NIGHT VISION GOGGLE DRIVING OPERATIONSWhat are Night Vision Goggles

NVG VGT-09

Night Vision Goggles are devices that make an object more visible during periods of low light levels. Their performance is directly related to the amount of light available, such as starlight and moonlight.

NIGHT VISION GOGGLE DRIVING OPERATIONSAdvantages

NVG VGT-10

Better view of the surrounding area and object identification at night

NVGs make it possible to:ReadPatrolProvide medical aidDriveWalkObserve the enemy

At night without the

help of lights

NIGHT VISION GOGGLE DRIVING OPERATIONSDisadvantages

NVG VGT-11

Performance is reduced in rain, haze, fog, snow or smoke.Visual acuity is reduced.Limited field of view.Reduced depth perception.Overconfidence.Focal range.

NIGHT VISION GOGGLE DRIVING OPERATIONSDriving With The NVG

NVG VGT-20

Phase I:Drive a vehicle on a designated route in DAYLIGHT conditions.

Phase II:Drive a vehicle on a designated route at night with vehicle headlightson (without NVGs).

Phase III:• Perform pre-operational NVG procedures.• Perform vehicle PMCS (before OP) while wearing NVG.• Drive a designated route at night with NVGs.• Identify signs, route markings, ditches, etc.• Perform post-operational NVG procedures.• Perform vehicle PMCS (after OP) while wearing NVGs.
