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?
C. This indicates that there will be a large obstruction depicted on the next printing of the chart.
If the FAA cartographers know of a pending obstruction, it would be on the chart. VFR charts are updated every 6 months, so to err on the side of safety, obstructions are charted if they will be constructed before the next chart revision.
Any new obstructions will be included in NOTAMS, in Chart Supplements (formerly the Airport/Facility Directory), and in the VFR Chart Update bulletins.
This is not the correct answer.
