SECTION 6: AUTOMATIC FLIGHT
CONTROL
In addition to the AFCS (Automatic Flight Control
System) keys on the MFD, as discussed in the System
Overview section, the following buttons and switches
used by the AFCS are located in the cockpit separately
from the PFD and MFD.
• AP DISC (Autopilot Disconnect) Button —
Located on the pilot’s control stick, pressing this
button disengages the autopilot. Pressing it also
acknowledges an autopilot disconnect.
• CWS (Control Wheel Steering) Button — Located
on the pilot’s control stick, pressing and holding the
CWS button disengages the control surface servos
without disengaging the autopilot. If the flight
director has not been activated, pressing the CWS
button will activate the flight director in the default
pitch and roll hold modes.
• GO AROUND Button — Located on the instrument
panel, the Go Around Button disengages the
autopilot and selects the Go Around (wings level)
mode.
• MET (Manual Electric Trim) Switch — This
switch is used to operate manual electric pitch trim.
Moving the switch forward trims the aircraft nose
down. Moving the switch aft trims the aircraft nose
up.
Figure 6-1 AFCS Keys
Pressing the FD Key activates only the flight director
in the default Pitch Hold/Roll modes without engaging
the autopilot. Pressing the AP Key activates the flight
director, and engages the autopilot. When only the flight
director is engaged, pressing the FD Key disengages the
flight director.
Upon activation of the autopilot and/or flight director,
command bars are displayed on the PFD. If the attitude
information being sent to the flight director becomes
invalid or unavailable, the command bars are removed
from the display.
