    Radio communication is not required in class G airspace, even for IFR operations. Class G is completely uncontrolled. VFR visibility requirements in class G airspace are 1 mile (1.6 km) by day, and 3 miles (5 km) by night, for altitudes below 10,000 feet (3,050 m) MSL but above 1,200 ft AGL. Beginning at 10,000 feet MSL, 5 miles (8 km) of ...

    Separation can also apply to terrain, obstacles, and controlled airspace, wherein an aircraft must stay at a minimum distance from a block of airspace; as an example, all aircraft must be approved by the controller who "owns" the airspace before the aircraft is approved to enter that sector. Separation at cruising altitude (aircraft passing below).

    The first sectional chart was published in 1930; in 1937 the full series of the lower 48 states was completed. These early sectional charts were smaller (most covered two degrees of latitude and six of longitude) with the map on one side; after 1950 the legend and index to adjoining charts was on the reverse.

    Class G airspace extends from the surface to the base of the overlying Class E airspace. Although ATC has no authority or responsibility to control air traffic, pilots should remember there are visual flight rules (VFR) minimums which apply to Class G airspace, [14] and that flight over private property should not be presumed valid.

    TRSAs encompass a primary airport with a class "D" designation, with the TRSA above other controlled airspace (Typically Class E Airspace) with a typical floor of 700 feet or 1,200 feet AGL (Above Ground Level). TRSAs are shown on most VFR (Visual Flight Rules) sectional charts as solid grey with black text.

    A MATZ airspace classification is the same as the airspace classification within which it lies, mostly class G (open airspace) in the UK. In the centre of the MATZ is an aerodrome traffic zone, ATZ. The MATZ airspace has no legal recognised status under the UK Air Navigation Order (ANO) for civil pilots and no prior permission is required to ...
