RCT (Rain Echo Attenuation Compensation Technique
(REACT))
The RCT switch is an alternate- action switch that enables and
disables REACT.
The REACT circuitry compensates for attenuation of the radar signal
The REACT circuitry compensates for attenuation of the radar signal
as it passes through rainfall. The cyan field indicates areas where
further compensation is not possible. Any target detected within
the cyan field cannot be calibrated and should be considered
dangerous. All targets in the cyan field are displayed as fourth level
precipitation, magenta.
REACT is available in the WX mode only and selecting REACT forces
REACT is available in the WX mode only and selecting REACT forces
the system to preset gain. When engaged, the white RCT legend is
displayed in the REACT field.

NOTES:
1. REACT’S
three
main
functions
(attenuation
compensation, cyan field, and forcing targets to
magenta) are switched on and off with the RCT switch.
2. Refer to Section 5, Radar Facts, for a description of
REACT.

STB (Stabilization)
The STB button toggles pitch and roll stabilization ON and OFF. It is also
used with the STB adjust mode and to override forced standby.
The radar antenna is normally attitude stabilized. It automatically
The radar antenna is normally attitude stabilized. It automatically
compensates for roll and pitch maneuvers (refer to Section 5, Radar
Facts, for a description of stabilization). The STB OFF annunciator is
displayed on the screen.
