ABSTRACT
Night Vision Goggles (NVGs) and, in particular, the helmet mounted Aviators Night-Vision-Imaging-System (ANVIS-6), has gained increasing importance and use in night-time military helicopter operations (Brickner, 1989; Ruffner, Grubb, & Hamilton, 1992), This increasing reliance on NVGs to enhance night flying capabilities, particularly at low-level, has also raised several safety concerns (Biberman & Alluisi, 1992).
