What occurs when the Cabin Master Switch is set to SHED position?

When the Cabin Master Switch is set to the SHED position, it performs the specific function of shedding non-essential electrical loads in the cabin. This operational mode is designed to prioritize power distribution during critical phases of flight, such as ascent or emergency situations, where conserving battery power is essential.

In the SHED position, while certain non-essential systems may be turned off to conserve energy, the system is designed to allow for recovery of some items once normal operating conditions are restored, or when the non-essential systems can be safely re-engaged. This selective management of electrical loads ensures that essential systems remain operational, enhancing safety and efficiency.

Understanding this function is crucial, especially when managing cabin power during various aircraft operations, as it contributes to maintaining essential services while effectively managing battery life.
