WX -- This position selects the weather mode. In the weather mode
D
the system is fully operational and WX is displayed in the mode field.
If WX is selected before the initial RTA warmup period is over, WAIT
is displayed in the mode field. In the wait mode, the transmitter and
antenna scan are inhibited and the display memory is erased. When
the warmup is complete, the system automatically switches to the
weather mode. In the weather mode, with the system is in preset
gain, precipitation is displayed as described in Table C--2.

RCT -- This positions turns the RCT (Rain Echo Attenuation
D
Compensation Technique) circuitry on. RCT is a submode of the
weather detection mode. Selecting RCT puts the system in preset
gain and RCT is displayed on the EFIS or MFD.
The REACT circuitry compensates for attenuation of the radar
signal as it passes through rainfall. The
where further compensation is not possible. Any target detected
within the cyan
dangerous. All targets in the
fourth level precipitation.
GMAP -- This position puts the radar in the ground mapping mode.
D
In the ground mapping mode the system is fully operational and
GMAP is displayed in the mode field.
