Regulatory Requirements for Certification of Head-Up-Displays with an Emphasis on Human Factors

Head-up displays (HUD) is a flight instrument that display head up information, superimposed over the outside scene. Human factors evaluation concerns human beings and their characteristics, which is strongly related to equipment function and operational environment. This paper reviews key points of HUD design and extracts the human factors dimensions for HUD human factors certification. The following discussion for each evaluation point is focused on the related regulations identified in the HUD human factors certification plan, proposed method of compliance (MOC), and factors for certification associated to the state of operational use of HUD. This paper is only a draft guide for HUD human factors certification, which will be updated with the development of new technologies of HUD.
