Learn when drone pilots need sectional charts, which symbols matter, and why a chart alone cannot confirm legal airspace access or flight approval.
Drone pilots in the United States should use current FAA sectional charts for pre-flight airspace and hazard checks, although carrying a paper sectional is not normally required. A sectional shows controlled airspace, airports, obstacles and special-use areas, but it does not itself grant permission to fly there.
In our Aviation & Real-World Flying coverage, “sectional chart” means an FAA VFR sectional for US operations. Other countries publish different aeronautical charts and impose their own drone rules.
Are sectional charts legally required for drone pilots?
No FAA rule generally requires a remote pilot to carry a paper or electronic sectional chart. Under Part 107, however, the remote pilot in command must assess the operating environment, including local airspace, flight restrictions, weather and hazards. Recreational flyers must also know the airspace and obtain prior authorisation where required.
The obligation is to understand the operating area, not to use one particular chart format. A recognised drone airspace application may make the information easier to interpret, but knowing how to verify it against a current sectional remains valuable.
For routine small-UAS operations, flight in Class B, C or D airspace, or within an airport’s Class E surface area, requires prior FAA airspace authorisation. That normally comes through LAANC where available or the FAA’s manual authorisation system. A boundary printed on a sectional identifies the airspace; it neither approves nor rejects the flight.
What should drone pilots look for on a sectional chart?
Drone pilots should concentrate on surface airspace, altitude labels, nearby aerodromes, special-use airspace, terrain and tall obstacles. Our detailed breakdown of sectional airspace colours and symbols covers the full symbology.
| Chart feature | What it means for a drone flight |
|---|---|
| Solid blue or magenta boundaries | Class B or C shelves. Read both the floor and ceiling before deciding which airspace contains the drone. |
| Dashed blue boundary | Class D airspace beginning at the surface; prior authorisation is normally required inside its lateral boundary. |
| Dashed magenta boundary | Class E airspace beginning at the surface for an airport; do not confuse it with the broad shaded magenta area where Class E starts at 700 feet AGL. |
Altitude fractions such as 40/15 | Airspace ceiling over floor in hundreds of feet MSL: 4,000 over 1,500 feet MSL in this example. These figures are not AGL heights. |
| Blue or magenta airport symbols | Blue generally identifies a towered airport and magenta a non-towered airport. Either may have low-flying traffic beyond the depicted airport boundary. |
| Prohibited, restricted, warning, MOA or alert areas | These require further checking. Some prohibit or restrict entry; others indicate activity that creates a serious traffic or operational risk. |
| Obstacle symbols | The main figure gives the obstacle top in feet MSL; the figure in parentheses gives its height AGL. Wires and temporary cranes may not be obvious or charted. |
| Maximum Elevation Figure | A quadrant-wide terrain and obstacle planning figure in hundreds of feet MSL. It is not a drone operating altitude or terrain-clearance guarantee. |
A common error is to treat every magenta-tinted area as controlled airspace at ground level. If Class E starts at 700 feet AGL and the drone remains below 400 feet AGL, the drone is generally in Class G unless a separate surface area covers that position.
How do you use a sectional before a drone flight?
Use the sectional to build an airspace picture for the entire operating area, then combine it with live restrictions and drone-specific authorisation data.
- Obtain the current edition. Check the effective dates rather than relying on a saved image or old paper chart. We provide downloadable current FAA sectional charts for locating the correct chart.
- Plot the whole operating volume. Mark the launch point, intended route, maximum radius and likely recovery area. Checking only one map pin can miss a boundary crossed by the aircraft or a possible flyaway path.
- Determine the airspace at flight altitude. Convert the planned AGL altitude to MSL using local ground elevation, then compare it with the charted floors. If terrain rises along the route, repeat the calculation there.
- Inspect nearby aviation activity. Look for airports, heliports, seaplane bases and published routes. For runway, communications and airport remarks not contained on the sectional, use our explanation of how to check airport details in the FAA Chart Supplement.
- Check hazards and special-use areas. Note obstacles, towers, wires, steep terrain and areas associated with military or other intensive flight activity. A sectional cannot depict every low-level aircraft operation.
- Check live and drone-specific information. Review NOTAMs, temporary flight restrictions, UAS Facility Map values and any applicable security restriction. Obtain LAANC or manual FAA authorisation when required.
- Make a go or no-go decision. Confirm weather, visual line of sight, people and property, site permission and operating-rule compliance. Saving the chart edition and authorisation details creates a useful pre-flight record.
For example, a Class C shelf labelled 40/15 has a floor of 1,500 feet MSL. If the ground is at 600 feet MSL and the drone will reach 300 feet AGL, its altitude is about 900 feet MSL, below that shelf. The pilot must still check for an inner surface area, another airspace boundary and temporary restrictions.
Is a sectional chart enough to decide where a drone can fly?
No; a sectional chart is a base map, not a complete drone clearance tool. The full method for reading terrain, airports and boundaries on VFR sectionals helps with interpretation, but several drone-specific checks sit outside the chart.
- UAS Facility Map grid values are not permission. They indicate altitudes the FAA may be prepared to authorise; the pilot still needs an issued authorisation.
- Temporary restrictions change faster than charts. TFRs, NOTAMs and emergency restrictions require a live pre-flight check.
- Local ground rules are separate. A flight may be acceptable under FAA airspace rules while launching or landing is prohibited by the landowner or site authority.
- Manufacturer geofencing is not the law. An unlocked drone may still be illegal to fly, while an app warning can sometimes be more restrictive than the governing airspace rule.
- The 400-foot limit is not an airspace clearance. Remaining below 400 feet AGL does not override controlled-airspace authorisation, TFRs, prohibited areas or other operating restrictions.
Another outdated assumption is that every drone flight within five miles of an airport requires a telephone call. There is no blanket five-mile notification rule for Part 107 operations. The applicable airspace, authorisation requirements and risk of interfering with airport traffic determine what the pilot must do.
Class G also does not mean “anything goes”. No controlled-airspace authorisation may be needed, but the pilot must still give way to crewed aircraft, avoid disrupting airport operations and comply with all other flight, site and temporary restrictions.
