Study Notes

Class E Airspace Overview

Class E airspace has three possible lower limits where it can start: at the surface, at 700 feet AGL, and at 1,200 feet AGL.
It is present almost everywhere, making it a vital airspace type for pilots to understand.

Class E Airspace Characteristics

Class E airspace at the surface is outlined with closed-off magenta dashed lines, which appear as circles with extensions.
For Class E airspace starting at 700 feet AGL, the outline is depicted using a thick, shaded magenta line.

FAA Authorization Requirements

FAA authorization is required for flying in core Class E airspace, including the Class E extension and the Class E airspace circle.
In contrast, if the Class E airspace extension is not part of the Class E airspace circle, no FAA authorization is needed to fly in it.

Flying Around Class E Airspace

It is permissible to fly around Class E airspace that starts at 700 feet AGL, as the area below this height remains Class G uncontrolled airspace.
When situated near a tower in Class E airspace at 700 feet AGL, pilots can fly in proximity without needing FAA authorization if they adhere to specific conditions, including maintaining a 400-foot radius and not exceeding 400 feet above the structure's limit.

Identification and Limitations

Class E airspace starting at 1,200 feet AGL lacks explicit markings, making identification crucial for pilots.
This airspace encompasses regions outside controlled Class E airspace that begins at 1,200 feet AGL.
The upper limit of Class E airspace can range from the lower boundary of Class B or C airspace to a maximum of 18,000 feet MSL.

Ground Level Considerations

If an aircraft lands at an airport located within Class E airspace, it operates in Class G uncontrolled airspace as it descends below 700 feet AGL, where Class E airspace does not extend to the ground.

Specific Airspace Scenarios

For airspace surrounding Barnes County Airport, it is classified as Class G airspace from the surface to 700 feet AGL, as the airport's airspace begins at 700 feet AGL and cannot be said to overlay or surround within the lower levels.
