During a "Electrical Failure," what is the initial action to take?

In the event of an "Electrical Failure," the initial action of switching to backup power sources is critical as it serves to immediately restore essential electrical functions necessary for safe flight operations. Backup power sources are designed to provide temporary power for critical systems, allowing the pilot to maintain control and access essential instruments. This step is crucial because it helps assess the overall situation and stabilize the aircraft's systems.

Attempting to reset the electrical systems may not be effective and could consume valuable time or resources that could otherwise be used for more critical actions. Notifying ground control of the situation is important but comes after ensuring the aircraft is stable and manageable. Preparing for an emergency landing could be necessary later in the sequence of actions if the situation does not improve, but the priority is to restore power to critical systems first.
