What airspace is most of the US?

Most airspace in the United States is class E. The airspace above FL600 is also class E. No ATC clearance or radio communication is required for VFR flight in class E airspace. VFR visibility and cloud clearance requirements are the same as for class C and D airspaces when below 10,000 feet (3,000 m) MSL.

The U.S. aviation system is the safest in the world, but one close call is one too many. The FAA and the aviation community are pursuing a goal of zero serious close calls, a commitment from the Safety Summit in March. The same approach virtually eliminated the risk of fatalities aboard U.S. commercial airlines.

Military Operations Area (MOA) is designated outside of Class A airspace, up to 17,999 Mean Sea Level (MSL). A MOA separates or segregates certain non-hazardous military activities from Instrument Flight Rule (IFR) traffic, and identifies where these activities are conducted for Visual Flight Rule (VFR) traffic.
