Class E airspace can be one of the most complex airspace types to visualize, as it doesn’t always start at the same altitude and isn’t always clearly marked. For private pilots, instrument rating candidates, and certified flight instructors, a solid understanding of Class E is essential for safe airplane navigation. Class E often begins at either 700 feet or 1,200 feet AGL, depending on sectional chart shading, and extends up to but not including 18,000 feet MSL.
Identifying Class E Airspace on a Sectional Chart
On VFR sectional charts, shaded magenta areas indicate Class E starting at 700 feet AGL, while unshaded areas typically begin at 1,200 feet AGL. Victor airways, depicted as blue shaded lines, are also Class E and run from 1,200 feet AGL to just under 18,000 feet MSL. Class E surface areas provide controlled airspace at airports without control towers, supporting IFR arrivals and departures.
Weather Minimums and Operating Tips
When flying VFR in Class E airspace below 10,000 feet MSL, you must maintain at least 3 statute miles visibility, stay 500 feet below clouds, 1,000 feet above clouds, and 2,000 feet horizontally from clouds. While no special pilot certification is required to enter Class E, ATC separation services aren’t provided for VFR flights. Instructors often use “rocket ship” scenarios—imagining a climb from the ground up—to help students visualize changing airspace layers.
