Radar Operation
vates gain control. “MAP” will be
displayed below the NAV source
annunciator on the radar mode
line. (Magenta is not active in the
GND MAP mode.)
LIGHTNING
o
(Optional) Enables the Light-
ning display when pressed if a
weather mode is selected for dis-
p l a y .
VP
o
(Optional) Once the desired
azimuth is selected with the TRK
button, press the VP button to
enter the Vertical Profile mode of
operation. The Vertical Profile
Screen will appear. The weather
mode of operation (WX, WXA or
GND MAP) displayed in the
lower left corner of the display
will be the same as existed just
prior to selecting VP. To select a
different weather mode once in
Vertical Profile, simply select the
desired mode (WX, WXA or GND
MAP) by pressing the appropri-
ate button.
Note: A brief period of time will
normally elapse before the dis -
play will “paint” the Vertical
Profile “picture”. This time
delay is due to the fact that the
radar continues its nor mal
azimuth scan after the VP but -
ton is pressed.
The operation of scanning the
antenna vertically (+/- 20 or +/-
30 degrees depending on the
Radar) is referred to as taking a
vertical “slice”.
Once Vertical Profile is selected,
the desired profile-azimuth angle
may be changed in two degree
increments by pressing and hold-
ing the appropriate TRK button.
One of two things will happen
when a TRK button is pressed:
(1) If the radar
’ s antenna is
already profiling, the antenna will
move in the two-degree incre-
ments, “slicing” in the direction
determined by the TRK button; or
(2) A “WAIT” annunciation will be
displayed indicating that the
radar
’ s antenna will perform the
desired “slicing” function as soon
as the antenna returns to the last
selected profiling-azimuth angle.
Depending on the software ver-
sion of the RDS VP radar and
the system installation, the anten-
na may also scan horizontally
while in the VP mode. If the
antenna is not sweeping vertical-
ly when the TRK button is
pressed, a “WAIT” annunciation
will be displayed until the anten-
na returns to the last vertical
“slice” azimuth.
To terminate the Vertical Profile
mode and return to the normal
mode (horizontal scan), press the
VP button. The radar system will
retain its existing weather mode
and return to horizontal scanning.
A track line will be present on the
screen for 15 seconds to indicate
the location of the last profiling-
azimuth angle.
