See the speedbrake control system section for more
information on the speedbrake control system.
(SECTION 27-62)
When the speedbrake handle moves, it gives an input to the
speedbrake lever position sensor. The speedbrake lever
position sensor provides an input to the FDAU.
When the flight spoilers move, they give an input to the spoiler
position transmitters and the spoiler position sensors. The
spoiler position transmitters provide an input to the FDAU. The
spoiler position sensors provide an input to the FCCs.

General
These are the components of the flight spoiler control system:
* Spoiler control quadrant
* Spoiler ratio changer
* Spoiler mixer
* Flight spoiler actuator quadrants
* Flight spoiler actuators.
The flight spoiler control system receives inputs from the
control wheels and the speedbrake lever.
Spoiler Control Quadrant
The spoiler control quadrant receives inputs from the control
wheels and the aileron PCUs through the aileron spring
cartridge. The quadrant sends these inputs to the spoiler ratio
changer.
Spoiler Ratio Changer
The spoiler ratio changer receives inputs from the spoiler
control quadrant and the speedbrake lever. The ratio changer
sends the commands to the spoiler mixer. The commands then
go from the spoiler mixer through the ratio changer to the flight
spoiler actuator quadrants.
Spoiler Mixer
The spoiler mixer combines the inputs from the spoiler control
quadrant and the speedbrake lever. The spoiler mixer then
sends the flight spoiler commands back to the ratio changer and
sends the ground spoiler commands to the ground spoiler
control valve. The ground spoiler control valve permits the
ground spoilers to operate.
See the speedbrake control system section for more
information on the ground spoilers and the ground spoiler
control valve. (SECTION 27-62)
Flight Spoiler Actuator Quadrants
The flight spoiler actuator quadrants send the commands to the
flight spoiler actuators.
Flight Spoiler Actuators
The flight spoiler actuators use hydraulic power to move the
flight spoilers.
