A Temporary Flight Restriction (TFR) is a regulatory action that prohibits certain aircraft from flying in a designated area for a specific period. TFRs are often implemented for safety reasons, such as during natural disasters, large public events, or when there are security concerns. They help ensure the safety of both the public and the aircraft involved. TFRs are issued by the Federal Aviation Administration (FAA) in the United States and are communicated to pilots through notices and charts. Pilots must comply with these restrictions to avoid penalties and ensure safe airspace management. Violating a TFR can lead to serious consequences, including fines or loss of flying privileges.
