What should be done if you notice fluctuating fuel levels on the synoptic page?

If fluctuating fuel levels are observed on the synoptic page, the appropriate course of action involves continuing normal operations unless a caution appears. This approach is grounded in the understanding that fuel level fluctuations can be typical conditions under certain flight scenarios, especially in specific aircraft designs or under certain operational contexts.

The synoptic page serves as a monitoring tool for system status and can reflect momentary variations in fuel levels due to factors such as fuel sloshing or momentary sensor inaccuracies. As long as there are no accompanying warning or caution indications — which would suggest a more serious issue with the fuel system — it is generally safe to proceed with normal flight operations. This allows for the maintenance of routine procedures while remaining vigilant for any potential signs of malfunction that would require a more immediate and drastic response.

In contrast, actions such as manually adjusting fuel pumps or shutting down fuel systems may lead to unnecessary disruptions in operations and could compromise flight safety. Reporting to maintenance immediately may also be excessive if no caution is displayed, as this could lead to unnecessary ground time or maintenance interventions when the situation might resolve naturally. Hence, monitoring the situation while maintaining normal operations is typically the best approach in the absence of cautions.
