Help for NOTAM Maps

There is a red marker for each NOTAM plotted on the map, and a series of smaller ones for each flying site. In addition, the NOTAM markers may have a semi-transparent filled-in circle around them. (Circles with a radius of 10 nautical miles or greater will not be filled in, to ease readability). NOTAMS for danger areas will have the danger area indicated - in red for an activation, green for a deactivation. Some NOTAMs show flight paths; these are shown as black lines, with the red marker on one of the corners of the path

Clicking on a NOTAM marker will show the details of the NOTAM, Clicking on a smaller (site) marker will show the details of the flying site, and point you to the site guide, if it exists.

If there are two or more NOTAMS issued for the same place, the markers for the subsequent ones will be displaced slightly to the east. You will have to zoom in to separate them on the map. To zoom in to any NOTAM, click on the marker. This will bring up the text associated with that NOTAM. Then use the zoom control on the left-hand side of the map to zoom in and out. The map will centre on the marker you have selected.

Each NOTAM marker has a letter on it, depending upon its type:

R for 'Restriction'
D for a 'De-restriction' eg a danger area deactivated.
P for 'Prohibited'.

Since the map is designed for non-powered pilots, NOTAMs issued for for other reasons, eg airfield operations or obstacles, have not been extracted.


The default behaviour for the NOTAM Map is to display the local prohibited airspace,local navigation warnings and the local flying sites on a map of SE England. Thus, you should normally see only the 'Restriction', 'De-restriction' and 'Warning' codes. You can turn off all these features, by clicking on the options below the map. One of those options lets you see only the NOTAMs that apply on the day, and another lets you see the NOTAMs for non-daylight hours.

If you choose to view NOTAMs for the whole country, the program will open up a new page (or tab), and display the entire UK. This larger map will also let you view airspace, and has a national sites index. The data for this has been gathered from a variety of sources, mostly other clubs' site guides. If you know of any errors and omissions in this, please let me know.

The NOTAM information is collected by logging on to the NATS web site, and downloading all the information for the EGTT and EGPX flight Information Regions, ie the whole of the UK. This is done every six hours (1am, 7am, 1pm and 7pm BST), using the 'BHPAuser' user name and password. The briefing number that this generates can be seen at the bottom of the page. The data requested is for seven days ahead.

The usual caveats apply; don't rely on this map for your flight planning, blah blah blah.
