4.6.7 Vertical Speed Bug Coupling
Certain autopilots may be coupled to the PFD vertical speed bug for maintaining
a selected vertical speed. Except as described in this section, refer to the
autopilot AFMS and/or Pilot's Guide for autopilot system operation.
4.6.7.1 S-Tec Autopilots
To select and maintain a vertical speed:
1. Select the desired vertical speed with the PFD vertical speed bug.
2. Press VS on the autopilot programmer computer to engage vertical
speed mode.
The selected vertical speed will automatically be reduced
towards zero when approaching the selected altitude bug.
AUTO will appear in the vertical speed PFD knob mode
indicator when vertical speed is being reduced automatically.
Manually changing the selected vertical speed while AUTO is
displayed will cancel automatic vertical speed reduction.
4.6.7.2 Bendix/King Autopilots
To select and maintain a vertical speed:
1. Press and hold the VS button on the PFD to synch the VS to current
vertical speed and engage vertical speed mode.
2. Select the desired vertical speed with the PFD vertical speed bug.
When VS mode is engaged, the VS bug will be synced to the
aircraft's current vertical speed and the selected VS with flash
momentarily. VS is displayed in green text in the upper right
corner of the PFD to indicate that VS mode is engaged.
While VS mode is engaged, the vertical speed bug may be changed by:

Adjust the vertical speed bug with the PFD knob, or

Press and hold the vertical trim rocker switch on the autopilot in the
desired direction, or

Press the CWS button on the control wheel to synchronize the vertical
speed bug to the current vertical speed.
