PLOT AND ANNOTATE CONTROLLED AIRSPACE

In addition to applying CHUM information, annotate Class B, C, and D airspace.

Class D airspace extends from the surface to 2500 AGL, but the configuration is individually

tailored, generally having one concentric five statute-mile diameter circle centered about the

primary airport. Chart this in the same manner as depicted on the VFR sectional chart, with a

dashed blue line.

Class C airspace is standard in size with two concentric five and ten mile diameter circles

centered about the Class C airport. The airspace extends vertically from the airport surface up to

4000 feet AGL in the inner circle and from 1200 to 4000 feet AGL above the airport surface in

the outer circle. Airports having Class C airspace are listed in both Aeronautical Information

Manual (AIM) and AP-1 and depicted on low altitude enroute and VFR sectional charts. Figure

2-11 shows the Class C airspace for the Mobile Regional area.

Class B airspace is also listed in the same publications but they are non-standard in size and

shape. Your best sources of information for Class B airspace dimensions are the low altitude

enroute and VFR sectional charts.

To annotate airspace on your chart, outline the defined airspace in pencil, then after double

checking against a VFR sectional chart, apply blue ink, and include the altitude structure of the

airspace, adjusted to MSL.
