What equipment is on the B hydraulic system?

• A. Yaw Dampers, Elevators, Ailerons, Rudder, Outboard Spoilers, Flaps, Brakes, Autoslats, LEDs, Landing Gear (retract only), Alternate Nose Wheel Steering, Number 2 Thrust Reverser
• B. Yaw Dampers, Elevators, Ailerons, Rudder, Outboard Spoilers
• C. Yaw Dampers, Elevators, Ailerons
• D. Leading Edge Devices, Ground Spoilers, Ailerons, Rudder, Flaps

Answer: (A)

The B hydraulic system powers the heaviest, most actively moved parts of the airplane: the main flight control surfaces and systems that need high force or redundancy. The full list that fits this system includes yaw dampers, elevators, ailerons, rudder, outboard spoilers, flaps, brakes, autoslats, landing gear (retract only), alternate nose wheel steering, and the number 2 thrust reverser. This combination shows the broad range of components the B system supports, from flight control surfaces to gear and thrust-reversing hardware. The other options omit one or more of these critical items, or mix in components not reliably associated with the B system, making them incomplete representations of what B powers.
