SYSTEM AND METHOD FOR IDENTIFYING CHANGES ON NAVIGATION PROCEDURE CHARTS

摘要

A system and method are provided for identifying changes on navigation procedure charts. A processing system is coupled with a user interface and a display device for access and display of old and new navigation procedure charts from different revision cycles. A computer software-based differences engine of the processing system obtains an old navigation procedure chart from an old chart storage memory and a new navigation procedure chart from a new chart storage memory. The differences engine determines changes in information from the old navigation procedure chart to the new navigation procedure chart. The navigation procedure charts may, for example, be aeronautical charts. The changes in information are visually identified such that the user can easily determine the changes that have been made from an old chart to a corresponding new chart.
