display (MAP). The MAP cannot be displayed on the PFD if the adjacent
display (DU #2 or DU #3) is already displaying an MFD MAP format.
Weather information can be displayed on the PFD ARC or MAP
format. To the right of the HSI, a Vertical Speed Indicator (VSI) is displayed,
and to the left, navigation information is annunciated.
Comparison monitors provide indications to the pilots that there is a
difference between the data displayed on each PFD. This monitoring is
a function within the IC-600s that compares what is being displayed on
one side with either the cross-side displayed data or the secondary
source data. Should data be out of tolerance between what is being reported
from the source, and what is being sent to the display units, or
if avionics related exceedances are detected, CAS will illuminate.
The following CAS illumination is specific to the PFDs:
The brightness of each PFD is controlled by the DIM control on each respective
display controller. Pilot’s PFD (DU #1) receives 28-vdc power
from the left essential avionics bus by a 15-amp circuit breaker DU 1 located
in the INSTRUMENT/INDICATIONS group of the pilot’s circuit
breaker panel. Copilot’s PFD (DU #4) receives 28-vdc from the right essential
avionics bus by a 15-amp circuit breaker DU #4 located in the
INSTRUMENT/INDICATIONS group of the copilot’s circuit breaker
panel.

BEZEL CONTROLLERS
Many of the display control functions are controlled by the DU bezel
controllers and by the menus displayed on the MFD and EICAS displays.
The PFDs both use the BL-870 bezel controller located at the bottom
of the PFDs. Each has two push buttons and two rotary knobs
(Figure 5-10). The push buttons and rotary knobs have functions dedicated
to decision height, minimum descent altitude and barometric correction.
The MFD and EICAS displays use the BL-871 bezel controllers which
have six push buttons, menu keys, and a rotary knob for menu manipulation.
The push buttons allow selection of functions displayed in the
menus on the MFD. There are three functions that the MFD bezel push
buttons provide - (1) selection of a submenu, (2) toggling the selection
of a menu item and (3) selection of a variable parameter for setting. The
MFD rotary knob is dedicated to the control of the map/plan range.

With weather radar selected for display, the MFD rotary knob will have
no function. The EICAS bezel controller provides dedicated buttons for
the displayed EICAS menu. These buttons toggle the selection of the
EICAS system page displays. The EICAS rotary knob allows for scrolling
of the CAS messages on the EICAS display.
MULTI-FUNCTION DISPLAY (MFD)
The MFD (normally DU #3) provides the flight crew with a means of
displaying a variety of information. In its normal mode it can serve as
a full time weather radar display superimposed on a 120° compass arc.
There are two basic formats available on the MFD, a partial arc (Map)
display, and a plan mode (North up). Like the PFD, the MFD may have
flight plans composed of up to ten connected waypoints imposed on a
compass card. True airspeed (TAS) provided from the ADC and ground
speed (GSPD) provided from the FMS, are displayed on the MFD. Other
information displayed full time include: FMS source, “TO” waypoint,
distance to “TO” waypoint, time-to-go to “TO” waypoint, wind
speed and direction, Static Air Temperature (SAT), and weather radar
(WX) modes.
The MFD also provides a second source for access to EICAS systems
pages as well as providing joystick functions. The MFD (DU #3) may
serve as a backup for any other DU through pilot initiated reversionary
modes.
Other information available on the MFD includes:
• TCAS mode (optional) — Controls the display of TCAS on the
map presentation.
• MFD MENU — Activation of this key will enable the MFD SUBMENU
to appear.
• CHECKLIST PAGE — This key provides entry into the normal
checklist procedure index page.
• SYSTEM PAGE — Selection of this key will access the systems
sub-menu pages which are duplicates of the EICAS system
pages.
28-vdc is provided from the right essential avionics bus by a 15-amp
circuit breaker DU #3, located on the copilot’s circuit breaker panel (INSTRUMENT/
INDICATIONS group).
