FAA 107 Sectional Chart Reading & Navigation 3 — Questions and Answers
Question 1: On a sectional chart, a magenta dashed line surrounding a surface area indicates which airspace class?
- Class E airspace that extends to the surface (Correct answer)
- Class D airspace
- Class C airspace inner ring
- Class B Mode C veil
Correct answer: Class E airspace that extends to the surface
A magenta dashed line on a sectional chart designates Class E airspace that begins at the surface, often around airports without control towers that have instrument approaches.
Question 2: A sectional chart shows a military airport symbol. How is a military airport distinguished from a civil airport?
- Military airports use a tick-mark star burst symbol around the runway layout (Correct answer)
- Military airports are shown only in blue, while civil airports are shown in magenta
- Military airports are depicted with a shield symbol
- Military airports have dashed outlines instead of solid
Correct answer: Military airports use a tick-mark star burst symbol around the runway layout
Military airports on sectional charts are shown with a tick-mark (star-burst) pattern around the airport symbol to distinguish them from civil airports.
Question 3: What altitude is Class B airspace typically depicted as on a sectional chart?
- Solid blue lines with floor and ceiling altitudes labeled in hundreds of feet MSL (Correct answer)
- Magenta dashed lines with a single MSL altitude value
- Blue segmented circles with a single altitude number
- Solid magenta lines with AGL altitudes
Correct answer: Solid blue lines with floor and ceiling altitudes labeled in hundreds of feet MSL
Class B airspace is shown on sectional charts as solid blue lines with both ceiling and floor altitudes expressed in hundreds of feet MSL (e.g., 100/SFC).
Question 4: On a sectional chart, latitude and longitude lines are spaced at what standard interval?
- 30-minute intervals (Correct answer)
- 1-degree intervals
- 15-minute intervals
- 10-minute intervals
Correct answer: 30-minute intervals
Sectional charts display latitude and longitude lines at 30-minute intervals, with tick marks at every minute of arc.
Question 5: A remote pilot notices a bold magenta line on a sectional chart connecting two points. What does this most likely represent?
- A Federal Airway (Victor Airway) above 1,200 AGL (Correct answer)
- A visual checkpoint between two airports
- A VFR waypoint route
- Class E transition area boundary
Correct answer: A Federal Airway (Victor Airway) above 1,200 AGL
Bold magenta lines on sectional charts represent Victor Airways (Federal Airways), which extend from 1,200 feet AGL up to but not including 18,000 feet MSL.
Question 6: What does a blue flag symbol on a sectional chart represent?
- A VFR checkpoint used by pilots for position reporting (Correct answer)
- A restricted area boundary marker
- A mandatory reporting point for IFR aircraft
- A designated drone corridor
Correct answer: A VFR checkpoint used by pilots for position reporting
Blue flag symbols mark VFR checkpoints—prominent landmarks near busy terminal airspace where pilots report their position to ATC.
Question 7: On a sectional chart, an obstacle marked with a high-intensity light symbol (lightning bolt) means the structure:
- Has high-intensity strobe lighting, making it more visible (Correct answer)
- Exceeds 1,000 feet AGL
- Is under construction and height is provisional
- Emits RF radiation hazardous to avionics
Correct answer: Has high-intensity strobe lighting, making it more visible
A lightning bolt symbol on an obstacle indicates it is equipped with high-intensity strobe or flashing lights, aiding in visual detection.
