MATzs
Going back a few posts, and just in case anyone is unaware, a MATZ provides protection only for military / military traffic.
Legally, civvie traffic only has to observe the ATZ, which is the much smaller 2000' / 2 or 2.5 mile cylinder.
It may not be sensible to drive your puddle jumper across a MATZ at 4 miles out, but its not of itself illegal.
