Methods of promulgation of chart-correcting information

For navigational chart-correcting information and the Admiralty Raster Chart Service, the following methods of promulgation which depend upon the urgency, scope and complexity of the data, are used:

1. Radio Navigational Warning. There are three types of navigational warnings: NAVAREA warnings, coastal warnings, local warnings.

2. Permanent Chart-Correcting Notice to Mariners (NM). NM is used for the prompt dissemination of textual permanent navigational safety-critical information, which is not of a complex nature.

3. Notice to Mariners Block. NM Block is used where there is a significant amount of new complex safety-critical data in a relatively small area or where the volume of changes would clutter the chart unacceptably if amended by hand.

4. Urgent New Edition (UNE). UNE is a new edition of a chart not scheduled into the UKHO charting plan, but urgently produced when there is a significant amount of new data to be disseminated which is urgent but due to volume or complexity of the data is not suitable for NM or NM Block. Urgent New Editions, due to their urgency, may be limited in the amount of information, which is included, i.e. they may not include all non safety-critical information.

5. Preliminary Notice to Mariners. PNM is used where early promulgation to the mariner is needed, and:

   1. Action / work will shortly be taking place (e.g. harbour developments) or

   2. Information has been received, but it is too complex or extensive to be promulgated by permanent chart-correcting NM or

   3. Further confirmation of details is needed. A permanent chart-correcting NM will be promulgated or NE issued when the details have been confirmed or

   4. For ongoing or changeable situations such as bridge construction across major waterways. A permanent chart-correcting NM will be promulgated or NE issued when the work is complete.

6. Temporary Notice to Mariners (TNM). TNM is used where the information will remain valid only for a limited period of time.

7. New Edition (NE) and New Chart (NC). A NE is produced where there is a large amount of new data or a significant amount of accumulated data, which is non safety-critical. A NC is issued if it embraces an area not previously charted to the scale shown or it embraces an area different from an existing chart, or it introduces different depth units.

8. Non Safety-Critical Information. Information which is assessed as being non safety-critical or appropriate for promulgation by RNW, NM (permanent, block, preliminary or temporary), or UNE because of its minor nature, is recorded to await the next routine correction of the chart by NE or NC.
