4.33 ARMAMENT INFLIGHT PROCEDURES.
4.33.1 30mm Gun System.
If 300 or more rounds have been fired
in the preceding ten minutes, and a
stoppage occurs, personnel must remain
clear of the aircraft for 30 minutes.
Aircraft crewmembers should
remain in the aircraft and continue
positive gun control.
1. CPG ARM/SAFE switches - ARM.
2. GUN select switch - As desired.
3. Crewmember desiring to fire - Establish
range to target and track target with selected
sight.
4. WAS switch - GUN.
5. Weapons trigger - Press, continue to fire as
required.
6. WAS - Deselect GUN.
4.33.2 AWS Harmonization Procedures
1. Locate target approximately 1000 meters
(± 50) from aircraft position.
2. Hover aircraft 100 FT (± 20) above target altitude
and maintain heading (± 5°) azimuth.
3. Sensor select switch - TV d.
4.
5.
6.
Field-of-view select switch - N or Z.
LSR select switch - ON. e.
Laser trigger - Press. Ensure the displayed
range to target is accurate to ± 10 meters.
7. Laser trigger - Press. Confirm range.
NOTE
Harmonization burst shall be accomplished
in the narrowest field of view
which the CPG can observe the rounds impact
(wide/narrow).
f.
g.
4-66 Change 4
8. Field-of-view select switch - W or N.
NOTE
A video recording may be used to verify
impact area.
9. Fire one or two 10 round bursts. Note centroid
of impact area.
10. Determine the appropriate sector from the appropriate
field of view Corrector Guides (figs
4-19.1 and 4-19.2) for harmonization offset
values.
NOTE
l A fraction of the offset values in a sector
can be used to improve accuracy
l Go to step 12 to enter modified
correctors.
11. For enter modified correctors:
a. DEK switch - SP1.
b. Enter G on the DEK.
C. The screen will display harmonization
corrector Deltas and Totals in the following
format:
AWS HARMONIZATION
DELTAS -MRAZ=+
00.0 EL=+00.0
TOTALS -MRAZ=+
00.0 EL=+00.0
On the DEK enter 1 to access azimuth or 2
to access elevation corrector value(s) to be
changed.
Enter corrector Delta value(s) from the
Corrector Guides (figs 4-19.1 and 4-19.2).
Repeat steps 1 through 11 while reducing
field of view as appropriate to DTV-NFOV
until center of impact is verified to be
within zoom FOV gates. When FOV gates
are achieved, proceed to step g.
DEK ENTER button - Press. This will
complete the modification.
