Operational Controls
2
GAIN - The gain knob adjusts the radar gain from 0 to
-20 dB (CCW rotation reduces gain). The gain knob will
only function when in the MAP mode.
LOG - Used when Bendix/King radar graphics units are installed. A
listing of the latitudes and longitudes of selected waypoints are dis-
played. When a compatible navigation source is installed, the selected
VOR frequencies along with bearings and distances are also displayed.
The radar transmits in the LOG mode, unless a Bendix/King radar
graphics unit (IU-2023, GC-360A or GC-381A) is installed.
ON - Selects the normal condition of operation for
weather detection and/or other modes of opera-
tion. The system will transmit after a 60 second
warm-up time is completed. The radar system ini-
tializes to the Wx mode, 80 nm.
Note: The 60 second warm up period can be monitored upon power up
of the system. When the knob is switched directly from OFF to ON mode
(or LOG mode with no Bendix/King radar graphics unit installed), the dis-
play will blank. As the radar sweeps the blue/white will grow outward.
Just before the warm up period is complete, the screen will turn black for
a few seconds, then the radar will begin transmitting and the screen will
display radar returns. No radar transmissions occur until the warm up
period is complete.
TST - The multicolored arc display test pattern is displayed in this mode
of operation. The test pattern (typical 4-color test pattern on page 4) is
initialized and sized to fit the 80 nm range and can also be scaled with
the range select buttons. No radar transmissions occur while TST is
selected. TEST will appear in the lower left of the display.
STAB OFF is always displayed in top left.
SBY - Fully energizes the system circuitry but no radar transmissions occur
in the SBY mode of operation. The antenna is parked at 0 degrees azimuth
and 30 degrees tilt down with the antenna drive motors locked. In the
standby mode of operation, NAV MAP, checklist and TCAS traffic can be
activated with a Bendix/King radar graphics unit (IU-2023B, GC-360A,
GC-362A or GC-381A) installed. SBY will appear in the lower left of the dis-
play.
