What happens when the hydraulic switches are set to AUTO?

When the hydraulic switches are set to AUTO, the system automatically manages the hydraulic pumps based on the position of the flaps. If the flaps are extended out of the 0 position, the pump is activated to provide the necessary hydraulic pressure for the operation of the flaps. This ensures that the flaps can operate effectively when commanded, allowing for proper aircraft performance during various phases of flight. The automatic function of these switches allows for a more responsive system, engaging the pump only when necessary to conserve energy and reduce unnecessary wear on the system.
