Many of the controls on the MFD Control Unit (GCU 475) have the same function as those located on the 

MFD.

The following list provides an overview of the controls located on the MFD Control Unit (see Figure 1-3):

  Dual FMS Knob – Flight Management System Knob.  This knob selects the MFD page to be viewed; the 

large knob selects a page group (MAP, WPT, AUX, NRST), while the small knob selects a specific page 
within the page group.  Pressing the FMS Knob turns the selection cursor ON and OFF.  When the cursor 
is ON, data may be entered in the applicable window by turning the small and large knobs.  In this case, 
the large knob moves the cursor on the page, while the small knob selects individual characters for the 
highlighted cursor location.

  Direct-to Key – Allows the user to enter a destination waypoint and establish a direct course to the selected 

destination (the destination is either specified by the identifier, chosen from the active route, or taken from 
the map pointer position).

  FPL Key – Displays the active Flight Plan Page for creating and editing the active flight plan, or for 

accessing stored flight plans.

  MENU Key – Displays a context-sensitive list of options.  This list allows the user to access additional 

features or make setting changes that relate to particular pages.

  PROC Key – Gives access to IFR departure procedures (DPs), arrival procedures (STARs) and approach 

procedures (IAPs) for a flight plan.  If a flight plan is used, available procedures for the departure and/or 
arrival airport are automatically suggested.  Theses procedures can then be loaded into the active flight 
plan.  If a flight plan is not used, both the desired airport and the desired procedure may be selected.

  Joystick – Changes the map range when rotated.  Activates the map pointer when pressed.
