Messages which contain only notice
You do not have a permit.
Messages which require careful attention
Permit for a chart has expired.
You have a permit, but it is valid for
another edition of the cell.
You can check edition of the permit
using the Chart Permits window and
the edition of a chart using the Cell
Status window, both in the Chart
menu.
A typical reason is that the chart has been updated too many times as a new
edition instead of an update. Ask for new permits from your chart agent.
