Symmetrical Ground Returns; Stabilization In Straight And Level Flight Check Procedure - Honeywell PRIMUS 660 Pilot's Manual

LEVEL FLIGHT STABILIZATION CHECK
Check stabilization in level flight using the procedure in table 5–3.
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 until a band of ground returns
starts at the 40 NM range arc.
4 After several antenna sweeps, verify that ground
returns are equally displayed (figure 5–18). 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.
