MIL-T-62222(AT)
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
