Pilot reference
Class E airspace, explained
Class E is the controlled airspace that is not A, B, C or D. It is most of the sky over the United States, and the part of it that catches pilots out is where it starts.
Where Class E starts
14 CFR 71.71 defines Class E. In practice, its floor is one of four heights:
| Floor | Where | On the sectional |
|---|---|---|
| The surface | A Class E surface area around an airport without an operating tower (or a part-time tower’s off hours), and extensions to B, C, D and E surface areas | Dashed magenta line |
| 700 ft AGL | Transition areas around airports with an instrument approach | Magenta vignette (the fuzzy side marks where 700 ft starts) |
| 1,200 ft AGL | Federal airways, en route areas and the 1,200 ft transition areas that cover most of the country | Blue vignette where the 1,200 ft floor begins; often nothing at all |
| 14,500 ft MSL | Anywhere nothing lower is designated, but never within 1,500 ft of the surface | Not charted as a symbol; it is the default |
Class E extends up to, but not including, 18,000 ft MSL, where Class A begins, and everything above FL600 is Class E again. Below the floor, until something else is designated, the airspace is uncontrolled Class G.
The AIM (Aeronautical Information Manual, chapter 3, section 2, Change 3, effective 9 July 2026) is explicit that the 700 ft and 1,200 ft transition areas “remain in effect continuously, regardless of airport operating hours or surface area status”, and warns not to confuse them with surface areas.
What it requires of a VFR pilot
- No pilot certificate requirement and no ATC clearance or contact requirement for VFR flight.
- Weather minimums (14 CFR 91.155): below 10,000 ft MSL, 3 statute miles visibility and 500 ft below, 1,000 ft above, 2,000 ft horizontal from clouds; at or above 10,000 ft MSL, 5 statute miles and 1,000 / 1,000 / 1 statute mile. Full table on the VFR minimums page.
- In a Class E surface area, VFR needs a 1,000 ft ceiling and 3 statute miles ground visibility to take off, land or enter the pattern (91.155(c) and (d)), unless you get a special VFR clearance.
- Equipment: a transponder with altitude reporting and ADS-B Out at and above 10,000 ft MSL over the 48 contiguous states and DC, excluding the airspace at and below 2,500 ft above the surface (14 CFR 91.215, 14 CFR 91.225).
The misconception worth fixing
The usual mistake is to believe Class E starts at 1,200 ft AGL everywhere, and so to plan a low scud-run under what is actually a 700 ft floor, where the Class E minimums (3 miles, 500 ft below cloud) apply rather than Class G’s (1 mile, clear of clouds). Before a low flight, find the magenta vignette on the chart and know which side of it you are on.
Is Class E controlled airspace?
Yes. Class E is controlled airspace that is not designated Class A, B, C or D. VFR pilots need no clearance to fly in it; IFR flights in it are controlled by ATC.
Where does Class E airspace begin?
At the surface in a Class E surface area, at 700 ft AGL in transition areas shown by a magenta vignette, at 1,200 ft AGL over most of the country, or at 14,500 ft MSL where nothing lower is designated (but not within 1,500 ft of the surface). It extends up to but not including 18,000 ft MSL, and resumes above FL600.
What does the magenta vignette on a sectional mean?
A Class E transition area with a floor of 700 ft above ground level. Inside the shaded edge, controlled airspace starts at 700 ft AGL; outside it, typically at 1,200 ft AGL.
Do I need a transponder in Class E?
At and above 10,000 ft MSL over the 48 contiguous states and DC, excluding the airspace at and below 2,500 ft above the surface, yes: a Mode C transponder and ADS-B Out (91.215 and 91.225), unless ATC authorizes otherwise.
