How many primary hydraulic systems does the 787 have and how are they powered?

Explanation:
Three primary hydraulic systems exist on the 787, named left, center, and right. The left and right systems are normally powered by engine-driven pumps on their respective engines. The center system is designed to be powered by both engine-driven pumps and electric pumps, reflecting the 787’s more-electric aircraft approach. This dual source setup provides hydraulic power to all three systems even if one source isn’t available, ensuring redundancy for flight controls and other hydraulics.
