K. AUTOMATIC TADS GYRO ALIGNMENT.
This procedure is used for automatically
aligning the gyros. The TADS inertial axis is
aligned with the optical axis to eliminate po-
tential pitch and yaw disturbances. This task
is to be performed after replacement of the
TEU, DSA roll/pitch/yaw gyros and the
1. FOV N.
2. TADS TV.
3. SLAVE switch SLAVE to bring TADS turret out
of fixed forward position. 49 Set DEK-FD/LS
then press mid shift key and enter B32. 51
CDU FAD-FDLS then type B32 in the
4. SLAVE switch Unslave.
Shortly after ALIGNMENT IN PROG-
RESS message appears, the TADS turret
will begin vertical and lateral motions,
then stop. System will enter manual track
mode when bite target appears on dis-
play. The bite target is displayed by a
white rectangle above the letters PR of
the ALIGNMENT IN PROGRESS mes-
sage. The presence of the white rectan-
gle indicates the system is waiting for the
next portion of the alignment procedure.
Pitch and yaw gyro alignment is normally
performed airborne, but may be per-
formed on the ground if a suitable target
is available. The target is required to be
at an up or down elevation greater than
25 degrees from zero.
