Meldex they have a standing instruction that anywhere in the UK there maybe GPS jamming without warning.
I suspect that the first sign that something is kicking off will be the GPS going off line.
I doudt very much they will have time to put a NOTAM out. And it will have zero effect on commercial flights in the area. If they turned off all the DME and VOR's as well it would be chaos.
