Yaw Damper
To ensure proper yaw damper operation, the Before Taxi yaw
damper operational check in AFM Section II must be success-
fully completed before each flight.
Yaw damper should be turned off while using rudder trim.
Reengage yaw damper after trim is established.
On aircraft with FC-200 autopilot, both yaw dampers must be
operative. One yaw damper must be on and operative for all
flight conditions except takeoff, landing touchdown, and for
trimming rudder. For a normal landing, the following proce-
dures apply:
Q
aircraft shall be configured for landing at least 500 ft AGL
Q
yaw damper shall be disengaged during the landing flare.
On aircraft with FC-530 autopilot, one yaw damper must be
on and operative for all flight conditions except takeoff and for
trimming rudder. For landing, one yaw damper must be on
except as permitted in Abnormal Procedures (AFM Section IV).
For anticipated turbulence due to gusty winds, wake turbu -
lence, or wind shear, increase the approach speed. In gusty
wind conditions, an increase in approach speed of
1/2 the gust
factor is recommended.
Information shown in italics is not included in the AFM Limitations chapter.
CAUTION: During landings in turbulent air conditions with
the yaw damper off, the aircraft may exhibit undesirable lat-
eral-directional (Dutch-roll) characteristics. These character-
istics improve as the wing/tip fuel is consumed. Observe the
following relative to turbulence contained in the Approach
procedure (AFM Section II) and increase airspeed as
required.
