What does a Fuel aux transfer failure notification indicate?

A Fuel aux transfer failure notification indicates that the system has detected an issue with transferring fuel from auxiliary tanks to the main tanks or ensuring that auxiliary fuel systems are functioning as intended. This situation can trigger the SPDS (Smart Power Distribution System) to enter failsafe mode. In failsafe mode, the system will implement safety protocols that may limit normal operations to prevent potential malfunctions or hazards associated with fuel transfer issues.

Recognizing a fuel aux transfer failure is crucial because it allows operators to take corrective actions and ensures the aircraft’s fuel system remains safe and operational. Understanding this concept is essential for maintaining flight safety and ensures that the crew can effectively manage fuel resources during a flight.
