    I don't mean to sound like Chicken Little, but....
  Your sectional maps are about to become more cluttered with magenta orbs. 
In the past week I have received three (two in Ohio) notices of proposed
rulemaking for establishment of Class E airspace (formerly referred to as
a control zone).  They are six-nautical miles in diameter and extend from
700 to 1,200 feet agl. If you wonder why there is no airport symbol
associated with them, it is because they aren't for airports.  These are
helicoper point in space, global positioning system, standard instrument
approach procedures (GPS SIAPs) to hospitals.  GPS now makes a legal
(wrong word, I know, but the meaning is more clearly understood)
instrument approach to just about anywhere possible. If you can land
there, you can apply for an approach. Private approaches exist all over
the country.
  These were received in the Great Lakes Region  distribution. Are other
FAA regions sending out the same NPRM's?
 If you have an aerobatic practice area that is not on/nor adjacent to an
airport, you might want to keep your eyes open for future notices. I
haven't fully thought through the ramifications of these new approaches,
but I can see a potential for conflict. Granted, the top surface is 1,200
ft AGL, and that you really may not want to be practicing lower, in some
places you legally can. Any thoughts from the masses?
