Symbology Development for a 3D Conformal Synthetic Vision Helmet-Mounted Display for Helicopter Operations in Degraded Visual Environment

To increase situation awareness for helicopter pilots in poor visibility symbology for a helmet-mounted display was developed. The symbology comprises the conformal presentation of obstacles, route information and threat areas. In an online survey 48 helicopter pilots evaluated the designs from a user-centered perspective and provided comments and suggestions of improvement. The paper presents selected results of the survey and discusses general aspects associated with the use of conformal symbology and helmet-mounted displays.
