If you don't call you won't have to worry about what to say.
Let's face it, a MATZ is not worth the paper it is depicted on, they don't completely protect the procedural IAPs, especially the cumbersome 'pan-handles'. A 'Government aerodrome' ATZ cannot contain a fast-jet circuit. If military operations are that desperate for protection why not give them a simple 5nm radius Class G Rule 45 ATZ and be done with it. The current MATZ dimensions and recognition are a joke as far as civil users are concerned.
I'm staggered that such a military-only requirement ever found its way into a civil AIP. The over-'control' by military ATSUs, especially outside their so-called MATZs/CMATZs/pseudo Class D, is becoming an infringement upon civil liberties. The sooner they learn to correctly provide the different air traffic services to civil aircraft the better. The 'my plane is bigger/faster than yours, get out of the way' mentality is outrageous. On FIS just pass VFR flights the flippin' traffic information. It's not difficult. What on earth are they teaching at Shawbury these days?
