Flight director modes are normally selected independently for the pitch and roll axes.  Unless otherwise

specified, all mode keys are alternate action (i.e., press on, press off). In the absence of specific mode selection,
the flight director reverts to the default pitch and/or roll modes(s).

Armed modes are annunciated in white and active in green or magenta (if the mode reference is provided by 

the GPS navigation function) in the AFCS Status Box. Under normal operation, when the control for the active
flight director mode is pressed, the flight director reverts to the default mode(s) for the axis(es). Automatic
transition from armed to active mode is indicated by the white armed mode annunciation moving to the active 
mode field and flashing for 5 seconds.

If  the  information  required  to  compute  a  flight  director  mode  becomes  invalid  or  unavailable,  the  flight

director automatically reverts to the default mode for that axis. A flashing yellow mode annunciation indicates
loss of sensor (ADC) or navigation data (VOR, LOC, GPS, VNV, SBAS) required to compute commands. When
such a loss occurs, the system automatically begins to roll the wings level (enters Roll Hold Mode) or maintain
the pitch angle (enters Pitch Hold Mode), depending on the affected axis. The flashing annunciation stops
when the affected mode key is pressed or another mode for the axis is selected. After 5 seconds, if no action is 
taken, the flashing annunciation stops and the flight director enters the default mode for the affected axis.

The flight director is automatically disabled if the attitude information required to compute the default flight

director modes becomes invalid or unavailable.

The GFC 700 flight director can be coupled to either the pilot-side or copilot-side PFD data using the CPL 

Key. When the pilot-side or copilot-side data source is changed, the vertical and lateral modes revert to default.
The autopilot follows the selected flight director only, indicated by an arrow pointing toward either the pilot or 
copilot side, in the center of the AFCS Status Box.

The currently active flight director may be turned off and the Command Bars removed from the displays 

by pressing the active FD Key again. Pressing the FD Key for the inactive flight director only removes the 
Command Bars from the corresponding display.  The FD key for the selected flight director is disabled when 
the autopilot is engaged.
