SENSOR DISPLAY UNIT (SDU)
The
SDU is an electronic RMI display that uses a 3 X 3-inch . high-
resolution
monochrome CRT to display airplane heading and backup
navigational data . The
single
SDU is
installed
in
the center instrument
panel between the radio tuning units . The SDU
is able to display data
from either VOR/MS receive,
either
DME, one or two VLF/Omega
receivers,
one or two MLS receivers, and one or two FMS systems .
Airplane
heading A obtained
from
AHS 1 and is displayed with all
SDU formats .
COURSE
HEADING PANEL (CHP)
The single CHP is located forward of the CDUs in the
pedestal . The
CHP provides the selected course and selected heading controls for the
course arrows and heading bugs on the PFDs/MFDs .
The course knobs (CRS 1 & 2) are used to change the
active selected
course on the on-side PFD/MFD when VOR is the active NAV sensor .
When
FNS is the
active
NAV sensor and in the SEL CRS mode, these
knobs change the
course angle to the TO waypoint . Pressing the center
PUSH DIRECT switch on either CRS knob will
zero the course
deviation and establish a course directly to the active
NAV sensor .
The
HDG knob between the CRS 1 & 2 knobs is used to change the se-
lected heading indicated
by the heading bug on both PFDs and MTDs
simultaneously . Pressing the inset PUSHSYNC
switch in the center of
the H DG knob
will
synchronize the heading bug on all of the large
dis-
plays to the current airplane heading as read under the lubber fine on
the pilot's
PFD .
The joystick is used
to
position
the cursor on the MFD . The joystick may
also be used to scroll through MFD page data,
or to select an FMS
way-
point on the MFD map display .
