Part 107 Sectional Chart Practice: 12 Free Questions
Twelve chart-reading questions with answers: airspace classes and altitudes, CTAF frequencies, obstruction heights, maximum elevation figures and airport symbols. No sign-up, and every explanation cites the chart legend or the Part 107 rule behind it.
- Eight questions describe the chart symbol in words, so you can answer them right here
- Four point to a figure in the FAA's free testing supplement, FAA-CT-8080-2H (PDF): Figure 20 and Figure 26. Open it in another tab.
- Legend 1 in the same PDF is the sectional chart legend. It is the source for most answers below.
Why chart reading matters more now: starting October 26, 2026, the FAA test can show sectional chart images that are not in the supplement. Here is what changed on October 26 and what didn't.
Read any chart question in four steps
- Find the spot. The airport, the tower, the numbered area. Read only what touches that spot.
- Name the airspace from the line color and style, using the table below.
- Read the numbers. Shelf labels, boxed ceilings, obstacle heights, the airport data block.
- Apply the rule. Authorization under 14 CFR 107.41, altitude under 107.51.
The symbols these questions use
| On the chart | What it means |
|---|---|
| Solid blue line | Class B. Ceiling over floor in hundreds of feet MSL. |
| Solid magenta line | Class C. Ceiling over floor in hundreds of feet MSL; SFC means the surface. |
| Dashed blue line | Class D. Ceiling in a dashed box, in hundreds of feet; a minus sign means up to but not including. |
| Dashed magenta line | Class E starting at the surface (a Class E surface area). |
| Faded magenta band | Class E starting 700 feet above the ground. Below it is Class G. |
| Faded blue band | Class E starting 1,200 feet or more above the ground, next to Class G. |
| Blue airport / magenta airport | Blue has a control tower; magenta does not. |
| Star after CT frequency | The tower operates part-time. |
| C in a solid circle | Follows the CTAF frequency. |
| 285 L 72 122.95 | Field elevation 285 feet, runway lights on sunset to sunrise, longest runway about 7,200 feet, UNICOM 122.95. An asterisk before the L means lighting limitations. |
| 2049 over (1149) by an obstacle | Top at 2,049 feet MSL; 1,149 feet above the ground. |
| Large and small number in a quadrangle | Maximum Elevation Figure: thousands and hundreds of feet MSL. |
| R in a circle | Restricted or private airport. |

Practice on a real, current chart
The supplement figures are from 2018, and the new on-screen questions use recent charts. Download a current sectional for your area from the FAA's VFR chart page (free), pick three airports you have never heard of, and for each one write down the airspace at the surface, whether you'd need authorization, the CTAF, and the tallest obstacle within a few miles. Then check yourself against the legend.
For the rest of the test, take our free Part 107 practice test.
