If a fuel imbalance greater than 3300 pounds is detected, what indicates the highest fuel level?

When a fuel imbalance greater than 3300 pounds is detected, the indication that highlights the highest fuel level is represented by a pulse green signal. This visual alert informs the pilots that one of the fuel tanks has significantly more fuel than the others, which is crucial for maintaining balance and performance during flight.

The green pulsing indicates a normal alert status related to fuel levels and is usually accompanied by a specific light on the fuel display, making it clear for pilots to address the situation. Monitoring and responding to fuel imbalances is essential for safety, as a greater imbalance could affect the aircraft's stability and control.

In contrast, other signals like steady red or pulse amber typically indicate system malfunctions or warnings that require immediate attention but do not specifically denote the highest fuel level. Steady red, for instance, may alert the crew to critical issues that need correction, whereas pulse amber generally signifies caution regarding various operational data, but not necessarily the context of fuel levels. Understanding these indicators is key for effective fuel management during flight operations.
