FREE VISUAL PART 107 STUDY

Visual Sectional Chart Lab

Charts are learned by looking at charts—not by memorizing a paragraph about them. This lab starts with complete teaching references, then pushes you into unfamiliar current FAA chart material.

Training diagrams vs. real charts: these graphics are intentionally simplified teaching references, but the labels and relationships are checked against current FAA chart guidance. They are not navigation products. Current FAA charts, the current FAA Chart User's Guide, NOTAMs/TFRs and required authorization control real operations.

VISUAL 1 · CORE LEGEND

Recognize the main boundary and vignette families

This is the complete core set you should be able to distinguish for controlled/transition airspace questions. Notice that a blue vignette is not identical to a dashed blue line, and a magenta vignette is not identical to dashed magenta.

Common sectional airspace boundary & vignette cues Training reference — use the current FAA legend and exact chart location before making a flight decision. Solid blue — Class B boundaryRead the charted sector ceiling/floor for the exact point. Solid magenta — Class C boundaryClass C sectors also use charted ceiling/floor values. Dashed blue — Class D surface areaClass D normally begins at the surface; charted top is shown in MSL. Dashed magenta — Class E designated to the surfaceDo not confuse this with a magenta Class E transition vignette. Magenta vignette — Class E begins at 700 ft AGLThe faded side indicates the 700-foot transition area. Blue vignette — Class E floor other than 700 ft AGLCommonly 1,200 ft AGL; higher floors may be chart-annotated. Verify the chart. Class G has no dedicated sectional boundary line.Infer it where controlled airspace has not begun. Class A starts at 18,000 ft MSL and is not depicted as a Class A boundary on VFR sectionals.
Test trap: “fuzzy” is common pilot shorthand, but the FAA describes these as vignettes. Magenta vignette = 700-foot Class E transition floor. Blue vignette = a Class E floor other than 700 feet; 1,200 feet AGL is common, but chart annotations can specify another floor.

VISUAL 2 · VERTICAL LOGIC

Think in vertical layers, not just colors

The class at one latitude/longitude can change with altitude. Surface areas, transition floors and Class B/C shelves are different problems.

Airspace is three-dimensional: WHERE + HOW HIGH Surface areaClass D examplecontrolled from surfaceCharted top is expressed in MSL. Transition areaClass E abovestarts at 700 AGLClass G belowBlue vignette commonly marks 1,200 AGL instead. B/C shelf100 / 4010,000 MSL / 4,000 MSLdifferent airspace below shelfRead the exact charted pair at your point.

VISUAL 3 · OBSTRUCTIONS

MSL, AGL and MEF are different numbers

On a charted obstruction, the larger/top figure is the top elevation MSL and the parenthetical figure is the structure height AGL. The Maximum Elevation Figure is a separate quadrant reference.

1549(349)top elevation: 1,549 ft MSLstructure height: 349 ft AGLMEF example175MEF is a quadrant maximum-elevation reference — not a legal drone altitude or substitute for obstacle/site checks.

VISUAL 4 · AIRPORT OPERATIONS

Runway, taxiway, hold-short marking and sign colors

Airport-operation questions can mix signs, pavement markings and traffic information. Learn the color logic instead of memorizing one picture.

Airport surfaces, holding position, and sign colorsRUNWAY — runway markings are whiteTAXIWAY — centerline is yellowRunway holding position: 2 solid + 2 dashed yellow linesApproaching the runway from the solid-line side: hold short unless authorized to cross.18-36white on red = mandatoryAyellow on black = locationB →black on yellow = direction/destination

VISUAL 5 · SPECIAL-USE AIRSPACE

Some blue and magenta boundaries are not Class B/C/D/E

Read the label/designator. Special-use boundaries use their own chart conventions and can be confused with class-airspace colors if you look only at color.

Do not confuse class-airspace lines with special-use airspaceP / R / W areasProhibited · Restricted · WarningFAA charting family: blue boundaryMOA / Alert areasMilitary Operations Area · Alert AreaFAA charting family: magenta boundaryRead the printed name/designator and the chart legend. Color by itself is never the whole answer.

VISUAL 6 · PUT THE CLUES TOGETHER

Work a fictional chart before opening a real one

Use the same sequence every time: exact point → boundary/vignette → vertical limits → airport/frequency → obstruction/special-use feature → current-information check.

Fictional FieldCTAF 122.8 · ELEV 7421549 (349)R-0000fictional restricted areaMagenta vignette edge → Class E transition area begins at 700 ft AGL on shaded sideDashed magenta around airport → Class E designated to the surfaceFictional training schematic — not a navigation product. Use current FAA charts for real flight planning.
  1. What encloses Fictional Field? A dashed magenta line, meaning a Class E surface area in this training example.
  2. Which side of the magenta vignette has the 700-foot Class E transition floor? The shaded side.
  3. What is the CTAF? 122.8 MHz.
  4. How high is the obstacle above local ground? 349 feet AGL; its top is 1,549 feet MSL.
  5. What should R-0000 make you do? Identify the restricted area, determine its current status/applicability, and do not assume color alone answers the question.

THE METHOD

Use the same scan every time

1. Exact point

Locate the precise point being asked about. Airspace changes across boundaries.

2. Boundary + vertical limits

Identify the line/vignette family, then ask what begins at the surface and what begins above you.

3. Airport data

Read tower/CTAF/weather frequency, field elevation and runway information from the chart or supplement.

4. Hazards + current info

Scan obstructions and special-use airspace, then verify current chart edition, NOTAMs/TFRs and authorization requirements.

UNFAMILIAR-CHART DRILL

Now remove the training wheels

FAA testing guidance says UAG questions begin using embedded images not found in the printed supplement on October 26, 2026, including up-to-date chart imagery. Practice with chart areas you have not memorized. Open a current FAA VFR chart and answer: What airspace is at the surface? What begins above it? Which airport/frequency matters? What nearby obstruction or special-use feature changes the plan?
