FAA 107 Sectional Chart Reading & Navigation 4

Question 1

When reading a sectional chart, a tower obstacle symbol with its top elevation printed in bold and underlined indicates:

Accepted Answer

The obstacle exceeds 1,000 feet AGL

Answer

Bold, underlined elevation numbers next to an obstacle symbol on a sectional chart indicate the structure exceeds 1,000 feet above ground level.

Question 2

A remote pilot is planning a flight near a TRSA (Terminal Radar Service Area). How is a TRSA depicted on a sectional chart?

Accepted Answer

Solid black lines with the word 'TRSA' and altitude limits noted

Answer

TRSAs are depicted on sectional charts with solid black lines and labeled with 'TRSA' along with altitude limits, distinguishing them from formal airspace classes.

Question 3

On a sectional chart, what color are Class C airspace rings?

Accepted Answer

Solid magenta lines

Answer

Class C airspace is depicted with solid magenta lines forming concentric rings, with ceiling and floor altitudes labeled in hundreds of feet MSL.

Question 4

A sectional chart legend shows a tick-mark symbol with 'UC' labeled. What does this mean for a depicted obstacle?

Accepted Answer

The obstacle is under construction and the height may not be accurate

Answer

The 'UC' label near an obstacle symbol indicates it is under construction, meaning the depicted height may change and pilots should exercise extra caution.

Question 5

What is the purpose of the isogonic lines (lines of equal magnetic variation) printed on a sectional chart?

Accepted Answer

To allow pilots to convert between true and magnetic headings

Answer

Isogonic lines on sectional charts connect points of equal magnetic variation, enabling pilots (and drone operators) to convert true headings from the chart to magnetic headings for navigation.
