Given the recent performance improvement, the system at least now seems to be consistently available, but...
Why if I specify Narrow Route width 30nm routing EGBK DCT EGBK am I
not informed of military exercise PHOTON EAGLE which passes within 10nm of the airfield tomorrow morning, consisting of 18 helis operating below 1000ft QFE??!!
Conversely if I specify Narrow Route width 10nm routing EGBK DCT DTY DCT EGBK, which is actually a smaller radius, the exercise is listed (albeit embedded within 2 pages of junk).
The guidance in the FAQ suggests that in order to search a 50nm "local area" around a home airfield, it's necessary to specify
both a search radius of 50nm
and also invent a "DCT x DCT y DCT" route specifying NavAids 50nm North and 50nm South of the field.
That's some whacky programming??!!
