National Airspace System

Refer to Legend 1. Restricted areas are identified on sectional charts with an "R" followed by a number. You can find information about restricted areas on the back of the sectional chart.

When a manned aircraft is approaching to land at an airport in Class G airspace without an operating control tower, each pilot of an airplane will make all turns to the left unless the airport displays approved light signals or visual markings indicating that turns should be made to the right (which will be detailed in the Chart Supplement U.S. Answer (A) is incorrect because the traffic pattern altitude will vary for each airport and aircraft; however, all turns should be to the left unless otherwise indicated. Answer (C) is incorrect because the traffic pattern altitude will vary for each airport and aircraft; however, all turns should be to the left unless otherwise indicated.

Hilton Head Airport is located in Class C airspace, from the surface up to 4,100 feet MSL (41/SFC) as shown by the solid magenta line encompassing the airport. The surface area Class C airspace extends 5 miles out from the center of the airport.

Hayward Executive is located in Class D airspace up to but not including 1,500 feet MSL as depicted by the blue segmented line surrounding it. Note that Class C begins at 1,500 feet MSL in that sector and goes up to the bottom of the overlying Class B (noted by the "T" in the altitude description).

Georgetown Airport is outside the magenta shaded area, which indicates the floor of Class E airspace is at 1,200 feet AGL. The airport elevation is given in the airport data as 2,623 feet MSL. Therefore, the Class E airspace above Georgetown Airport is 3,823 feet MSL (2,623 + 1,200). Answer (A) is incorrect because Class E airspace begins at the surface only when surrounded by a magenta segmented circle. Answer (B) is incorrect because Class E airspace begins at 700 feet AGL inside the magenta shaded areas.

According to the chart, the ATC control tower frequency is 120.50.
