Final answer:
The BLUE ELEC PUMP on the HYD PANEL in AUTO mode will automatically operate in certain safety and redundancy scenarios, such as when the blue hydraulic pump pressure is low, there is loss of pressure in the green hydraulic circuit, during cargo door operations, or when the landing gear is not uplocked during flight.
Step-by-step explanation:
In the context of aviation and aerodynamics, the HYD PANEL, or Hydraulic Panel, is a crucial component in the aircraft's hydraulic system. Specifically, regarding the AUTO mode operation of the BLUE ELEC PUMP (Blue Electric Pump), this is a safety and redundancy feature found in aircraft such as the Airbus A320 family. The Blue Electric Pump will automatically operate under several conditions:
- When the engine-driven blue hydraulic pump pressure is low.
- If there is a loss of pressure in the green hydraulic circuit, the blue electric pump will automatically activate to ensure that critical flight controls can still be operated.
- During cargo door operations, to maintain the hydraulic pressure without running the engines.
- When the landing gear is not in the uplocked position during flight, ensuring landing gear extension if required.
The purpose of these automatic activations is to maintain the redundancy and integrity of the aircraft's hydraulic system. The system ensures the pilots and flight control systems maintain adequate control over the aircraft's primary and secondary flight controls, such as ailerons, elevators, and landing gear operations.
