Working with Terminal Charts

The revision date and the effective date are also printed in the terminal chart header.
If there is no effective date, the chart is effective upon receipt.
When you print a Trip Kit before a terminal chart is effective, both the current and
the future effective charts are included.
On the effective date at 0901 GMT, JeppView expires the old chart by marking it
obsolete with a red dot, and displays the new chart as the current one. The red dot
disappears the next time you update your terminal charts.
For more information about charts with revisions, see Keeping Your Programs Up-to-
Date .
Future Effectivity
Terminal charts sometimes become effective between the standard chart cycle
release dates. At 0901 GMT of the effective date, the new chart icon is marked with
a green dot. The expiring mid-cycle revision chart icon is marked with a red dot. The
old chart and the red dot disappear the next time you update your terminal charts.
