Radar Operation
2.3.6 Issued 4/95 SW 06/07/08/11
Beginning with EFS software ver-
sion 11, a Split Screen mode is
added to the VP button selection
sequence immediately following
the Vertical Profile mode. Durng
this Split Screen mode the EFS
will toggle the antenna between
vertical and horizontal scans
every 6 seconds, allowing both to
be displayed simultaneously on
the MFD. See Figure 4.4.4.
Note: This Split Screen mode is
an operational enhancement
added to EFS 11 software that
does not require any modification
to
the existing RDS
82VP/84VP/86VP weather sys-
tems. Since this feature was not
part of the original design of
these radars, the transition
between horizontal and vertical
scans is not synchronized to the
antenna scan and will therefore
occur at random scan positions.
Horizontal (azimuth) and vertical
(tilt) track lines are displayed on
the MFD full time during the split
screen mode to indicate the
antenna scan position in each
plane.
TRK
❏ (Optional) If the weather only
mode is selected on the MFD,
pressing the TRK button acti-
vates and slews a yellow dashed
azimuth line. It also activates a
digital display showing the num-
ber of degrees the azimuth line is
located left or right from the nose
of the aircraft. In any other map
weather presentation, only the
yellow dashed line will be dis-
played.
For VP operations, the TRK but-
ton performs two functions. 1.)
Prior to engaging VP, the appro-
priate button (left or right) is used
to place the track line at the
desired azimuth angle to be verti-
cally scanned (sliced). When VP
is engaged, the slice will be taken
at the last position of the track
line, whether it is visible or not. If
the track line has not been
selected after power has been
applied to system and VP is
engaged, the slice will be taken
at 0 degrees (directly in front of
the aircraft). 2.) When in VP
mode, pressing the TRK will
change the selected azimuth
two-degrees left or right, depend-
ing on which button is pressed.
Continuously holding the TRK
button will result in the system
“slicing” in two-degree incre-
ments.
