Interpretation should include the following:

- The charts provide an abundance of information, including airport data, navigational aids, airspace, and topography.
- By referring to the chart legend, a pilot can interpret most of the information on the chart.
- A pilot should check the chart for other legend information, which includes ATC frequencies and information on airspace.
- These charts are revised semiannually, except for some areas outside the conterminous United States, where they are revised annually.
