4.6.17.3.4.1.2 Turret traverse speeds. To determine conformance to 3.5.3.4.1.2, the turret
shall be tested for controllability over speed ranges specified. Tests shall be conducted with
gunner's and commander's power controls, and in both directions of turret rotation. The
accumulator shall be fully charged prior to maximum traverse speed tests. Maximum speeds
shall be checked by allowing the turret to accelerate approximately 400 mils from stop and
observing the time required to complete the next 3200 mils (1/2 revolution) of traverse. Tests for
gunner's handle displacement shall be conducted in both directions of rotation.
4.6.17.3.4.2 Main gun laying tracking.
4.6.17.3.4.2.1 Gun laying (stationary target and vehicle). To determine conformance to
3.5.3.4.2.1, tests shall be performed in accordance with the following:
a. Tests shall be conducted with the gunner's controls and repeated with the
commander's controls. Tests with the manual controls shall be conducted from the
gunner's position only.
b. For testing, the sighting on the specification target shall be performed for positions 3,
5 and 7 of table IV. Two trials shall be made and the average time shall be used for
determination of compliance.
4.6.17.3.4.2.2 Gun laying on moving target and tracking accuracy. To determine
conformance to 3.5.4.2.2, tests shall be conducted in accordance with the following:
a. Tests with the gunner's and commander's controls shall be conducted with the
vehicle operating in the power mode. A suitable turret tracking instrument with
timer, recorder and calibrating device shall be used for performing tests. Tests shall
be conducted in both clockwise and counterclockwise directions.
b. For testing, the traverse rates of 0.5, 3.3, 32.6 and 65.2 mils per second as shown in
table V shall be used.
4.6.17.3.4.3 Operation on slopes. To determine conformance to 3.5.3.4.3, tests shall be
conducted in accordance with the following:
a. The vehicle shall be located on a 15 + 2 degrees slope for laying on target as specified
in table IV. Tests shall be conducted in power mode with gunner's controls and
repeated with the commander's controls. Manual control tests shall be performed at
gunner's station.
b. For testing, the sighting on the specified target shall be accomplished for positions 3,
5 and 7 for power mode and for 3 and 5 for manual mode of table V. One
determination shall be made for each of the positions specified.
