    • Abstract:
      There is currently no common symbology standard for the

      electronic display of navigation information. The wide

      range of display technologies and the different functions

      these displays support make it difficult to design symbols

      that are easily recognized across platforms. This paper

      presents the findings of an experiment that addressed the

      issue of symbol stereotypes, i.e., whether symbols have key

      features that are necessary for recognition. Pilots were

      shown symbols for navigation aids collected from five

      aviation display manufacturers and published documents.

      They were asked to indicate whether they considered the

      symbol shapes to be representative of a specific symbol

      type. The results showed that pilots do have stereotypes

      regarding what symbol shapes are representative of a

      symbol type. Stereotypical shapes for navigation symbols

      were identified despite variations in the size, color, and fill

      with which the test symbol shapes were presented. The

      results suggest that symbol stereotypes exist and should be

      considered in the design of electronic symbols to maintain

      safety. While the scope of this work addresses electronic

      navigation symbology, the techniques used here are

      applicable to addressing other types of symbology.
