Avbrief/NotamPlot weeded it out because they have the Q Line.
Why can't we see the Q Line? Try this theory.
We asked for it to be provided. CAA/DAP said no.
A court case is pending in Australia between Airservices Australia and Jeppesen. AA, who provide the AIS, is trying to assert copyright in the Australian IAIP, which includes NOTAM, AIC's and the AIP and want to charge Jepp and others for the data. Story

Our own CAA is involved in Eurocontrol's European AIS Database (EAD) project. Within this there is a "Copyright and Service Charging Policy Implementation Task Force".
The Q Line is the key to successful filtering and presentation of NOTAM data. AvBrief get the Q Line because their access to the data is controlled and can eventually be charged for. We do not because we have free access via the Internet and they don't want to make information freely available when plans exist for charging for it in the future.
Now consider the products which use aeronautical data, and which would become more expensive if their publishers had to pay licensing fees to each of the nearly 200 ICAO contracting states. They include:-
Briefing Services
Charts
Flight Guides
Approach Plates
GPS databases
Flight Planning software (e.g. NavBox)
Simulators
FMCS
"Radix malorum est Cupiditas"
Any copyright lawyers out there care to give an opinion on whether you can copyright facts like the length of a runway or the opening hours of an aerodrome?
This month's edition of "General Aviation", the magazine of AOPA UK will carry an article on this subject.
Thanks for the useful link. The full set of decodes is in ICAO document 8126 (Aeronautical Information Services Manual). Anyone interested in the Q Line and its importance could look
