INDEX
The following AFCS controls are located in the cockpit separately from the MFD:
AP DISC Switch
(Autopilot Disconnect)
Disengages the autopilot and interrupts pitch trim operation
This switch may be used to mute the aural autopilot disconnect alert.
The
AP DISC
Switch is located on each control stick.
CWS Button
(Control Wheel Steering)
While pressed, allows manual control of the aircraft while the autopilot is
engaged and synchronizes the flight director’s Command Bars with the current
aircraft pitch (if not in Glideslope Mode) and roll (if in Roll Hold Mode)
Upon release of the
CWS
Button, the flight director may establish new
reference points, depending on the current pitch and roll modes. CWS
operation details are discussed in the flight director modes section.
The
CWS
Button is located on the top of the left control stick.
GA Button (Go Around)
Disengages the autopilot and selects flight director Go Around Mode
If an approach procedure is loaded this switch also activates the missed
approach when the selected navigation source is GPS or when the navigation
source is VOR/LOC and a valid frequency has been tuned.
The
GA
Button is located on the left throttle handle.
AP TRIM Switch
(Autopilot Trim)
Used to command manual electric trim (MET)
This composite switch is split into left and right sides. The left switch is
the ARM contact and the right switch controls the DN (forward) and UP
(rearward) contacts. The
AP TRIM
ARM switch can be used to disengage
the autopilot and to acknowledge an autopilot disconnect alert and mute the
associated aural tone.
Manual trim commands are generated only when both sides of the switch
are operated simultaneously. If either side of the switch is active separately for
more than three seconds,
MET function is disabled and ‘PTRM’ is displayed
as the AFCS Status Annunciation on the PFD. The function remains disabled
until both sides of the switch are inactivated.
The
AP TRIM
Switch is located on the left control stick.
