What equipment is on the A hydraulic system?

• A. Ailerons, Landing Gear, Elevators, Alternate Brakes, Rudders, Nose Wheel Steering, Inboard Flight Spoilers, Number 1 Thrust Reverser, Ground Spoilers
• B. Ailerons, Landing Gear, Elevators, Alternate Brakes, Rudders, Nose Wheel Steering
• C. Ailerons, Landing Gear, Elevators, Rudders, Ground Spoilers
• D. Elevators, Rudders, Nose Wheel Steering, Ground Spoilers

Answer: (A)

The main idea is understanding which components are powered by the A hydraulic system. This system provides hydraulic power to both primary flight controls and several airframe systems needed for taxi, takeoff, and landing. Specifically, it drives the ailerons, elevators, and rudders (the primary control surfaces), plus the landing gear and its retract/extend actuators, the brakes (including alternate brakes), the nose wheel steering, the inboard flight spoilers, the ground spoilers, and the first engine’s thrust reverser. That full set is what the A system powers, so the option that lists all of these components is the best match. Other options omit one or more of these items, making them incomplete representations of what the A hydraulic system powers.
