WEATHER RADAR (X
0
BAND)
(TYPE RDR-160)
PILOT'S OPERATING HANDBOOK
SUPPLEMENT
EXTENDING LIFE OF THE MAGNETRON TRANSMITTING TUBE:
1.
The RDR-160 weather radar system is designed so that full
operation is possible approximately two minutes after turn on.
Therefore, the pilot may choose to leave the function switch in OFF
rather than STBY if no significant weather is in the immediate area
of the aircraft. The life of the magnetron transmitting tube will be
extended by leaving the system "OFF" when possible. This in turn
will reduce the cost of
maintenance.
NORMAL OPERATION
WEATHER DETECTION:
1.
Function Switch -- 80 position (allow 2 minutes warm-up)
.
2.
Mode Selector Switch -- SELECT as desired:
Wx - Weather.
WxA - Weather
Alert.
3.
BRT Switch -- ADJUST as required for ambient light conditions.
4.
Antenna Tilt Control --
+4°
to +6° (approximate minimum angle
relative to horizon without ground return).
NOTE
If airplane is climbing or descending, tilt angles must be
reduced or increased by approximately the pitch angle
indicated on the attitude
gyro.
5.
Function Switch -- SELECT desired range.
6.
HOLD Switch -- ENGAGE if desired to "freeze" display on indica-
tor to track storm movements.
7.
Aircraft -- MAINTAIN SPEED and HEADING to assure an accu-
rate picture of relative motion of storm in next
step.
8.
HOLD Switch -- DISENGAGE HOLD switch to compute storm
movement and return antenna to scan mode.

GROUND MAPPING:
8
NOTE
Ground mapping is a secondary feature of this radar which
is only useful after the operator is very familiar with this
equipment. More complete discussion of this feature is
included in the RDR-160 Pilot's Manual.
1.
Function Switch -- SELECT DESIRED RANGE (allow 2 minutes
warmup).
