1 (Refer to FAA-CT-8080-2G, Figure 20, area 2.) Why would the small flag at Lake Drummond of the sectional chart be important to a remote pilot?
B. This is a GPS check point that can be used by both manned and remote pilots for orientation.
Technically the answer by itself is correct, but not correct for context of the the question. GPS Checkpoints include all charted airports and heliports, navaids (VOR, Markers, etc) and VFR Checkpoints with a 5-character identifier.
This is not the correct answer.
