ROLL OFFSET ADJUSTMENT
You can make an in–flight adjustment when level flight stabilization
errors are detected. This procedure is done by either the WC–660
Weather Radar Controller or the WI–650/660 Weather Radar Indicator.
During this procedure, described in table 7–3, the GAIN control acts as
roll offset control. After the procedure the GAIN control reverts to acting
as a gain control.
Step Procedure
1 If two controllers are installed, one must be turned off.
If an indicator is used as the controller, the procedure is
the same as given below.
2 Fly to an altitude of 10,000 feet above ground level (AGL),
or greater.
3 Set range to 50 NM.
