I accept that a disappointingly large number of PPL's fail to brief themselves adequately. There's no excuse. Being an ATCO at a very busy, predominantley GA airfield, I'm often on the wrong end of converstions with people who shouldn't be let out with a shopping trolley, let alone half a ton of flying metal.
My point, however, is that military sorties are often flown extremely close my ATZ and regularly through the Instrument Approach procedures. IMHO, this is equally silly. The ATZ dimensions offer no effective protection to my traffic. Flying a 3° glidepath on the instrument approach will put you below 1000' over a mile from the ATZ boundary and the circuit often extends beyond 2 miles when we're integrating Learjets with Cessna 150's. Wouldn't it be mutually beneficial if the military gave busy civil fields in the FIR a wider berth? Maybe MATZ dimensions?
