has been averaged for twenty
seconds, the process is complete
and the screen will show:
At this time, press and
quickly release the encoder
knob to confirm the calibration
and enter the resulting data into
permanent memory.
If the “
YAW DAMPER?
”
question was answered “
Y
” and
the “
MAG CALIBRATE?
” question
was answered “ N ” the next
screen in the setup sequence
will allow adjustment controls
for the yaw damper:
The value for leveling is
adjustable from -8 to 8 and is
used as necessary to have the
yaw damper keep the aircraft
slip/skid indicator (ball)
centered when the yaw damper
is engaged and the autopilot is
flying the aircraft straight and
level. When adjusting this
value, allow a few seconds for
the yaw damper to respond to
each new value setting. Press
and release the encoder know
once the correct setting has
been determined.
Use the encoder knob to
determine the correct amount of
yaw damper response in
conditions of light to moderate
turbulence. Having found a
satisfactory value for flight in
turbulence, press and release the
encoder knob to enter the value
into storage.

This concludes the DFC-
250 lateral setup mode.
Pitch Setup
The pitch (vertical) setup
consists of setting activity and
torque in a manner similar to
that done for the aileron servo
in the lateral setup. To enter the
vertical setup mode, press and
hold the [ALT] button for two
or more seconds, until the first
setup screen appears. This
screen shows current values for
the activity and torque of the
aileron servo with an underline
under the present setting of
activity. A typical screen might
show
YD LEVELING __0
YD ACTIVITY 6
VRT ACTIVITY 8
VRT TORQUE 200
Turn the encoder knob to
set the activity level to the
desired value for the particular
aircraft. Any value between 0
and 12 may be chosen. In this
example, the value of 4 will be
selected.
Once activity is set to the
desired value, press and quickly
release the knob to confirm and
enter the selected value into
storage. The underline (cursor)
YD LEVELING 0
