AFCS Quiz 2 Part b

Errors - Detected by Short Term Error sensors

• Short Term

• Long Term

• Both

Name the actuator;

Uses incompressible hydraulic fluid rather than Gas/Air, this increases accuracy and predictability of the mechanical output. Fed from a separate hydraulic supply.

• Electro-Mechanical Actuator

• Electro-Hydraulic Actuator

• Electro-Pneumatic Actuator

• Electro-Hydrostatic Actuator

Name the Movement of Axis for A and C

• Rotation around lateral

• Rotation Around Longitudinal

• Rotation around Vertical

• Acceleration along Longitudinal

Trimming - used to make large, fast changes to datum and can be achieved in two way.  Firstly, move the Control Column, when the control column is at the new position, press and release the Trim Release Switch, this will disengage the motor within the parallel actuator allowing the artificial feel spring to un-wind to a new datum position, the pilot now can release the grip with the control column now held at the new datum

• System/Auto Trim

• Manual Manoeuvre

• Manual Trim

Name the actuator:

Systems that have both hydraulic and electric technology in a self-contained package

• Electro-Hydraulic Actuator

• Electro-Hydrostatic Actuator

• Electro-Mechanical Actuator

• Electro-Pneumatic Actuator

Errors - Caused by local variations of air pressure (turbulence).

• Long Term

• Short Term

• Both

Name the correct actuator:

Full Authority, the same amount of control movement as when the pilot moves the controls. However is slower in operation.

• Series

• Parallel
