This study investigated the impact on near to eye displays on both operational and visual
performance employing a human-in-the-loop simulation of straight-in ILS approaches while
using a near to eye (NTE) display. The approaches were flown in simulated visual and
instrument conditions while using either a binocular NTE or a monocular NTE display on
either the dominant or non dominant eye. The pilot's flight performance, visual acuity, and
ability to detect unsafe conditions on the runway were tested.
