BendixKing SG 465 System EFS 50 - Manual (Page 86)

EHSI Displays
4.1.20 Issued 4/95 SW 06/07/08/11
The expanded sectored (ARC)
format provides an enlarged dis-
play of weather radar information
and increased resolution of navi-
gation data due to the enlarged
compass scale presentations.
Note: The following will ad-
dress only those areas of the
EFS 50 ARC mode which are
different from the standard
EHSI compass or MAP pre-
sentations.
HDG BUG (ALL ARC
FORMAT MODES)
Heading bug operation is the
same in all modes. The only
noticeable difference in the ARC
mode is that the digital orange
readout of selected heading is
displayed only when the heading
bug is not completely in view. In
this event the heading readout
appears on the side of the com-
pass scale closer to the heading
bug’s hidden position.
COURSE DEVIATION
INDICATOR (EHSI ARC
NON-MAP FORMAT)
The rotating white course devia-
tion scale operates the same in
all non-map modes. The differ-
ences in the ARC modes are
location and size: the scale is
moved to the bottom center of
the display and is slightly
reduced in size.
The displays covered in this sec-
tion are custom displays, created
at the request of specific cus-
tomers to satisfy unique require-
ments. Every attempt was made
to ensure these displays followed
standard EFS 50 colors, symbol-
ogy and methodology. In some
cases this was not possible, it is
therefore, most important to read
the following information and
ensure you have a very good
understanding of the display and
its intended use. If there are any
questions concerning the follow-
ing displays, contact the installing
agency or a Bendix/King factory
representative for additional infor-
mation.
