Class E airspace for drone pilots
Class E is controlled airspace with several forms on a sectional. Only a Class E surface area, drawn with a dashed magenta line around an airport, needs prior ATC authorization under 14 CFR 107.41. Class E that starts at 700 or 1,200 ft AGL sits above a 400 ft drone and needs none.
What is Class E airspace?
The study guide defines Class E as the controlled airspace that is not Class A, B, C or D, and says a large amount of the airspace over the United States is Class E. The AIM lists its purposes: surface areas for airports without an operating tower, extensions to a surface area, transition areas, en route domestic areas, Federal airways and offshore airspace. Those purposes produce different chart looks and very different consequences for a drone.
The AIM also says no separation services are provided to VFR aircraft in Class E, and no specific entry requirements apply to manned pilots. The study guide's practical summary is that in most cases a remote pilot does not need ATC authorization in Class E. The exception is the surface area around an airport, which the AIM says is configured to contain all instrument procedures.

How do I tell which Class E type I am looking at?
| Type | Chart look | Where it starts | Part 107 authorization |
|---|---|---|---|
| Surface area | Dashed magenta line | The surface | Yes, inside the lateral boundary |
| Surface area extension | Narrow dashed magenta lobe off the circle | The surface | Treat as part of the surface area (AIM) |
| Transition area, 700 ft | Faded magenta band (vignette) | 700 ft AGL | No, at or below 400 ft AGL |
| Transition area, 1,200 ft | Faded blue band (vignette) | 1,200 ft AGL | No |
| Floor in MSL | A symbol with a number, with the word ceiling or floor | The charted MSL altitude | Only if you reach it |
| Federal airways | Blue airway lines | 1,200 ft AGL to below 18,000 ft MSL | No |
| Nothing special charted | No band | 1,200 ft AGL unless the chart designates otherwise (Chart Users' Guide) | No |
The Chart Users' Guide says Class E surface airspace is symbolized by a magenta dashed line, that Class E exists at 1,200 ft AGL unless designated otherwise, and that a magenta vignette marks a floor of 700 ft above the ground. A blue vignette marks where Class E starts at 1,200 ft AGL or higher and abuts uncontrolled airspace that extends higher, and differing floors above 700 ft are annotated with a symbol and number. The AIM states the extension rule directly: Class E arrival extensions become part of the surface area and are in effect during the same times.

Do I need authorization in Class E?
Only in one case. 14 CFR 107.41 requires prior authorization "within the lateral boundaries of the surface area of Class E airspace designated for an airport". The study guide puts it plainly: in most cases a remote pilot will not need ATC authorization to operate in Class E. Everything else in Class E, from the shaded bands to airways, starts at 700 ft AGL or higher, above your 400 ft ceiling.
When you do need it, the process is the same as for Class B, C and D.
Part 107 gives you two routes to the authorization. LAANC works through an FAA-approved service supplier's app and usually answers in near real time when you ask for an altitude at or below the UAS Facility Map value for that spot. If you need more than the map allows, you can send a further coordination request for up to 400 ft AGL; the FAA asks for these at least 72 hours before the flight, and you can file up to 90 days ahead. Airports that are not LAANC-enabled go through FAADroneZone instead, where the FAA says processing historically takes up to eight weeks. Unless the authorization says otherwise, you do not call the tower before you fly.

How do I read a Class E surface area on a chart?
Look for the dashed magenta line around an airport symbol that shows no tower frequency (non-towered airports use magenta type). The AIM says an airport qualifies for a Class E surface area only if it has weather observation and reporting capability and communications capability exists with aircraft down to the runway surface, so there is often an AWOS or ASOS frequency in the data block.
Worked example
Jamestown, North Dakota
On the free Devils Lake chart (Figure 26), Jamestown Regional is marked with an ASOS frequency, a field elevation of 1,500 ft MSL and a CTAF of 123.0, and a dashed magenta line around it. That line marks a Class E surface area. A drone at 200 ft AGL anywhere inside that dashed outline needs prior authorization. A drone 200 ft AGL just outside the line, over uncontrolled ground, does not.
The same figure has the opposite case at Cooperstown, North Dakota: a faded magenta ring around the airport means Class E begins 700 ft AGL there. A flight at 350 ft AGL inside that ring is in Class G and needs no authorization. Tap both in the Devils Lake lesson.
How do I convert a Class E floor between MSL and AGL?
Most Class E floors you meet are already AGL (700 or 1,200), so there is nothing to convert. When a chart prints an MSL floor, subtract the ground elevation to get feet AGL.
Worked example
Reading a charted floor
Say a symbol on the chart shows a Class E floor of 3,500 ft MSL and the ground under your site is 2,900 ft MSL. The floor is 600 ft AGL. Your 400 ft AGL flight is 200 ft below it, in Class G. If the ground were 3,300 ft MSL, the floor would be only 200 ft AGL and the same 400 ft flight would be inside Class E, which still needs no authorization because it is not a surface area.
Where no floor is charted at all, the study guide says Class E begins at 14,500 ft MSL, and the AIM says Class E below 14,500 ft MSL is charted on sectionals. Neither matters for a drone limited to 400 ft AGL except in high mountain terrain.

What is a sensible order of checks for a Class E flight?
- Look for a dashed magenta line around an airport near your site. If you are inside it, or inside one of its narrow lobes, you are in a surface area or extension and need authorization.
- If you see only faded magenta or blue shading, the Class E floor is 700 ft AGL or higher, above your 400 ft limit. No authorization applies, but the 107.51 limits and 107.37 yield rule still do.
- If a nearby tower is part time, check the Chart Supplement. A Class D that falls back to Class E at night keeps a surface area, so authorization may still be needed.
- If the chart shows a charted floor symbol close to your altitude, convert MSL to AGL with a ground elevation before relying on it.
The common mistake is stopping at the first step: seeing magenta and assuming authorization, or seeing shading and assuming the whole airport area is clear. Dashed means surface area. Faded band means high floor.
How does Class E relate to the other classes?
Class E is the glue. It sits above Class G, around and above Class D, C and B, and takes over from them when a part-time tower closes. The Chart Supplement entry might say "other times CLASS E", and the 700 and 1,200 ft AGL transition areas stay in effect regardless of airport hours. The AIM warns not to confuse them with surface areas or extensions.
- Class G is the uncontrolled space beneath the Class E floor.
- Class D hands over to Class E at night or on weekends when the tower closes.
- The Chart Supplement tells you the hours and what airspace applies at other times.

What are the common test traps for Class E?
- Applying 107.41 to every Class E. It applies to surface areas, not to the 700 and 1,200 ft AGL transition areas.
- Mixing up the shading colors. Magenta vignette is 700 ft AGL. Blue vignette is higher (typically 1,200 ft AGL) with Class G below.
- Forgetting extensions. A dashed magenta lobe off a circle is a surface area extension, which the AIM says becomes part of the surface area.
- Dashed magenta versus dashed blue. Dashed magenta is Class E surface; dashed blue is Class D. Both need authorization.
- Reading the 14,500 ft number. It is MSL and irrelevant to a 400 ft AGL drone except on very high terrain.
