I must say that I was left pondering the usefulness or otherwise of MATZs as I watched two Hawks in a day (one morning, one afternoon) carrying out aeros in the overhead at a Secret Yorkshire Fast Jet Base last week. There's no way 3000ft of vertical space, or even the 5nm radius, is enough to contain a Hawk shaking its booty in that way. A loop alone must use up 5000ft from base height (says he, not really knowing the answer for a Hawk, but basing this on the Red Arrows' tendency to fly a 'flat' show when the cloudbase is <5000ft AGL).
So in that particular case, I couldn't think of much use for the MATZ apart from IFR traffic, and even for that, most of the procedures I saw wouldn't have been contained in it anyway. Certainly the SID/radar approach I saw drawn on the Tonka sim boards wouldn't have fitted.
