SYMBOLIC AIRCRAFT
The orange symbolic aircraft pro-
vides a visual reference of the
aircraft present position in rela-
tionship to the deviation bar.
HEADING SELECT “BUG”
A notched orange heading bug is
manually rotated around the
compass scale by the heading
select knob on the control panel.
In the 360-degree compass
mode a full time digital readout of
the selected heading is displayed
below the vertical deviation scale
position. In the ARC mode, a
digital heading readout is dis-
played when the heading bug is
not completely in view. The digi-
tal readout will be positioned just
inside the compass scale on the
side nearest the heading bug.
Once set, the heading bug
rotates with the compass card.
The heading bug is used to indi-
cate desired heading and pro-
vides selected heading reference
for autopilot steering.
A RED X will be drawn through
the heading bug if there is a
heading select knob failure on
the EFS 50 control panel.
COURSE SELECT
The CRS control knob rotates the
course pointer about the com-
pass scale and sets digital
course readout. Once set, the
course pointer rotates with the
compass card. The selected
course indicates desired naviga-
tion course to be flown. Depend-
ing on the LNAV (long range nav-
igation) installed, the course
pointer may automatically be
positioned to the DTK (desired
track) when LNAV is selected as
the primary sensor. When LNAV
is the selected sensor and DTK
is displayed, the EFS 50 course
select knob is disabled.
In the upper left corner of the dis-
play, an alphanumeric readout
annunciates the letters CRS and
