When operated by the battery, how many VDC does the power supply system provide to the airborne electrical system?

Explanation:
When the system is operating from the battery, it provides a stable 24 V DC to the airborne electrical system. This voltage level is standard for many aircraft power setups because it delivers enough electrical power for avionics and controls while keeping wiring, components, and insulation within practical limits. The other voltages listed are not the battery-powered level in this configuration, which is why 24 V DC is the correct answer.
