Under what condition do the Fuel Transfer Pumps automatically energize?

The correct answer is based on the operational design of the Fuel Transfer Pumps, which are engineered to activate under specific conditions related to the aircraft's power system. Fuel Transfer Pumps are designed to automatically energize when either of the engine generators is online, as this ensures that there is sufficient electrical power available to operate the pumps effectively.

In aircraft systems, when the generators are active, they provide the necessary energy to support various critical functions, including the fuel transfer mechanisms. This design ensures that fuel can be moved effectively between the tanks to maintain optimal performance and balance during flight.

Other conditions listed do not trigger the activation of the Fuel Transfer Pumps automatically, as they are either related to manual controls or conditions that do not directly correlate with the pump's operational requirements. Understanding the interdependence between the electrical systems and fuel management is essential for safe and efficient aircraft operations.
