault light typically requires immediate attention from the pilot and may necessitate the implementation of a specific checklist to troubleshoot and resolve the issue. The accurate interpretation and response to such warnings are a fundamental aspect of aviation safety and proper aircraft operation.
