Radar Operation
Beginning with EFS software ver-
sion 09, a Split Screen mode is
added to the VP button selection
sequence immediately following
the Vertical Profile mode. During
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 09 software that
does not require any modifica -
tion to the ex is ting RDS
82VP/84VP/86VP/RDR 2000
weather radar systems. Since
this feature was not part of the
original design of these radars,
the transition between horizon -
tal 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
p l a n e .
TRK
o
(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, called continuous profile.
Continuous profile is not used on
the RDR 2 0 0 0 .
Beginning with EFS software ver-
sion 09, the Drift Angle Track fea-
ture can be activated on the MFD
by pressing both TRK buttons
simultaneously. While active, this
feature places the track line at
the drift angle provided by an
LNAV. The track line always indi-
cates the azimuth angle at which
a vertical scan is performed for
VP operation.
Note:Approximately 15 seconds
after drift angle track is select -
