What does Class E airspace typically represent?

Class E airspace generally encompasses airspace that extends from either 700 feet above ground level (AGL) or from 1,200 feet AGL, up to 17,999 feet mean sea level (MSL). This classification is specifically utilized for various purposes, including to facilitate instrument flight rules (IFR) operations and to provide controlled airspace for certain areas without the more stringent regulations that apply to the higher classifications like Class A or B airspace.

The correct answer indicates the vertical limits of Class E airspace, showcasing its role as a transition space that accommodates both visual flight rules (VFR) and IFR operations, with the intention of ensuring a safe and organized flow of air traffic. This structure helps to manage air traffic in busy areas while allowing for flexibility and access at lower altitudes.

Understanding the nature of Class E airspace is crucial for unmanned aircraft operators, as it informs them of the specific regulations and operational considerations, such as needing to establish communication with air traffic control when operating in these areas, especially during controlled operations.
