Utility and Recognition of Lines and Linear Patterns on Electronic Displays Depicting Aeronautical Charting Information

摘要

This report describes a study conducted to explore the utility and recognition of lines and linear patterns on electronic displays depicting aeronautical charting information. The study gathered data from a large number of pilots who conduct all types of flight operations. Lines and linear patterns that were useful to different pilot groups were identified based on pilot qualifications, types of flight operations, and typical flight length. Pilots were also asked to identify nine test linear patterns in isolation. This task was difficult, but some linear patterns were more recognizable than others. The tested lines and linear patterns will be considered in the development of an updated SAE International Aerospace Recommended Practices (ARP) document on Electronic Aeronautical Symbols (ARP 5289A). The Federal Aviation Administration or the International Civil Aviation Organization may choose to adopt this industry document by reference at a later date. Note that this research applies to any electronic display that shows the lines and linear patterns tested in this study, regardless of the intended function of the display.
