SECTION 6: AUTOMATIC FLIGHT
CONTROL
NOTE: The information in this section is not
applicable to the M20TN aircraft. Refer to the
pilot’s guide for the installed autopilot system.
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 wheel, pressing this
button disengages the autopilot. Pressing it also
acknowledges an autopilot disconnect.
• CWS (Control Wheel Steering) Button —
Located on the pilot’s control wheel, 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.
• GA (Go Around) Button — Located on the
instrument panel, the GA Button disengages the
autopilot and selects the Go Around Pitch and Roll
(wings level) modes.
• MET (Manual Electric Trim) Switch — This
switch is used to operate manual electric pitch trim.
Moving both switches forward simultaneously trims
the aircraft nose down. Moving both switches aft
simultaneously trims the aircraft nose up. The left
switch is the ARM contact and the right switch
controls the up/down trim. Pressing the ARM Switch
disengages the autopilot, if currently engaged. If
one side of the switch is active for more than three
seconds without the other side also being active,
‘PTRM’ is displayed in the AFCS System Status field
on the PFD. Pressing the MET ARM Switch also
acknowledges an autopilot disconnect.
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.
