190-02177-02 Rev. A
Disengages the autopilot and interrupts pitch trim operation
The AP DISC Button is located on the pilot's control yoke.
This switch may be used to mute the aural autopilot disconnect alert.
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 pilot's control yoke.
The autopilot remains engaged and selects flight director Go Around Mode
If an approach procedure is loaded this button 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 instrument panel above the throttle.
Used to command manual electric trim.
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 MET 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 MET Switch is located on the pilot's control yoke.
