3.5.3.4.3 Operation on slopes. When the vehicle is canted or pitched on slopes up to and
including 15 degree turret attitude, the control system shall be capable of gun laying on a
0.25 mil stationary target as specified in 3.5.3.4.2.1, except time limitation need not be met.
Turret chatter shall be allowed only when turret unbalance tends to cause turret rotation in the
same direction of manual traverse. The gun control system performance on level terrain shall not
be affected in any manner as a result of vehicle operation on slopes. A combat load of simulated
equipment may be employed if desired (see 4.6.17.3.4.3).
3.5.3.4.4 Stability of operation. With the vehicle level or on slopes up to a 15 degree turret
attitude, and turret power activated or deactivated, the gun shall not move more than 0.5 mil in
azimuth or elevation during a one hour period (see 4.6.17.3.4.4 and 4.6.17.3.4.4.1).
3.5.3.4.5 Traverse and elevation limits. The angular main gun movement from the
horizontal position shall be in accordance with the following requirements (see 4.6.17.3.4.5):
a. 19 degree minimum elevation for 360 degrees of turret traverse by power and manual
controls.
b. 8 degree minimum depression each side of vehicle front centerline to 95 degrees
maximum of rear vehicle centerline by power and manual controls.
c. 5 degree minimum depression from 95 degrees each side of vehicle rear centerline to
28 degrees each side of vehicle rear centerline by manual control with elevation and
traverse power switch off.
d. 0 degree minimum depression 28 degrees each side of vehicle rear centerline by
manual control with elevation and traverse power switch off.
e. 0 degree minimum depression 95 degrees each side of vehicle rear centerline by
power and manual controls with elevation and traverse power switch on.
3.5.3.4.6 Override control. The commander's control shall take over instaneously the power
control of the turret and gun and the firing circuits from the gunner's control when the override
switch in the commander's control handle is actuated. Override of the system control by the
commander's control shall be obtainable at the neutral position regardless of the handle position
of the gunner's control. With the commander's control and gunner's control in the neutral
position, there shall be no movement of the gun or turret caused by depressing or releasing the
override switch in the commander's control handle. With the gunner's control in the neutral
position, the gunner's control shall regain system control instantaneously when the commander's
control handle is released (see 4.6.17.3.4.6).
3.5.3.4.7 Hydraulic pressure limit switch. When power traversing the turret at a rate not to
exceed 65 mils per second, the hydraulic pressure switch shall activate the hydraulic control
power pack motor at a control system pressure gage reading of 880 to 1010 psi. With the
gunner's and commander's power and manual controls in neutral position, the hydraulic pressure
