Selected Flight Guidance Computer-Oneof two green arrows will
illuminate and point to the flight guidance system, pilot or copilot,
that the autopilot will use as a source of steering commands.

CONTROL WHEEL MASTER SWATCHES - AUTOPILOT FUNCTION
The Control Wheel Master Switches (MSW), located on the outboard
horn of the pilot's and copilot's control wheels, may be used to disengage
the autopilot. Depressing either the pilot's or copilot's Control
Wheel Master Switch (MSW) will apply a signal which cancels the autopilot
engage signal. When the autopilot disengages, the green light
above theAP button will extinguish and the autopilot disengage tone
will sound. When the autopilot is disengaged using the Control
Wheel Master Switches (MSW), the flight director will remain active
and will display steering information from the flight guidance com-
TRIM SELECTOR SWITCH -AUTOPILOT FUNCTION
When the autopilot is engaged, the autopilot maintains aircraft pitch
trim through the secondary motor of the horizontal stabilizer pitch
trim actuator if the PITCH TRIM selector switch on the pedestal is in
the PRI or SEC position. The autopilot will not engage or will disengage
if the PITCH TRIM selector switch is moved to the OFF position.

CONTROLWHEELTRIM SWITCHES-AUTOPILOT/FLIGHT DIRECTOR
FUNCTION
The control wheel trim switches, located on the outboard horn of each
control wheel, may be used to disengage the autopilot, to make trim
adjustments with the autopilot pitch and roll axes inhibited, to make
vertical and lateral inputs while in certain modes and to toggle between
normal and high speed profiles while operating in CLBor DES
mode. When either control wheel trim switch (arming button depressed)
is moved to any of the four positions (LWD, RWD, NOSE
UP, or NOSE DN) the autopilot will disengage, the green light above
the AP button will extinguish and the autopilot disengage tone will
sound. When the autopilot is disengaged using the control wheel trim
switches, the flight director will remain active and will display steering
information from the flight guidance computer. Control wheel
trim switches (arming button not depressed), may be used to insert
vertical and lateral changes when ALTHOLD, MACH,VS, LAS, Pitch
Attitude Hold or Roll Attitude Hold are engaged. To make a vertical
command input, the control wheel trim switch (arming button not depressed)
is moved to NOSE UP or NOSE DN. To make a lateral command
input, the control wheel trim switch (arming button not depressed)
is moved to LWD or RWD. When the autopilot is engaged,
pitch and roll trim changes can be made by holding the CWS switch
and using the control wheel trim switches as discussed in PITCH
TRIM SYSTEM andROLL TRIM SYSTEM.
Vertical Command-In Pitch Attitude Hold, commands a change in
the aircraft's pitch attitude; In ALT HOLD, increases or decreases the
reference altitude; In MACH, increases or decreases the reference
Mach number; In VS, increases or decreases the reference vertical
speed, In IAS, increases or decreases the reference indicated airspeed;
In CLB or DES, toggles between normal and high speed profiles. Initiating
vertical command while operating in the VNAV, Glideslope
Capture, Altitude Capture or Go-around mode will cancel those
modesand the system will revert to Pitch Attitude Hold mode.
Lateral Command-In Roll Attitude Hold, commands a change in
the aircraft's roll attitude. Initiating lateral command while operating
in the HDG, NAV Capture or APR Capture mode will cancel those
modes and the system will revert to Roll Attitude Hold mode.

PEDESTAL NOSE DN-OFF-NOSE UP SWITCH - AUTOPILOT
FUNCTION
The NOSE DN-OFFNOSE UP switch, located on the pedestal trim
control panel, maybe used to disengage the autopilot or to make trim
adjustments with the autopilot pitch and roll axes inhibited. With the
PITCH TRIM selector switch in the SEC position, actuation of secondary
pitch trim through theNOSE DNOFFNOSE UP switch will disengage
the autopilot, extinguish the green light above the AP button,
and sound the autopilot disengage tone. When the autopilot is disengaged
through the NOSE DNOFF-NOSE UP switch, the flight director
will remain active and will display steering information from the
flight guidance computer. When the autopilot pitch and roll axes are
inhibited using the control wheel CWS switches, pitch trim changes
