AVIGATION

To Select the DVOR Mode

When entering the NAV band (108.000 - 117.975
MHz), the 

VXA-300

 selects the DVOR mode auto-

matically. The “

C

OURSE

 I

NDICATOR

” field will appear

at the upper left corner on the display, and the “

”

or “

” indicator will appear below the “Course

Indicator” field on the display.

Note

: The “

C

OURSE

 I

NDICATOR

” indicates “

”

when either your aircraft is too far away from the VOR
station or the frequency is not correctly set to that of
the VOR station. Conversely, the “Course Indicator”
will indicate “

” when receiving a localizer chan-

nel. The 

VXA-300

 cannot decode a localizer signal.

The “

” or “

” flag indicators tell you whether

the VOR navigation information is based on a course
leading to the VOR station or leading away from the
VOR station.

To change the flag from “

” to “

” or vice versa,

press the [

F

] key momentarily, then press the

[

3

 (

FROM

)] or  [

2

 (

TO

)] key, respectively.

The small “

” and “

” flag

indicators may be toggled to the larger “Frequency”
portion of the display. To do this, press and hold in
the [

display area. Press the [

again to return to the smaller displays.
