The display bezel is equipped with two dual-concentric knobs (DCKs). These DCK knobs have a large outer knob and a small inner knob that can be used for system navigation on the display. After navigating to specific locations on the display, the DCK knobs can be pressed inward to select the highlighted button. On the PFD the DCKs are pilot configurable and can be used for altitude bug selection, heading bug adjustments, barometric pressure adjustments, course adjustments, communication radio tuning, and communication radio volume. If the DCKs are pressed while on the PFW they will sync the heading bug to the current aircraft heading, sync the barometric pressure between standard atmospheric pressure (STD) and the previous barometric setting, switch between COM1 and COM2 (if multiple communication radios are configured), and/or squelch the active communication radio depending on pilot configuration.

The default settings on the PFD for the left DCK controls the altitude bug (outer knob) and heading bug (inner knob). Pressing the left DCK will sync the heading bug to the current aircraft heading. The default setting for the right inner DCK will control the HSI course selection (in OBS mode) or the VLOC course, depending on the current CDI source. The default setting for the right outer DCK will control the barometric setting. Pushing the right DCK will adjust the barometric setting to the standard (STD) setting. Using the DCKs for radio controls is also available to be configured by the pilot. The COM Tuning function will allow the user to adjust the standby frequency of the active communication radio; The outer knob adjusting the MHz, the inner DCK adjusts the decimal places of the frequency, and pushing the knob switches between COM1 and COM2 (if two communication radios are configured). The COM Volume function will allow the pilot to control the squelch (push the DCK then turn to adjust) or adjust the volume of the active radio.

The MFW does not support pilot configuration. The controls the DCKs on the MFW provide control of the specific application or window that is being displayed.

When the display is in split screen mode (PFW/MFW) the DCK on the PFW side of the display will continue to control the default setting for that DCK. The function of the DCK knob is displayed above it to show the user what it controls. The ability to switch the DCK controls is accessed through the PFW Settings window.
