PITCH OFFSET ADJUSTMENT
This in–flight adjustment is made in straight and level flight when the
ground returns do not follow the contours of the radar display range
arcs. The procedure is listed in table 7–4.
Step Procedure
1 If two controllers are installed, one must be turned off.
If an indicator is used, the procedure is the same as given
below.
2 Fly to an altitude of 10,000 feet AGL or greater.
3 Set range to 50 NM.
4 Adjust the tilt down until a solid band of ground returns are
shown on the screen. Then adjust the tilt until the green
region of the ground returns start at about 40 NM.
5 Select STAB (STB) 4 times within 3 seconds. The roll
offset display is shown.
6 From the roll offset entry menu, push the STAB (STB)
button once more to bring up the pitch offset entry menu.
7 To change the pitch offset value, pull out the GAIN knob
and rotate it. The offset range is from –2.0
°
to +2.0
°
.
8 When flying straight and level, adjust so the contour of the
ground returns follow the contour of the range arcs as
closely as possible.
