National Airspace System

When aircraft are approaching each other head-on, or nearly so, each pilot of each aircraft (regardless of category or size) shall alter course to the right.

Contact with ATC must be made when operating within Class D airport, which is indicated by the blue airport and the blue dashed line surrounding it. The radius of Class D in the case is 4 NM, which is the common standard radius, although configuration of Class D is individually tailored for some airports.

Refer to Appendix 1, Legend 1. Airports having control towers are shown in blue, all others in magenta.Answer (A) is incorrect because Class A airspace is not depicted on a Sectional Chart; Class C airspace is magenta; and Class E airspace is both blue and magenta depending on where the floor of the airspace starts. Answer (B) is incorrect because airports with control towers are shown in blue.

The thick blue lines on the sectional chart indicate the boundaries of the overlying Class B airspace. Within each segment, the floor and ceiling are denoted by one number over a second number or the letters SFC. The floor of the Class B airspace is 4,000 feet MSL.

Refer to Appendix 1, Legend 1. The flag symbol represents a visual checkpoint used by manned aircraft to identify the position to initiate their contact with Norfolk Approach Control. As a defined checkpoint, a higher volume of air traffic should be expected there.

The hill has a height of 4,960 MSL; therefore an sUAS may be flown up to 400 feet AGL, which is 5,360 feet. The floor of airspace such as Class E is in AGL not MSL.
