Final answer:
The statement is true; in systems designed with redundancy, the B pump is automatically activated if an EDP fails when the switches are in AUTO.
Step-by-step explanation:
The question refers to the operation of hydraulic systems, specifically within the context of aerospace engineering or similar fields where Hydraulic Pump switches are utilized. When hydraulic pump switches are set to AUTO, the system is designed to automatically activate the backup or auxiliary pump, also known as the B pump, in the event of a failure of the primary Engine-Driven Pump (EDP), designated as 1A or 2A. This automatic activation ensures continuity of the hydraulic functions that are critical for operations such as controlling flaps, gears, and other essential mechanical components in aircraft or heavy machinery. Thus, the statement about the loss of an EDP automatically activating the associated B pump is generally true. However, it is important to note that specific system designs can vary, and this description assumes a typical system setup where redundancy is designed into the hydraulic system to ensure reliable operation.
