Why this domain matters
Airspace and charts make up 20% of the current scored blueprint. That is about 12 items in a 60-question set. Learn to read sectional excerpts, find points by latitude and longitude, and identify airspace. You will also use airport symbols, frequencies, terrain, and obstacle heights.
How it works
Check the airspace at the planned location and height. Part 107 needs prior ATC authorization for Class B, C, or D, and within a Class E surface area designated for an airport (E2). Class E extensions and elevated Class E are different cases. Class G does not require that airspace authorization, but the other flight rules still apply.
Learn the chart marks. Solid blue lines are Class B; solid magenta lines are Class C. Dashed blue is Class D. Dashed magenta marks Class E at the surface. A magenta vignette (faded shading) marks Class E starting at 700 ft AGL. Then read the map. Latitude lines lie east-west but measure north/south. Longitude lines run north-south but measure east/west. Airport data blocks give runway, elevation, and frequency clues. Finally, check the temporary layer: NOTAMs and TFRs can change the answer between chart cycles.
Chart reading checkpoint
Learn one chart layer at a time, then recombine them.
Use the dedicated labs to isolate coordinates, airspace volume, symbols, and airport radio. The full sectional flight deck puts those layers back together on official testing figures.
Recommended first
Learn the whole sectional as one connected scene
Drag an aircraft across numbered coordinates, watch the same Class B/C/D volume from the side, decode the flag, towers, MEF, and frequencies, then apply it all to the real FAA testing figures.
NOTAMs and TFRs
Charts show the baseline. NOTAMs show what changed.
A sectional can be current and still miss the thing that matters today. NOTAMs carry time-critical changes such as TFRs, runway closures, communication outages, temporary obstacles, firefighting activity, military activity, and security restrictions.
Exam shortcut: temporary, current, effective time, wildfire, stadium, VIP, disaster, or flight restriction usually points to NOTAM/TFR. Controlled-airspace permission still means LAANC or FAA authorization.
- TFR
- Temporary flight restriction. Often the exam's cleanest NOTAM clue.
- FDC
- Flight Data Center notice. TFRs are issued as FDC NOTAMs.
- AIRSPACE
- A temporary area, altitude block, activity, or restriction.
- OBST
- Obstacle issue such as a crane, tower, or obstruction-lighting problem.
- RWY / TWY
- Runway or taxiway status that can change manned traffic flow.
- COM / SVC
- Communication or service outage such as ATIS, lighting, tower, or fuel.
Official chart reference
When a symbol looks unfamiliar, check the FAA guide first.
The Aeronautical Chart Users' Guide is the FAA's chart symbol dictionary. Use it for line styles, airport data, obstacles, special-use areas, and chart notes. It explains the chart; it does not authorize a drone flight.
Altitude reference checkpoint
MSL is for chart elevations. AGL is for local height.
If the question is about a sectional shelf label, airport elevation, terrain, MEF, or the first number in an obstacle label, think MSL. If it is about the Part 107 400 ft limit, Class E starting at 700 or 1,200 ft, METAR cloud bases, or the parenthetical obstacle number, think AGL.

| Concept | What to know |
|---|---|
| Class B | Surrounds the busiest airports. Solid blue chart lines. Prior ATC authorization is needed when the planned flight enters Class B. A flight below an elevated shelf is outside that shelf; check the airspace beneath it. |
| Class C | Busy airports with a tower and radar. Solid magenta chart lines. Prior ATC authorization is needed when the flight enters Class C. Being inside a shelf footprint does not mean being inside the shelf vertically. |
| Class D | Towered airports with dashed blue chart boundaries. Prior ATC authorization is needed while Class D is active. For a part-time tower, check published hours and the airspace that applies when it closes. |
| Class E | Dashed magenta marks Class E at the surface. Faded magenta marks a 700-ft AGL floor. The Class E area that needs Part 107 authorization is the surface area designated for an airport (E2). Do not apply that rule to every surface extension. |
| Class G | Uncontrolled airspace. No ATC authorization needed for drones, but all other Part 107 rules still apply. |
| LAANC | LAANC stands for Low Altitude Authorization and Notification Capability. Use it to request FAA airspace approval. Map grid heights help plan the request; they do not grant permission. Read the approval and its limits before flight. |
| Airport markers | Blue airport symbols depict towered airports; magenta symbols depict non-towered airports. Blue does not prove the tower is operating now. Check published hours and NOTAMs. The runway shape helps show the runway layout. |
| Airport data blocks | Airport labels can show name, elevation, longest runway, lighting, CTAF/tower frequency, ATIS, and special notes. They aid situational awareness; they do not grant drone authorization. |
| VFR checkpoint flag | A magenta flag marks a VFR checkpoint: a named visual reporting point. A stand-alone VFR waypoint uses a four-point star. They may be collocated, but the flag itself means checkpoint. |
| FAA Chart Users' Guide | The official FAA symbol dictionary for aeronautical charts. Use it to confirm line styles, airport data, obstacles, special-use airspace, and chart terms; it does not replace current NOTAM/TFR or LAANC checks. |
| MSL vs AGL | MSL is altitude above mean sea level and is used for most chart elevations, airport elevations, MEF, obstacle top elevations, and airspace shelf labels unless marked otherwise. AGL is height above local ground and is used for Part 107's 400 ft limit, Class E 700/1,200 ft floors, METAR ceilings, and obstacle heights in parentheses. |
| Shelf floor/ceiling labels | Class B and C shelf numbers are written ceiling over floor in hundreds of feet MSL. 40/15 means 4,000 ft MSL over 1,500 ft MSL; 40/SFC means 4,000 ft MSL down to the surface. Class D uses a bracketed ceiling such as [25] for 2,500 ft MSL. |
| Runway numbers | Runway numbers approximate magnetic heading divided by 10: runway 18 is roughly 180 degrees, runway 36 is roughly 360 degrees. |
| Traffic-pattern position | Final for runway 18 means the aircraft is north of the runway, heading south. Final for runway 36 means south of the runway, heading north. On left downwind, the runway is on the pilot's left. |
| Latitude/longitude & scale | Read latitude first, longitude second. Latitude parallels run east-west but measure north/south. Longitude meridians run north-south but measure east/west. On U.S. sectionals, latitude is normally north and longitude is normally west. |
| Minutes and distance | One minute of latitude is about 1 nautical mile. If only latitude changes, the answer is north/south; if only longitude changes, the answer is east/west. Use the latitude side scale for distance, not the top longitude scale. |
| Special-use airspace | Prohibited, restricted, warning, MOA, alert, and controlled firing areas each signal a different hazard or permission issue. |
| Other airspace areas | Know TFRs, MTRs, parachute jump areas, TRSAs, National Security Areas, VFR routes, and airport advisory areas. |
| NOTAMs | NOTAMs publish abnormal, time-critical NAS status: temporary restrictions, airport/service changes, runway closures, communication outages, obstructions, and hazards. |
| FDC NOTAMs and TFRs | Temporary Flight Restrictions are issued by FDC NOTAM. Read the effective time, radius or boundary, altitude block, reason, and coordination contact. |
| NOTAM search habit | Use FAA NOTAM Search and the Graphic TFR map before flight, especially near airports, stadiums, wildfire/disaster response, VIP movement, and public events. |
| Wire environment | Check towers, guy wires, powerlines, and unlit obstacles at the site. Wires can be hard to see from the air. FAA guidance advises staying at least 2,000 ft to the side of skeletal towers. This is hazard guidance, not a separate Part 107 minimum. |
| Thermal plumes | Smoke stacks, cooling towers, and fires can create rising air and turbulence that can exceed a small drone's control margin. |
| Aircraft and structure lighting | At night, learn the difference between manned-aircraft lights, obstruction lighting, and the drone's required anti-collision light. |
