Stabilization Precheck; Stabilization In Straight And Level Flight Check Procedure - Honeywell Primus 880 Pilot's Manual

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
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.
