During ESCAT, who must grant approval?

During the Emergency Special Category Air Traffic (ESCAT) operations, the responsibility for granting approval lies with Air Traffic Control or the Flight Service Station. This is because these entities are directly involved in managing and coordinating air traffic in emergency situations. They have the authority and the necessary tools to assess aircraft movements, prioritize safety, and communicate effectively with pilots and other relevant parties during unusual or heightened alert conditions.

Air Traffic Control plays a critical role in maintaining the safe and orderly flow of air traffic, particularly in complex environments where aviation operations must be modified due to emergency situations. The Flight Service Station also supports this by providing relevant information and services to pilots, ensuring they are aware of procedures and requirements that must be followed during ESCAT.

The other choices relate to organizations that may have roles in aviation but do not possess the authority to grant the specific approvals required during ESCAT. The Aeronautical Information Service provides data essential for safe flight planning but is not involved in emergency control operations. The Department of Transportation oversees transportation policy but does not interact with individual flights during emergencies. Similarly, the Aircraft Owners and Pilots Association focuses on advocacy, education, and resources for pilots rather than direct air traffic management.
