It's scoped as both a/d and en-route. You'd need to ask Ian Fallon how he handles them in this situation.
The key is in the first line of the AIS screenshot. This is the "Q" line, which is part of the ICAO standard NOTAM format laid down in
Annex 15 to the Chicago Convention
The line reads
Q) EGTT/QWALW/IV/M/AW/000/050/5238N00218W010
Here's the decode
EGTT - FIR it falls in
QWALW - NOTAM code derived from ICAO Doc 8400 or 8126. First character (Q) identifies the field, next two identify what it's about, and the last two indicate the condition. WALW measn "Air Display will take place". The code QRTCA used in other NOTAM for the event means "Temporary Restricted Area activated"
IV - Indicates it affects IFR and VFR flight
M - Purpose - Miscellaneous NOTAM: not subject for a briefing but available on request
AW - Aerodrome & NAV Warning
000/050 - Upper and lower limists of the activity
5238N00218W010 - Geographic centre followed by 3 digit radius of influence in nm (in this case 10nm)
So you may well ask why this is "not subject for a briefing"
The answer is that other NOTAM were issued for the event which were mandatory and were marked for inclusion in briefings (B in place of M in the purpose field). The old AIS site allowed you to choose "GENERAL" OR "GENERAL + MISC" to exclude miscellaneous NOTAM if you wanted to. Wisely the new site doesn't give you the option and includes them. Other briefing services may work differently.

Which illustrates the difficulty of producing geographic plots as they all sit on top of each other.
I represent AOPA UK on NOTAM matters, hope this explanation is helpful.
