Oh dear. Just taken a look at our colleagues over
there and they're suggesting that these NOTAMs have been issued in reaction to the Grob/glider collision last weekend. Seems like a rather pointless exercise. If they have really decided that the risks are now too great, they might be better to restrict all AEF cadet flying to within MATZs or controlled airspace rather than pretend that issuing a NOTAM will increase the lookout performance of civil pilots in the area (assuming of course that this was the cause of last weekend's midair). That would cover 8 of the 12 UAS/AEF airfields.
