of Multi-function Control and Display Unit (MCDU) #3. The panels are
illustrated in Figure 20. The left (pilot) control panel / controller is powered
by the left main DC bus, the right panel / controller (copilot) by the right
main DC bus. Each panel selects the functions of the respective radar
controller that is interfaced with all three (3) Modular Avionics Units (MAUs)
to communicate operational settings to the RTA and to select display range
settings on both the MAP and PFD displays.
WARNING
PRIOR TO OPERATING THE RADAR ON THE
GROUND, ENSURE THAT NO PERSONNEL ARE
WITHIN FORTY NINE (49) FEET OR FIFTEEN (15)
METERS OF THE FRONT OF THE AIRCRAFT.
ALSO DO NOT OPERATE THE RADAR WHILE
REFUELING THE AIRCRAFT OR WITHIN THREE
HUNDRED (300) FEET OR NINETY-TWO (92)
METERS OF OTHER REFUELING OPERATIONS.
Each control panel has the following features for selecting the RTA
operational mode and desired display presentation. An annunciator box is
shown in the left bottom corner of the windows containing the radar display.
The box provides an indication of the current radar operating mode and/or
antenna tilt setting.
(1) MODE rotary knob with the following settings:
•
OFF - prevents power to the RTA
•
STBY - selects standby mode to power the RTA assembly
without antenna movement or signal transmission
•
TEST - to perform a system test with the antenna transmitting
and a test pattern shown at a one hundred (100) mile range.
Faults discovered during the test will be annunciated on the
selected radar display.
NOTE:
The TEST mode powers the RTA transmitter. Observe
the distance standoffs cited in the WARNING shown
above.
•
WX - selects the weather radar operational mode to detect
radar returns from precipitation
•
GMAP - selects the ground mapping mode to detect terrain
features with the weather radar. The antenna down tilt will be
automatically determined by the display range selected (tilt
may be manually set if desired).
NOTE:
Precipitation areas are not calibrated (depicted in
colors corresponding to intensity) when the radar is in
ground mapping mode. The mode should not be used
for weather detection or avoidance.
