Generally, if the airspace is not Class A, B, C, or D, and is controlled airspace, then it is Class E airspace. Class E airspace extends upward from either the surface or a designated altitude to the overlying or adjacent controlled airspace.
Class E airspace is depicted in blue or magenta on sectional charts and white on low altitude enroute charts. For VFR operations basic VFR visibility and distance from clouds must be maintained. Below 10,000 MSL feet this is 3 statute miles visibility and 500 feet below, 1000 feet above, and 2000 feet horizontally.
