The ONEAG are self-contained, helmet-mounted, passive night vision goggles that enable pilots to fly in terrain flight modes at night. The system amplifies ambient light from natural sources such as the Moon, the stars and the sky glow, so that the observed scene becomes clearly visible to the operator.

The ONEAG has the following convenient features: powered by batteries and on-board power source; low-battery indicators on the helmet mount and power pack lights, if the battery level is low; eye span; vertical distance; tilt; eye relief; diopter adjustment.
