AUTOMATIC FLIGHT CONTROL SYSTEM
The following AFCS controls are located separately from the AFCS Control Unit:
AP DISC Switch
(Autopilot
Disconnect)
Disengages the autopilot, yaw damper, and flight director and interrupts pitch trim
operation
An AP DISC Switch is located on each control wheel.
This switch may be used to acknowledge an autopilot disconnect alert and mute the
associated aural tone.
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 a Vertical Navigation, Glideslope, or Glidepath Mode) and roll (if in Roll Hold
Mode)
A CWS Button is located on each control wheel.
Upon release of the
CWS Button, the flight director may establish new pitch and roll
references, depending on the current vertical and lateral modes. CWS operation
details are discussed in the respective mode sections of this manual.
GA Switch
(Go Around)
Disengages the autopilot and selects flight director Takeoff (on ground) or Go Around
(in air) 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 Switch is located on the throttle.
MEPT Switch
(Manual Electric
Pitch Trim)
Used to command manual electric pitch trim
An MEPT Switch is located on each control wheel.
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.
Pushing the
MEPT ARM Switch disengages the autopilot, if currently engaged, but
does not affect yaw damper operation. The MEPT ARM Switch may be used 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, MEPT function is disabled and ‘PTRM’ (Pitch Trim Failure) is displayed as
the AFCS Status Annunciation on the PFDs. The function remains disabled until
both sides of the switch are inactivated.
MEYT Switch
(Manual Electric
Yaw Trim)
Used to command manual electric yaw trim
An MEYT Switch is located on each control wheel.
