This industry survey documents the symbols for navigation aids, airports, lines, and linear patterns currently in use by avionics manufacturers and chart providers for depicting aeronautical charting information. Nine avionics display manufacturers and four chart providers participated. The information provided by avionics manufacturers is shown only on electronic displays whereas the information from chart providers is shown on paper charts and may also be shown on electronic displays. The first section of this report provides background information, including Federal Aviation Administration (FAA) guidance regarding symbology, considerations for manufacturers for designing and testing symbology, and an overview of Volpe Center research addressing aeronautical charting symbology. The next three sections contain tables that show navigation aid symbols, airport symbols, and lines and linear patterns. A list of reference documents, including policy and research documents, is included at the end of this report.
