BendixKing SG 465 System EFS 50 - Manual (Page 45)

EHSI Operation
2.1.10 Issued 4/95 SW 06/07/08/11
COURSE SELECT KNOB
Rotation of the COURSE
SELECT knob allows the course
pointer and digital course to be
set at the desired course.
The CP467 and CP468 provide
a ”DIRECT TO” feature. Pulling
the CP467 or CP468 COURSE
SELECT knob will cause the
course pointer and digital course
read out on the EHSI to slew to
the direct course to the selected
NAVAID.
If the selected NAV sensor is an
LNAV system, it may have
modes of operation that control
the selected course.
During these LNAV modes of
operation the EFS 50 COURSE
SELECT knob will be inactive.
HEADING SELECT KNOB
Rotation of the HEADING
SELECT knob allows the head-
ing bug on the EHSI to be rotated
to the desired heading.
The CP467 and CP468 provide
a “HEADING SYNC” feature.
Pulling the CP467 or CP468
HEADING SELECT knob will
cause the heading bug on the
EHSI to slew to the present air-
craft heading (lubber line).
DISPLAY BRIGHTNESS
CONTROL
The BRT knob controls the dis-
play brightness.
Note: The display brightness
control provides full range dim-
ming to allow night operation
in no- or low-light situations.
The lower limit of the display
brightness may appear as an
inoperative tube during normal
daylight operation. It is there-
fore advisable to check the
BRT knob setting during pre-
flight test.
To ensure maximum display
tube life, it is highly recom-
mended that the display be
operated at the lowest accept-
able brightness level.
