Plain English Meaning

Controlled airspace that fills in the areas not covered by the busier classes. IFR pilots get ATC separation here; VFR pilots can fly through without talking to anyone, as long as the weather is good enough.

Full Definition

Controlled airspace that is not designated as Class A, B, C, or D. It typically begins at 700 feet or 1,200 feet above the surface (or at the surface in some areas around airports without an operating control tower) and extends up to, but not including, 18,000 feet MSL. Class E airspace exists to provide ATC separation services for IFR traffic, while VFR traffic may operate without ATC clearance provided the appropriate weather minimums are met.
