IntuVue RDR-4000 Weather Radar Pilot's Guide


For single radar systems (only one radar processing system), place the
System Control Switch in the 1 position to put the system into weather
For dual radar systems (two independent radar processing systems)
place the System Control Switch in either the 1 or 2 position to select
the system to be used. To ensure that both systems are used alternate
between systems on successive flights.
Radar data is then displayed whenever the Display Selection Knob is
set to any radar mode except OFF. When on the ground, the radar will
not transmit if both (CAPT and F/O) Display Selection Knobs are set to
OFF, unless the PWS qualifiers are active (see AUTOMATIC
WINDSHEAR ACTIVATION on pg 18). When in the air the radar scans
continuously, always updating the memory so that current weather is
immediately available. (See also ON/OFF on page 6.)
On initial activation of the radar, or when switched from one system to
the other (1 or 2), the radar first looks at the part of the sky that is near
the aircraft's altitude. This data is displayed as soon as it is available.
As data is gathered from the remainder of the sky in front of the aircraft,
the display quickly fills in with any additional information. It takes no
more than 30 seconds for the complete picture to become available.
Note that when switching from one system to the other, the weather
depicted may not exactly match what was previously displayed due to
the loss of "historical" data from the other system. Therefore, there is
no advantage in switching between systems during flight, except in the
case of the failure of one side.
