Which item is automatically shed when the GEN annunciator illuminates?

When the GEN annunciator illuminates, indicating a failure in the aircraft's generator system, the air conditioning system is automatically shed. This is a critical safety feature designed to conserve battery power and ensure that essential systems remain operational when electrical supply is compromised.

By shutting down the air conditioning, the aircraft can redirect available electrical power to maintain vital instruments and systems, such as avionics and essential lighting, enabling continued control and navigation of the aircraft. The landing gear, navigation lights, and wing flaps, while important, are not automatically shed in response to a generator failure. Protection of the air conditioning system in this scenario reflects an understanding of prioritizing power allocation to maintain flight safety.
