MFD/PFD CONTROL UNIT (OPTIONAL)
The optional MFD/PFD Control Unit is a pedestal-mounted user interface allowing for ease of data entry,
MFD/PFD operation, and NAV/COM tuning. Many procedures in this Pilot’s Guide can be performed using
the MFD/PFD Control Unit rather than the display bezel controls. Indicators above the
PFD
,
MFD
,
NAV
, and
COM
keys are illuminated when their respective control mode(s) are selected. The unit is in MFD control mode
by default on system power-up.
NAV/COM radio tuning can be accomplished in either PFD or MFD control mode. The appropriate frequency
box on the selected display is outlined by a light blue selection box, which flashes for a few seconds to indicate
Control Unit activity (refer to the Audio Panel and CNS Section for more information about NAV/COM tuning).
Selection of a different display control or radio tuning mode results in cancelation of the previous radio tuning
mode.
