What happens when the blue pump is activated?

When the blue pump is activated, it pressurizes the blue hydraulic system. This system is one of the three hydraulic systems found in the A320, which are used to provide the necessary pressure for various aircraft operations. The blue pump is specifically designed to supply additional hydraulic pressure to assist in tasks such as landing gear operation, flight control movements, and system redundancy. The activation of the blue pump enhances the reliability and performance of the hydraulic system by ensuring that there is adequate fluid pressure available when needed. The other options refer to actions related to different hydraulic systems or functionalities that do not occur when the blue pump is activated. Understanding the role of the blue pump allows for better insight into the overall hydraulic system management within the A320.
