What are the typical components of a hydraulic system in flight?

• A. Turbine blades and combustors.
• B. Pumps, reservoirs, lines, and actuators; transmit power to flight controls, landing gear, and brakes.
• C. Electrical bus networks and power conversion equipment.
• D. Pneumatic tubes for cabin pressurization.

Answer: (B)

Hydraulic systems in flight move control surfaces, gear, and brakes by using fluid under pressure to transmit power. The core pieces are a pump that pushes fluid from a reservoir, through lines, to an actuator that converts that fluid pressure into motion. The reservoir stores the hydraulic fluid, keeping it ready for use; lines carry the pressurized fluid to the actuators; and the actuators—often hydraulic cylinders or motors—produce the actual movement. Valves regulate where the fluid goes, while filters keep debris out and heat exchangers manage temperature. Accumulators can smooth pressure changes and store a bit of energy for responsive actions. So the combination of pumps, reservoirs, lines, and actuators is the typical setup that delivers power to flight controls, landing gear, and brakes. The other options describe engine components, electrical system hardware, or cabin pressurization, which are not part of the hydraulic system.
