My point is:
a. If a civilian helicopter needs to be low level to carry out his job and
b. needs to transit a MATZ and
c. is required by law to be above 500' agl
then what is he /she to do if a military controller should deny a clearance when in fact a clearance is not a legal requirement? An interesting conundrum.
I do get your point about blindly bumbling around in an active MATZ, very very stupid I agree. However, just to add another dimension, how do you square the circle of gliders without radios flying in an active MATZ, do they not operate without clearances?
