I do check the Notams before flight - I particularly don't want to get mixed up in PJEs. However, I would have missed this because it only appears in the Scottish A8 Fut notam. I would have thought something with a 320nm radius should also have been in the London A8 notam.
I have not been in the habit of looking at the Scottish notams when my flight is within the London FIR and I never thought I was doing anything wrong. What do other pilots do?
Fortunately I don't rely on gps. Thanks for bringing this to our attention on PPRUNE.
