Last updated: May 14, 2026. Checked against FAA LAANC, UAS Facility Maps, the April 2026 Airman Testing Community Advisory, and the current Remote Pilot ACS.
Why this topic deserves its own Part 107 guide
Airspace is where many Part 107 candidates lose easy points. The generic advice is usually to memorize Class B, C, D, E, and G. That is not enough for the current exam or for real jobs. The FAA now tests whether you can connect a chart symbol, an airport surface area, a UAS Facility Map grid, and an authorization path. In 2026, that matters even more because the FAA announced that, beginning October 27, 2026, the Unmanned Aircraft General - Small test will include some questions with embedded images not included in the printed test supplement. You still need the FAA-CT-8080-2H supplement, but you cannot pass by memorizing only figure numbers.
The working rule is simple: identify the airspace, decide whether it is controlled at the surface for your planned operation, then choose the right authorization workflow. The FAA's LAANC page says drone pilots planning to fly under 400 feet in controlled airspace around airports need FAA authorization before they fly, and LAANC is the near-real-time path when the airport participates. The FAA's UAS Facility Maps page and UASFM FAQ also make a key point candidates often miss: UAS Facility Maps are informational aids. They do not authorize a flight by themselves.
The fast decision tree for Part 107 airspace
Before you think about weather or client timing, answer these five questions in order.
| Question | What it tells you | Exam trap |
|---|---|---|
| Am I in Class G below the Part 107 ceiling? | Usually no FAA airspace authorization is needed | Other Part 107 rules still apply |
| Am I inside Class B, C, D, or surface-area Class E? | Prior FAA authorization is required | Surface Class E is easy to miss on charts |
| Is the airport LAANC-enabled? | Use an approved LAANC service supplier for eligible requests | Calling the tower is not the modern authorization path |
| What does the UASFM grid show? | The altitude likely to process quickly | A grid altitude is not approval |
| Are there TFRs, NOTAMs, special use areas, or local restrictions? | They can block or change the operation | LAANC does not replace full preflight planning |
On the exam, the wrong answer often sounds like old folklore: notify the airport within five miles, monitor the tower, or file a flight plan. Under Part 107, the real issue is authorization from the FAA for controlled airspace. LAANC and FAADroneZone are the workflows. Direct tower notification is not a substitute unless a specific authorization requires it.
What each airspace class means for a drone pilot
Class B, C, and D are the obvious ones because they surround busy towered airports and are shown with strong blue or magenta chart boundaries. If your proposed operation is inside those lateral limits and below 400 feet AGL, you still need authorization before flying. Do not reason that a low drone is invisible to ATC. Part 107 treats the controlled airspace boundary as meaningful.
Class E is more subtle. Most Class E begins at 700 feet or 1,200 feet AGL, so a normal 200-foot drone job may be below it and in Class G. But Class E can also begin at the surface around airports with instrument procedures. On sectionals, surface-area Class E is shown with a dashed magenta boundary. For Part 107 candidates, dashed magenta means stop and ask whether the operation is inside surface Class E. If yes, authorization is required.
Class G is uncontrolled airspace. For most remote-pilot jobs away from airports, Class G below 400 feet AGL is the most straightforward case. You still must comply with Part 107 operating rules: visual line of sight, yielding to other aircraft, 3 statute miles of visibility, cloud clearance, preflight inspection, Remote ID compliance when required, and no careless or reckless operation. The absence of an airspace authorization requirement is not permission to ignore the rest of the regulation.
Special use airspace and other chart notes deserve a separate pass. Military Operations Areas, restricted areas, prohibited areas, national security areas, parachute symbols, glider areas, and temporary flight restrictions create operational risk even when the base class looks friendly. The FAA sample UAG questions repeatedly test whether the pilot knows where to look for current information rather than guessing from the chart alone.
How to read a sectional chart for Part 107, not private pilot trivia
Start with the job location. Put your finger on the site and work outward. First identify the nearest airport symbols. Blue airport symbols generally indicate towered airports; magenta airport symbols generally indicate non-towered airports. That clue is useful, but it is not the final answer. The boundary lines and altitude labels decide the airspace.
Next read the boundary. Solid blue outlines point to Class B shelves. Solid magenta outlines point to Class C. Dashed blue points to Class D. Dashed magenta points to surface Class E. Fuzzy magenta shading usually means Class E begins at 700 feet AGL, which is not the same as surface Class E. A white or tan background without controlled-airspace markings often means Class G below the overlying Class E floor.
Then read altitude brackets as MSL unless the chart says otherwise. A label such as 40/20 means the shelf extends from 2,000 feet MSL up to 4,000 feet MSL. That is essential for manned-aircraft navigation, but for Part 107 the first question is usually whether the controlled airspace reaches the surface where your drone will operate. A Class C outer shelf with a 1,200-foot MSL floor may not affect a 300-foot AGL operation the same way a surface area does.
Finally scan for obstacles and notes. Towers, wind turbines, parachute activity, wildlife areas, stadium TFRs, and national security notes are not decoration. The FAA's official Remote Pilot study guide warns that wires and support structures can be difficult or impossible to see in some conditions. Chart reading is not just an exam skill; it changes the preflight risk discussion with your client.
LAANC, UASFM grids, and DroneZone in plain English
LAANC is the fastest authorization path when available. The FAA describes LAANC as an automated application and approval process through approved UAS Service Suppliers. For a straightforward operation at or below the UASFM grid altitude, approval can arrive near real time. For an operation above the grid altitude but still below 400 feet, including some 0-foot grid requests, a certificated Part 107 pilot can submit a further coordination request through LAANC when the service supplier supports it. The FAA says LAANC requests can be submitted up to 90 days before the flight, and further coordination requests must be submitted at least 72 hours before the requested start time because air traffic personnel review them manually.
UAS Facility Maps are not permission. They show the maximum altitude that may be authorized without additional internal FAA coordination. A grid marked 100 means the FAA may be able to authorize 100 feet AGL quickly at that location. A grid marked 0 does not always mean impossible; it means a near-real-time approval is not available at that altitude and a further coordination request may be needed.
| Situation | Usual path | Planning consequence |
|---|---|---|
| At or below a LAANC grid altitude | LAANC near-real-time request | Can often be handled close to the flight date |
| Above a grid altitude but under 400 feet | LAANC further coordination if available | Submit at least 72 hours ahead and expect manual review |
| Non-LAANC airport or broader/manual authorization | FAADroneZone | Plan much earlier because processing is not near real time |
| TFR, special use, local restriction, or unsafe weather | Separate preflight decision | Authorization does not make the whole operation legal or safe |
FAADroneZone is the manual path for locations or requests not handled through LAANC. The FAA's Part 107 Airspace Authorizations page says manual authorization requests should be submitted at least 60 days before the proposed operation when using that process. That timeline is too long for a last-minute real estate shoot, which is why professional remote pilots check airspace before quoting the job.
The mistake to avoid is treating LAANC as a complete preflight check. LAANC gives an airspace authorization. It does not tell you the weather is safe, your battery is healthy, a TFR has disappeared, your Remote ID module is working, or your visual observer is positioned correctly.
The 2026 testing update candidates should know
The FAA's April 2026 Airman Testing Community Advisory announced that beginning October 27, 2026, the UAG test will include some questions with images that are not in the test supplements. The examples in that advisory include sectional-chart snippets used directly inside UAG questions. This does not make the supplement obsolete. It means your study method must move from figure memorization to chart reasoning.
For tests before October 27, 2026, practice with the FAA-CT-8080-2H supplement and learn how to find figure numbers quickly. For tests on or after October 27, 2026, keep doing that, but also practice from current FAA VFR charts so you can interpret fresh snippets without relying on a memorized diagram. OpenExamPrep practice is built around that skill: identify the boundary, the airport, the floor, the authorization need, and the safest answer.
A 7-day airspace sprint
Day 1: Build the class map. Make a one-page chart of Class B, C, D, surface E, non-surface E, and G. Include the chart symbol, whether authorization is required for common drone altitudes, and the common wrong answer.
Day 2: Work only airport symbols and airport data. Decode towered versus non-towered fields, CTAF, elevation, and runway notes. Do not study weather today.
Day 3: Work only controlled-airspace boundaries. Find examples of dashed magenta, dashed blue, solid magenta, and solid blue. Explain aloud what each one means for a 200-foot AGL mapping job.
Day 4: Study UASFM and LAANC. Pick three airports in a LAANC app or FAA map and compare grid altitudes. Ask whether each sample job can be approved near real time, needs further coordination, or should be moved.
Day 5: Add TFRs, NOTAMs, special use areas, and chart notes. The exam often asks where to check current information, not just what the old chart shows.
Day 6: Mix airspace with weather. A legal authorization is useless if visibility, cloud clearance, wind, or night lighting requirements are not met.
Final takeaways
If a Part 107 airspace question feels hard, slow it down. Name the airspace first. Decide whether it reaches the surface where the drone will fly. Check whether LAANC can authorize the operation. Remember that UASFM grid altitudes are planning information, not approval. Then layer in TFRs, NOTAMs, weather, Remote ID, and the rest of Part 107. That sequence beats memorized mnemonics because it matches the real job of a remote pilot in command.
