MATZs. Unregulated as far as civil aircraft are concerned. Not worth the half-mils they are printed on. If Military aerodromes really do want to operate in a known traffic environment then they should secure some 5nm radius Rule 45 airspace around them. Until then they will have to put up with the consequences of an unknown traffic environment outside their ATZs. I am staggered that nats have the temerity to publish MATZs in a civil AIP. Utter nonsense. Should be either be regulated or not.
