CABLE
Refer to Figure 4.1.11 while
reviewing the CABLE DISPLAY.
Incorporated in software 04, the
cable mode, annunciated as
CAB, provides navigation infor-
mation from a cable position sen-
sor. Primary use of this mode is
helicopter related, with the
intended purpose of search and
rescue hover, and heavy lift oper-
ations. The CAB mode is dis-
played on the EHSI as dual con-
centric circles on the compass
card. Cross bars represent cable
angular position left/right and
fore/aft relative to the aircraft..
Only one cable sensor system
may be interfaced to the EFS
40/50 at a time. If more than one
system is interfaced, it will have
to be externally switched into the
E H S I .
Note: The following will address
only those areas of the EFS
40/50 Cable mode which are
different from the standard
EHSI presentations.
w
COMPASS CARD
The map compass card is used
in the CAB mode, the symbolic
aircraft however, is the larger one
used in the normal EHSI mode.
w
ANGLE BARS
Green bars, the length of the
larger circle
’ s diameter, represent
the cable ’ s position angle
left/right component (Px) and
fore/aft component (Py) as refer-
enced to the symbolic aircraft.
The intersection of the two bars
provide the vector sum of the two
position components, or actual
angular position of the cable ref-
erenced to the aircraft.
If the cable sensor information
becomes invalid or failed the
position angle bars will be
removed and a RED X will be
displayed in the center of the
c o m p a s s .
w
FUNNEL SCALE
Two concentric circles inside the
compass card and compass card
azimuth ring itself provide refer-
ence for the cable position angle
bars. A white inner circle repre-
sents 6 degrees of cable deflec-
tion. A yellow circle represents
12 degrees. The compass card
azimuth ring represents 18
degrees of cable displacement.
The symbolic aircraft is one sixth
the size of the compass card;
making it 3 degrees to wing tips,
tail and nose.

WIND VECTOR
I N F O R M A T I O N
If an appropriate LNAV is
installed and is providing valid
information, wind information will
be displayed in its normal loca-
tion. See WIND VECTOR under
STANDARD EHSI DISPLAYS for
additional information.
