3 STB (Stabilization)
The STAB button is a that turns the pitch and roll stabilization ON and
OFF.
This radar is normally attitude stabilized. It automatically compensates
for roll and pitch maneuvers (refer to Section 5, Radar Facts, for a
description of stabilization). The amber STB annunciator appears
on the screen. It is also used with the STB adjust mode, and to override
forced standby.
4 RCT (Rain Echo Attenuation Compensation Technique)
Selecting RCT forces the system to preset gain. When RCT is selected,
the green REACT legend is displayed in the mode field. The RCT
circuitry compensates for attenuation of the radar signal as it passes
through rainfall.
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.
NOTE: Refer to Section 5, Radar Facts, for a description of REACT.
