Stabilization Precheck
Prior to performing any of the adjustment procedures, conduct the
precheck procedures listed in tables 5-5 and 5-6.
LEVEL FLIGHT STABILIZATION CHECK
Check stabilization in level flight using the procedure in table 5-5.
Step Procedure
1 Trim the aircraft for straight and level flight in smooth,
clear air over level terrain.
2 Select the 50-mile range.
3 Rotate the tilt control upward until all ground returns
disappear.
4 Rotate the tilt downward until ground returns just begin
to show.
5 After several antenna sweeps, verify that ground
returns are equally displayed (figure 5-19). If returns
are only on one side of the radar screen or uneven
across the radar screen, a misalignment of the radar
antenna mounting is indicated. This problem can be
corrected by means of the roll offset function before
proceeding (figures 5-20 and 5-21).
6 Refer to the roll offset adjustment procedure in table
5-7.
