You’ll encounter Class E airspace on nearly every flight during your training—whether you’re practicing slow flight and stalls near your local airport or heading out on a longer cross-country journey. Unlike the clearly defined boundaries of Class B, C, or D airspace, Class E can feel invisible on a sectional chart, which sometimes leaves student pilots scratching their heads. While it’s controlled airspace monitored by ATC, you don’t need clearance to fly in Class E as long as the weather meets basic visual flight rules (VFR).
Because Class E is essentially “everywhere,” knowing its limits is key—especially the floor and ceiling. The top is straightforward: Class E ends at 17,999 feet MSL, where Class A airspace begins, reserved for high-altitude traffic like commercial airliners. Understanding these boundaries early will help you fly confidently and stay on the right side of the rules.
Class E airspace typically doesn’t reach down to the ground. In flat areas (non-mountainous terrain), the lowest part of Class E airspace usually starts 700 feet or 1,200 feet above the ground level (AGL). But how can you know the difference? You can determine this by looking at sectional charts, which provide details about the boundaries of different airspaces.
The answer lies within the faded magenta circle that typically surrounds nontowered airports. In the example above, the floor of Class E is 700′ on the faded side of the border (the airport surface area) and 1,200′ everywhere else. Stay below the floor of Class E airspace and you’ll remain in Class G airspace and take advantage of the less restrictive cloud clearance and visibility minimums.
Speaking of weather requirements, here’s a summary of the minimum cloud clearance and visibility required to operate in Class E airspace:
As with all things in aviation, there are many exceptions to the standard conventions. Here are some examples of Class E floor variations found throughout the US.
In this case, Class E extends to the surface, as identified by the dashed magenta line/box appearing adjacent to the Class D airspace:
In some cases, the surface area for an airport is designated as Class E airspace, which is identified by the dashed magenta line/circle around the airport:
Next, let’s review Class E airspace around federal airways. In this example around Victor 120, Class E airspace starts at 1,200′ AGL inside the blue feathered area and extends all the way to the Class A airspace above. The areas outside of the hard edge of the blue line are Class G airspace from the surface to 14,500′ MSL, and then Class E above that:

“While Class E airspace is considered controlled airspace, you do not need an ATC clearance to fly in it.”
Many times the weather at my 3500-foot MSL surface class echo airport is below Class E minimums but just beyond the Class E airspace it’s great VFR and an ATC clearance is required. If you are arriving at or departing from an airport marked with surface class echo airspace and the weather is less than a 1000 foot ceiling and/or less than 3 miles, then an ATC clearance is required to fly in that Class Echo airspace.
