What type of airspace requires special permission for drone operations?

Controlled airspace, such as Class B, C, D, and E, requires special permission for drone operations because these areas are designated to manage traffic and ensure safety for all users of the airspace, including manned aircraft. Each class of controlled airspace has specific conditions and operational requirements that pilots need to adhere to.

For instance, Class B airspace surrounds major airports and has the highest level of air traffic control; therefore, operating a drone within this space necessitates getting clearance from air traffic control. Similarly, Class C and D airspaces require communication with the respective air traffic control facilities. Class E airspace, while generally less restrictive, still often requires certain regulations be followed, depending on the altitude and location.

In contrast, unrestricted airspace typically does not have these stringent requirements, and operations can often be conducted without special permissions. Areas over water may also fall outside of controlled airspace and thus may not require the same level of oversight as land-based operations. Private property airspace pertains more to land ownership than airspace operations, meaning that permission from the property owner does not necessarily equate to permission regarding air traffic control regulations. Thus, the need for special permission in controlled airspaces is crucial to maintain safety and order in areas
