In the development of aeronautical charts and navigation displays, criteria are needed for two fundamental design decisions What information should the chart contain. How should that information be displayed. The purpose of the present research was to test two hypotheses concerning cartographic design. One experiment dealt with a specific aspect of information content in aeronautical charts, and the other dealt with an aspect of information display in aeronautical charts. The experiments served two additional purposes. One was to provide a preliminary assessment of chart types by comparing orientation performances with the two charts most commonly used by pilots of light attack aircraft the Sectional Aeronautical Chart and the USAF Operational Navigation Chart ONC. The other purpose concerned a methodological question, which is described in detail in this report, dealing with whether or not the sensitivity of the performance measures obtained by the cinema method could be increased by certain changes in the experimental procedures.
