CHAPTER 5: AIRCRAFT
Steering (CWS) button is depressed during fl ight director
mode the ALT function if selected will trip off and will need
to be reset when desired. If a climb or descent is necessary,
use CWS to initiate the necessary pitch attitude and dial
the desired level-off altitude into the SET ALTITUDE box.
Once the altitude change has commenced select ALT SEL
and the command bars will indicate when altitude level-
off is required. Additionally, once the desired pitch attitude
has been set and VS has been selected the command
bars will indicate the amount of pitch change required to
maintain the chosen vertical speed. If the VS button is not
used then the command bars will simply direct the pilot to
maintain the selected pitch attitude. Electric trim may be
utilized during this mode of fl ight control.
To operate in basic autopilot mode, simply press the AP
ENG button on the avionics panel. This activates the Yaw
Damper (YD) and Autopilot (AP) which by itself is the most
basic functional mode. In this mode you may depress and
hold the Control Wheel Steering (CWS) button on the left
side of the yoke to make pitch and heading changes. When
the CWS button is released the aircraft will hold the current
heading and maintain the current pitch attitude. This is
NOT necessarily an altitude hold feature. The command
bars will not be present during this type of operation.
During this operation the control knob may also be used
to make pitch and heading changes, however, the control
knob will only select a rate of vertical speed and/or bank
angle. The resultant amount of vertical speed and bank
angle is dependent upon the degree of knob defl ection.
The rocker switch on the autopilot portion of the AP-3000
may be used in place of the control knob for vertical speed
