How many hydraulic systems does the 737-800 have?

The Boeing 737-800 is equipped with three hydraulic systems, which serve various critical functions throughout the aircraft. These hydraulic systems are vital for the operation of the flight control surfaces, landing gear, and brakes, among other systems. Each is designed to operate independently to ensure redundancy and reliability in case one system encounters a failure.

This design enhances safety and operational efficiency by distributing the hydraulic load across multiple systems. The three systems are typically identified as the left, right, and center hydraulic systems, each responsible for different functions and components of the aircraft. Understanding the configuration of these hydraulic systems is crucial for pilots and maintenance personnel alike, as it aids in troubleshooting and ensures that operational protocols are followed for the safe handling of the aircraft.
