Entering a Desired Course
The
VXA-300
can also be configured to indicate the de-
viation from the desired course, not only the deviation from
the path to the VOR station.
Set the frequency to the desired VOR station.
Change the “
” or “
” flag to “
,” if it is not
in that mode already.
Press [
F
] à [

(
CDI
)] key to change to the CDI mode.
Set the desired course to the VOR station using the
DIAL
selector knob or keypad (three digits are re-
quired; e.g. for 47°, press [

[

[

Note 1
: The (“
”) or (“
”) indication will
appear on the display when your aircraft is off the de-
sired course.
Note 2
: When your heading is correct, the ABCS func-
tion may be more useful than the course input option
The Course Deviation Arrow points to the right when
your aircraft is off course to the left, and it points to
the left when your aircraft is off course to the right.
ABCS Mode
In the CDI mode, the Auto Bearing Center System
(ABCS) adds or subtracts the number of degrees indi-
cated by the CDI from the Omni Bearing Selector
(OBS).
Note 1
: To get back on course, fly right more than the
number of degrees indicated by the Course Deviation Ar-
row.
Note 2
: If the overflow indicator “
” appears on the right
side, select a heading plus 10 degrees to the desired course;
if the overflow indicator “
” appears on the left side, se-
lect a heading minus 10 degrees.
