a. CUE Update Procedure.
NOTE
The CUE update procedure should be accomplished
whenever the TADS FLIR is
reportedas being unable to be internally
boresighted. Once the CUE update
procedure has been accomplished and
the TADS FLIR still cannot be boresighted,
continue with troubleshooting
as specified in TM 9-1270-476-20.

tracking gates capture laser spot. Continue
to fire the laser until tracking gates
disappear. If spot cannot be captured by

c. TADS Outfront Boresight.
TADS Outfront Boresight validation
and adjustment (if necessary) shall
be performed prior to using the TADS
FLIR imagery for laser or weapons
operations, after performing a cue
update, a TADS component change or
if the helicopter experiences an abnormal
electrical shutdown.
1. Position helicopter on the ground over identified
location for this procedure.
2. If on an approved laser firing range, fire laser
to obtain range. Otherwise, enter manually
the range from helicopter to the outfront boresight
target.
NOTE
If the target is between 0.5 km and
1.5 km, the range entered on the DEK
must be within 10 meters. If the target is
between 1.5 km and 5 km, the range entered
on the DEK must be within 50 meters.
If the target is greater than 5 km, the
range entered on the DEK must be within
1 km.
3. Observe the outfront boresight target in
NFOV FLIR, adjust gain and level for optimum
autotracker image. Engage LAT.
