Are Unmanned Aircraft (UA) operations allowed in Class C airspace?

Unmanned Aircraft (UA) operations are indeed allowed in Class C airspace with ATC (Air Traffic Control) permission. In Class C airspace, ATC provides services to both manned and unmanned aircraft, ensuring safe and orderly traffic management. Before a UA can operate in this airspace, the operator must receive authorization from ATC, which may include the need to maintain communication and adhere to specific operational rules. This regulatory framework is designed to integrate UAs into the existing airspace structure while maintaining safety for all users.

The other options imply restrictions or prohibitions that do not align with the operational regulations governing UAs in Class C airspace. For instance, stating that operations are not allowed "under any circumstances" or only during specific hours does not reflect the flexibility that ATC provides for UA operations. Similarly, requiring FAA clearance alone overlooks the direct role of ATC in managing airspace use by unmanned systems.
