choose to hand fly the aircraft with "raw data" (flight directors not displayed), hand fly the aircraft using the flight director
command bars, or couple the autopilot to the flight director.
COMPONENTS AND OPERATION
The flight director (and autopilot and yaw damper) processing is done within two flight guidance computer cards in the
integrated avionics processor system (IAPS). The left and right flight guidance computer cards are identical. During precision
approach and go-around modes, each flight director provides guidance to the onside displays. In all other flight director
modes, only one flight director provides guidance to both left and right flight displays.
The pilot flying can select the onside flight director using the transfer (XFR) button on the flight guidance panel.
If the active flight director fails, a red boxed FD appears on the primary flight display and a cyan FD1(2) FAIL CAS message
is displayed. Selecting the XFR switch on the FGP deselects the failed flight director and allows the functional flight
director to become active.
FLIGHT DIRECTOR COMMAND BARS
The flight directors provide visual pitch and roll control guidance by means of single cue inverted V-shaped command bars,
or cross-pointer command bars. The selection of the preferred display of command bars is made by pushing the REF button
to show page 3/3 on the PFD. The flight director command bars provide visual guidance to the pilot regardless of the autopilot
engagement mode.

FLIGHT GUIDANCE MODE DISPLAY AREA
Lateral and vertical FD modes are presented in the flight mode annunciator display on each PFD. The flight guidance mode
display area is located above the attitude indicator.
The mode display area is divided into three sections, separated by two gray vertical lines. The left section displays lateral
modes. The center section displays the autopilot, yaw damper, and active flight director status. The right section displays
vertical modes. Active modes are displayed in green on the top line and armed modes are displayed in white on the bottom
line.

FLIGHT GUIDANCE PANEL (FGP)
The FGP is the mode selection panel that selects and controls the flight director, autopilot, and yaw damper functions. The
FGP is located on the glare shield and is accessible to both pilots. The FGP is divided by the functional areas they perform.
Those fuctional areas are:
- Flight director/course
- Lateral modes
- Vertical modes
- Autopilot
The flight guidance panel controls are as follows:
FD button — The FD 1 and 2 buttons are used to select and deselect the onside flight director. The flight director is the
lateral and vertical steering commands and the text messages representing the selected modes. Push the FD button to select
the onside flight director. When the flight director is activated using the FD button, the basic modes pitch and roll are automatically
selected. With the FD active, push the FD button to deselect the flight director. With the autopilot engaged and
the flight director showing, deselection of the flight director using the FD button removes the steering commands and not
the text messages, however, the flight director continues to supply steering commands to the autopilot.
CRS knob — A course set knob (CRS) is located at each end of the FGP. These knobs individually set the courses on the
left and right PFD HSI displays. The CRS knob primarily set the course for a VOR radial or LOC course. The course knobs
have a push button in the center to synchronize the display to the aircraft “direct-to” course.
