SECTION III
MODEL 560 INSTRUMENTATION AND AVIONICS
DISPLAY CONTROLLER
The display controllers, located on the left and right of the instrument panels, allows selection of the
different formats and provides for selection of required navigation sources and bearing data.
The individual controls are:
SC/CP: Selects flight director command mode. Alternate action toggling between single
cue and cross pointer flight director display. Power up state is single cue.
GS/TTG Button: Ground speed (GS) or time-to-go (TTG) is displayed in the lower right center of
the EHSI. Pressing the GS/TTG button provides alternating selection of GS or
TTG to next station or waypoint.
ET Button: Controls elapsed timer that appears in the EHSI location dedicated to
GSPD/TTG. Initial actuation enters the mode at the previous position. If elapsed
time is being displayed, stops the display. Sequence of the ET button is:
Reset - Elapsed Time - Stop - Repeat.
NAV Button: Pressing the NAV button selects the VOR for display on the EHSI course
deviation indicator (CDI). Pressing the button alternately selects NAV 1 and NAV
2 (annunciated VOR 1 and VOR 2 on the center right side of the EHSI; ILS 1 and
ILS 2, if ILS frequency is tuned in NAV). The flight director interfaces with the
NAV that is selected and displayed on the EHSI.
FMS Selects flight management system (FMS) for display on the EHSI; the flight
director will interface with the FMS. The EHSI course needle represents FMS
course information on the bearing pointer.
BRG " O " Knob This knob has four positions. The OFF position removes the bearing pointer
from the display. In NAV position, VOR 1 bearing information is displayed. In
ADF position, ADF 1 bearing is displayed. Selecting FMS displays FMS.
PFD DIM (Outer The DIM knob sets the overall brightness of the PFD. When a reference level is
Concentric) set, photoelectric sensors will maintain the relative brightness level in various
lighting conditions. Full counterclockwise OFF position turns off the PFD, and
will revert the display, through an EFIS backup mode, to the multifunction display.
EFIS backup is provided by the MFD as an addition to the existing symbol
generator (EFIS) reversionary modes. In case of failure of a primary flight display
(PFD) cathode ray tube, selection of an EFIS backup mode can be accomplished
by turning OFF the PFD DIM button on the affected PFD. The MFD will then
take up the display selected on that controller. If both PFDs are OFF, the
copilot’s PFD will have priority on the MFD display.
