(CMD) or control wheel steering (CWS), the MCP sends engage
signals go to the FCCs. When the crew turns on either flight
director, the MCP sends F/D turn on signals to the FCCs.
You energize the master test relay when the master test switch
is in the test position. This sends 28v dc to do a test of the MCP
light emitting diodes (LEDs).
FCC
Each FCC sends data to the MCP to tell the MCP if it can engage
the A/Ps. To engage an A/P, the FCC must send an engage
solenoid enable high signal and an engage solenoid enable low
signal. The enable high signals shows that CPU 1 in the FCC is
valid. The enable low signals shows that CPU 2 in the FCC is
valid. Each FCC also tells the MCP which FCC is the master
FCC. The MCP uses data from the master FCC and also sends
the master FCC data on to other systems.
The FCCs send test, synchronization, and autopilot disconnect
signals between each other.

General
The FCCs and MCP have an interface with these components
when a roll mode is active for the autopilot:
* A/P aileron actuators A and B
* Roll CWS force transducer
* Aileron position sensor
* Spoilers 4 and 9 position sensors.
Aileron A/P Actuators
The A/P aileron actuators send the aileron actuator position
data to the onside FCC. This position data comes from the linear
variable differential transformer (LVDT).
MCP
When you engage the A autopilot to CMD or CWS, the MCP
sends an engage signal to A/P aileron actuator A. This lets A
hydraulic fluid into the actuator. The MCP also sends this signal
to FCC A. The FCC then commands the actuator main piston to
synchronize to the aileron position. When you engage the B
autopilot to CMD or CWS, the MCP sends an engage signal to
A/P aileron actuator B. This lets B hydraulic fluid into the
actuator. The MCP also sends this signal to FCC B. The FCC
then commands the actuator main piston to synchronize to the
aileron position.
Roll CWS Force Transducer
The roll CWS force transducer sends a signal to the FCCs. This
signal is in proportion to the turning force on the control wheels.
Aileron Position Sensor
The aileron position sensor measures the position of the
ailerons. It sends a signal in proportion to this position to the
FCCs.
Spoiler Position Sensors
One spoiler position sensor measures the position of spoiler 4.
Another spoiler sensor measures the position of spoiler 9. The
sensors send position signals to the FCCs.
FCC
The FCC A sends a signal to A/P aileron actuator A to engage
the detent solenoid valve. This pressurizes the main piston and
locks it to the output shaft. It also sends the roll command
signals to this actuator. The FCC B sends a signal to A/P aileron
actuator B to engage the detent piston. This pressurizes the
main piston and locks it to the output shaft. It also sends the roll
command signals to this actuator.
Each FCC sends its onside aileron position data to the other
FCC.
