CREW STATION

The Crew Station (1) is a full-sized model of the BFV Commander and Gunner Stations (see TM 9-2350-252-10-2). The

Loader's and Driver's Stations are not simulated. Vehicle and weapon sounds are simulated and heard through the CVC

helmets (2). The noises and sounds that are simulated are hits on ownvehicle, 25mm gun firing, TOW firing, 7.62mm

coax firing, smoke grenade firing, enemy fire and friendly fire. Other BFV sounds included are Night Vision System

cooling, gun exhaust fan, crew ventilation fan, and engine and transmission noises, including idle and tread clutter at

various speeds. The intercom and simulated radio system also serves as a direct link between the Commander, Gunner

and the Instructor/Operator. Ownvehicle movement is simulated and modified by movement of the normal sight scenes.

Ownvehicle movement can be stopped and restarted by the Instructor/Operator. The 25mm gun recoil is simulated

through the browpads (3) of the sights. The vehicle Commander's and Gunner's sights that are simulated are the ISU (4)

the ISUW (5) the CR (6), the CFP (7) and the Auxiliary Sight Unit (ASU) (8).

The BFV Gunner's sight scenes are viewed in the ISU, ISUW and ASU. The BFV Commander's sight scenes are viewed

in the CR CFP and the ASU. The ISU, CR and Auxiliary sight scenes, as viewed by the Gunner and Commander, are

displayed by the same display equipment. Four in-use sensors (9) detect which sight is being used by the crew.

WARNING

Do not look straight into the in-use sensors (9) when the

eye is closer than 4 inches to the sensor. The sensors

emit infrared radiation and can cause serious damage to

eyesight.

When the crewman's head is moved close to the sight, the in-use sensor is turned on. The two in-use sensors for the

Gunner's Station are mounted near the ISU and the ASU sights. When the Gunner moves his head to the ISU or ASU, a

sensor is turned on. The GPC switches the scene to the sight the Gunner is using. When the Gunner is not using the

ISU or the ASU, both in-use sensors are off, and the sight scene is shown on the ISUW. The two in-use sensors for the

Commander's Station are mounted near the CR and the ASU. When the commander moves his head to the CR or ASU,

a sensor is turned on. The GPC switches the scene to the sight the Commander is using. When the Commander is not

using the CR or the ASU, both in-use sensors are off and the sight scene is shown on the CFP.

The 25mm Gun and turret pointing controls simulate those in the BFV. Each Power Control Handle and its manual

backup system simulates the force, movement and resulting weapon system responses as in the BFV equipment. All

palm switches, trigger switches, and manual firing handles are functionally simulated. Manual controls are blocked when

in the powered or stabilized mode. Traverse and elevation are simulated by visual scene movement in the sights.
