Title:HUMAN ENGINEERING CONSIDERATIONS FOR IMPLEMENTING ENHANCED SYNTHETIC VISION SYSTEMS IN VERTICAL FLIGHT AIRCRAFT
Issuing Committee:G-10v Vertical Flight Committee
Scope: -The scope of this document is limited to Enhanced Synthetic Vision Systems ESVS human factors considerations and requirements in comprehension, interpretation and application of imagery and integrated symbology in Enhanced (sensor) and Synthetic (database) Vision Systems in vertical flight aircraft. Any overlap into logic problems or hardware/software design should be considered to be incidental to the human factors issues. Where the performance characteristics of specific technologies are relevant they will be identified, and where performance criteria are relevant to specific intended functions/use they will be identified. From a regulatory view, intended function (Guidance or Information/Situation Awareness support) has a tremendous effect upon the design of an ESV System. However from a Human Engineering standpoint, the information on display must be discernable and comprehensible to the human operator in both cases and differences may be primarily in information content (required to support a specific task). The document attempts to be independent of candidate technologies and concentrate on human interface criteria. This document does not include consideration of detection and/or display of air targets or integration of systems such as TCAS.
