National Airspace System

Refer to Legend 1. The town of Hinton is north of Sioux City airport. Winnebago is south of Sioux City airport. This route is through the Class D airspace, depicted with the dashed blue line. You will need to contact ATC before conducting this flight.

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.

Obstacles are depicted as an upside-down V. The top number, printed in bold, is the height of the obstruction above mean sea level. The second number in parentheses is the height of the obstruction above ground level. The highest obstacle 2 NM northeast of Hertford is 500 feet AGL.

Refer to Legend 1. MOAs are depicted on sectional charts with a shaded, hashed magenta line. You can find information about the MOA on the back of the sectional, including times of operation, altitudes affected, and the controlling agency.

When approaching the holding line from the side with the continuous lines, a pilot should not cross the holding line without ATC clearance at a controlled airport, or without making sure of adequate separation from other aircraft at uncontrolled airports.Answer (A) is incorrect because no part of the aircraft may cross the hold line without ATC clearance. Answer (C) is incorrect because no part of the aircraft may cross the hold line without ATC clearance.

Refer to Appendix 1, Legend 1. Anderson Airport is in the bottom right quadrant of the sectional. The lack of shading around the airport indicates it is in Class G airspace. Small UAS operations in Class G airspace may be conducted without ATC permissions. However, remote pilots should exercise vigilance to ensure they cause no interruption to aircraft traffic.
