As promised AIS are now providing the Q line in their briefs. Working now on the AIS site (if a little slow at the moment, the problem is under investigation).
For those not in the know the Q Line is a line of code to a format laid down by ICAO that is used for selecting and sorting the NOTAM to appear in a brief. Here's an example just taken from the AIS site.
EGHI
COM : Q)EGTT/QCTLT/IV/B/AE/000/999/5057N00121W005
FROM 05/07/01 11:15 TO 05/10/31 23:59 B1321/05
E)SOLENT RADAR OPR WITH LIMITED SSR. ATS OUTSIDE CONTROLLED AIRSPACE
MAY BE LIMITED AT TIMES. ACFT TRAINING WILL BE LIMITED, WITH NO
HOLDING AVAILABLE.
Within the Q Line you will see the height band affected as FL's (000/999), the geographic centre (5057N00121W) and the radius of influence in n.m. (005)
This should enable you to better understand why the item appears in your brief.
