A shaded magenta line on a sectional aeronautical chart indicates that Class E airspace begins at 700 feet above ground level (AGL). This type of airspace is typically designated in areas where controlled airspace is necessary to accommodate aircraft operations, and it serves to provide containment for those operations at lower altitudes.

The shaded magenta line signifies a transition from uncontrolled airspace to controlled airspace; when you cross this boundary while flying, it is essential to be aware that certain regulations and communication requirements apply. This is particularly important for drone pilots, as they must understand the airspace classifications in order to operate safely and legally within these regions.

In contrast, the other altitude indications described do not correspond with the shaded magenta line's purpose. Class E airspace may begin at different altitudes in other contexts, such as 1,200 feet or higher, but those are represented differently on the charts. Understanding the specific meaning of the shaded magenta line helps pilots navigate and comply with regulations pertaining to airspace usage.
