Because of this accident, a modified faceplate (MFP) for NVG was configured to allow pilots unaided lateral and lower vision. Twenty MFP NVG were worn during flight by 47 NVG qualified aviators for an average of 18 hours per aviator. The average recorded flight hours for each of the 20 MFG NVG was 43.5 hours. NVG aviators indicated that the MFP significantly enhanced intruder aircraft detection, inside-the-cockpit vision, and comfort. Spectacles can be worn with the MFP, and less fogging of the eyepieces occur. There were deficiencies reported during the study which were corrected with modifications to the mounting apparatus, thorough preflight briefings, and required familiarization flights. The proposed modification is being considered for adoption by the proper authorities. (Author) 收起
