During a load shed, which systems are prioritized?

• A. Entertainment systems
• B. Critical operations and safety-related systems
• C. Navigation only
• D. Non-essential avionics

Answer: (B)

During a load shed, the priority is to keep power available for systems essential to flying safely. The electrical system has limited capacity, so power must be allocated first to what keeps the aircraft controllable and safe: the critical operations and safety-related systems. This includes flight controls, essential flight instruments and displays, navigation and communication equipment needed to maintain situational awareness, and warning or alert systems that help the crew respond to abnormal conditions. Keeping these powered ensures the pilot can maintain control, monitor the aircraft’s status, and communicate as needed.

Nonessential items, such as entertainment systems, or non-critical avionics that don’t affect immediate flight safety, are shed to free up power. A navigation-only approach would leave out other crucial safety systems that also require power, so it’s not the best choice in a load-shed scenario.
