If after updating permits and charts in ECDIS you receive message in ECDIS chart list "NOT UPDATED" for one or more charts, there are some easy checks you can do:
1. Check in Navtracker that the chart(s) are still in current portfolio (product list or op.area if PAYS)
2. Check if cell is cancelled or replaced in Primar database:
http://primar.ecc.no/primar/portal/public/cancelledCellView.jsf
3. Check if cell is cancelled or replaced in UKHO database:
https://www.admiralty.co.uk/AdmiraltyDownloadMedia/AVCS/REPLACEMENTS%20FOR%20CANCELLED%20CELLS.xls
If cancelled or replaced -> delete the charts from the ECDIS
If not cancelled or replaced, and still in your portfolio > send email to [email protected] with cell name(s)
