2. Aircraft systems - Wikipedia

   en.wikipedia.org/wiki/Aircraft_systems

   A hydraulic system is required for high speed flight and large aircraft to convert the crews' control system movements to surface movements. The hydraulic system is also used to extend and retract landing gear, operate flaps and slats, operate the wheel brakes and steering systems.

3. Power transfer unit - Wikipedia

   en.wikipedia.org/wiki/Power_transfer_unit

   The Citation X business jet is one such aircraft with a uni-directional PTU, protected by check-valves and a back-pressure stall line, designed to allow the right hand hydraulic system to assist the left hand hydraulic system and the left hand auxiliary motorpump to retract the landing gear during a port engine failure only.

4. Electro-hydraulic actuator - Wikipedia

   en.wikipedia.org/wiki/Electro-hydraulic_actuator

   All these systems require three separate components, the hydraulic supply system, the valves and associated control network, and the actuators. Since any one of these systems could fail and render the aircraft inoperable, redundancies are needed that greatly increase the complexity of the system.

5. Engine-indicating and crew-alerting system - Wikipedia

   Other aircraft systems typically monitored by EICAS are for example hydraulic, pneumatic, electrical, deicing, environmental and control surface systems. EICAS has high connectivity & provides data acquisition and routing. [2] EICAS is a key function of a glass cockpit system, which replaces all analog gauges with software-driven electronic ...

6. Aircraft flight control system - Wikipedia

   en.wikipedia.org/wiki/Aircraft_flight_control_system

   Cockpit controls and instrument panel of a Cessna 182D Skylane. Generally, the primary cockpit flight controls are arranged as follows: [2] A control yoke (also known as a control column), centre stick or side-stick (the latter two also colloquially known as a control or joystick), governs the aircraft's roll and pitch by moving the ailerons (or activating wing warping on some very early ...

7. Yoke (aeronautics) - Wikipedia

   en.wikipedia.org/wiki/Yoke_(aeronautics)

   Small to medium-size aircraft, usually limited to propeller-driven, feature a mechanical system whereby the yoke is connected directly to the control surfaces with cables and rods. Human muscle power alone is not enough for larger and more powerful aircraft, so hydraulic systems are used, in which yoke movements control hydraulic valves and ...
