Figure 8-1. Each student, pilot, and instructor should have a current sectional chart  for the flight area. This handbook departs from the conventional  norm, in that the airspace discussions are  presented in reverse order, in the belief that it  is much easier to learn the airspace from least  complicated to most complicated; also, the  information presented for basic visual fl ight  rules (VFR) weather minimums is only that  necessary for weight-shift control (WSC)  aircraft operations.  The two categories of airspace are regulatory  and nonregulatory. Within these two  categories, there are four types: uncontrolled,  controlled, special use, and other airspace.  Airspace is charted on sectional charts as  shown in the some examples for the specifi c  airspaces on the chapter. The specific  airspace symbols are shown on the legend  for each sectional chart.  [Figure 8-1]  The  WSC aircraft pilot should study and refer  to the specifics of the AIM; FAA-H-8083- 25, Pilot’s Handbook of Aeronautical  Knowledge; and Title 14 of the Code of  Federal Regulations (14 CFR) part 91 for  additional information regarding airspace  and operations within that airspace. Class G or uncontrolled airspace is the  portion of the airspace that has not been  designated as Class A, B, C, D, or E. Class  G airspace extends from the surface to the  base of controlled airspace (Class B, C, D,  and E) above it as shown in  Figures 8-2 and  8-3. Most Class G airspace is overlaid with  Class E airspace, beginning at either 700  or 1,200 feet above ground level (AGL).  In remote areas of the United States, Class  G airspace extends above 700 and 1,200  AGL to as high as 14,500 feet before the  Class E airspace begins.  [Figure 8-2]  The  pilot is advised to consult the appropriate  sectional chart to ensure that he or she is  aware of the airspace limits prior to fl ight  in an unfamiliar area.
