Are UA operations allowed in Class E airspace?

Operations of unmanned aircraft (UA) in Class E airspace are indeed allowed but are subject to certain regulations that enhance safety and coordination with air traffic. Class E airspace typically serves as a transition between controlled and uncontrolled airspace, meaning that aircraft operating within this airspace should be aware of and adhere to specific rules.

When ATC permission is required, it ensures that both manned and unmanned aerial systems can coexist safely in the airspace. This permission may involve coordination regarding altitudes, flight paths, and any potential conflicts with other aircraft. While some areas within Class E may be more permissive regarding UA operations, the overarching requirement for ATC approval in certain circumstances reflects the need for careful oversight to ensure safety, particularly in busy or complex airspace environments.

The other options suggest either unrestricted operations, which can compromise safety, or outright prohibitions, which do not align with current regulations allowing for UA operations when proper protocols are followed. Therefore, the requirement for ATC permission ensures a structured approach to integrating unmanned aircraft into the National Airspace System.
