During fueling operations, what should be the status of all electronics on the aircraft?

The correct approach during fueling operations is for all electronics on the aircraft to remain secure and unaltered. This is crucial because maintaining the integrity of the aircraft's electronic systems ensures safe fueling operations. If the electronics are tampered with, adjusted, or powered on during fueling, there could be potential for sparks or unintentional signals that might ignite fuel vapors. Keeping the systems secure and unaltered minimizes risks associated with electrical discharge that could compromise safety and lead to accidents.

Maintaining a secure state helps ensure that all systems function as intended and that any safety protocols associated with those electronic systems are not inadvertently bypassed or compromised during the critical fueling phase. This practice is in accordance with standard safety protocols for aviation fueling operations, aimed at preventing accidents and ensuring the safety of personnel and equipment.
