The Federal Aviation Administration (FAA) has requested human factors guidance to support the new moving map Technical Standard Order (TSO)-C165, Electronic Map Display Equipment for Graphical Depiction of Aircraft Position. This document was developed to meet that need and is intended to facilitate the identification and resolution of flight-deck human-factors issues associated with presenting an airport surface moving map that depicts ownship location. The guidance in this document contains FAA regulations, industry documents, and user interface design principles that describe good practices relevant to the design of surface moving map displays. This document applies to all surface moving map displays regardless of the display platform. Topics in this document cover general user interface issues, the design of surface moving map display elements, the presentation of traffic, and the usability of functions. Additionally, an industry review describing the efforts by manufacturers and research organizations to develop a moving map display with ownship position is provided in Appendix A, and a summary of guidance is included in Appendix B.
