How do I know where my Class E starts?

Class E airspace rarely goes all the way to the surface, and in non-mountainous terrain, the floor of Class E airspace is typically 700 feet or 1,200 feet AGL. But how can you know the difference? The answer lies within the faded magenta circle that typically surrounds nontowered airports.

Class E surface areas extend upward from the surface to a designated altitude, or to the adjacent or overlying controlled airspace. When designated, the airspace will be configured to contain all instrument procedures.

Class E-5 airspace areas may be established with MSL floors above 1,200 feet AGL. Normally floors will be at least 300 feet below the minimum IFR altitude.

Class E airspace does not prohibit drone flight to anyone, but some circumstances require prior authorization. Class E4 and E3 airspaces do not require prior authorization, but Class E surface area (E2) airspace surrounds small airports and does require airspace authorization.

MORE DETAILS

Class E airspace has no requirements for communication when flying VFR. You only have to maintain two-way communication in Class E airspace when flying IFR.

Class E airspace: Transponder requirements vary depending on the altitude of the aircraft: Below 10,000 feet MSL (mean sea level): A transponder is not required unless the aircraft is within 30 nautical miles of a Class B airport.

Class E Transition Areas It often surrounds individual airports or groups of airports. So why does the Class E airspace suddenly drop from 1,200 feet AGL to 700 feet AGL in these areas? Think of it like Class B or C airspace, it drops down to protect aircraft on approach or departure from an airport.

Class E Airspace: Controlled airspace which is neither class A, B, C nor D. In most areas of the United States, class E airspace extends from 1,200 feet (370 m) above ground level (AGL) up to but not including 18,000 feet (5,500 m) MSL, the lower limit of Class A airspace.

Perhaps the most misunderstood airspace category, Class Echo (E) starts at 14,500'MSL and extends up to but not including 18,000' (bottom of Alpha Airspace) over the entire continental United States unless otherwise depicted. It also exists above Alpha (above 60,000').

Class E Surface Area is depicted on the sectional with a dashed magenta line – – – – -. Sometimes Class E airspace goes all the way down to the surface of the ground. This is called Class E surface area. In general, we don't need permission to fly in Class E airspace.

Class E Airspace Requirements Basic VFR minimums are 3sm visibility, 500' below clouds, 1,000' above clouds, 2,000' horizontal from clouds.

MORE DETAILS

Class E airspace consists of all controlled airspace that is not associated with Class A, Class B, Class C, or Class D airspace. This airspace is typically found around airports that do not have an operating control tower or en route airspace above 700 feet AGL or 1,200 feet AGL.

MORE DETAILS

Class Echo Airspace: 250 knots below 10,000' MSL within class echo airspace. While operating in the traffic pattern at an airport without an operating control tower, it is recommended that the pilot maintain an airspeed of no more than 200 KIAS.

On a map, Class G's ceiling is the floor of Class E airspace. And, it's always exclusive. For example, if Class E starts at 700 feet AGL, Class G goes up to, but doesn't include, 700 feet AGL. Class G airspace is most easily found on a sectional map when a fading, thick blue line appears.
