If ever the case needed to be made for the whole Q-line to be available as a general policy, how many flying this weekend stumbled across NOTAM B0074/03?
Checking with the AIS office confirmed that this was only applicable above FL200, but with the tools that they have given us, there is no way to get this information other than to telehone them. Fortunately, AvBrief & NotamPlot weeded it out (

guys!), but I'm not sure how!
Just in case you missed it,

here it is:
OTH : FROM 03/01/16 11:25 TO PERM B0074/03
E)FPL AND RPL OF NON 8.33KHZ EQUIPPED FLTS REJECTED UNLESS, IF EXEMPTED, STS/EXM833 IS INCLUDED IN FPL OR RPL
And whilst I'm having a moan, as raised by Flyer mag in the January ish (Page 50, J is for Dubya), AIS don't report French NOTAM LFFA-D4624/03 even when constructing a briefing to destination LFDP, whereas the French system returns it. Interestingly, the French system returns a NOTAM for EGFA (just took a small sample from the EGTT A/D brief) For those that care (Mike, rustle, are you there?) the Q lines are QFALB and QMRLL for the French and English aerodromes respectively)
I'll be doing some more investigation over the next week or so, but it seems the French system (
http://olivia.aviation-civile.gouv.fr/ ) is considerably more useful - as well as giving the complete NOTAM with a variey of search options, it links to the met (if you have a Meteo-France code), and even allows you to file/change a flight plan!
For other insomniacs, although the ICAO decode is only available as a purchasable tome,
http://www2.faa.gov/atpubs/NTM/notapd1.html would be a starting point
