What is the definition of a temporary flight restriction (TFR)?

The definition of a temporary flight restriction (TFR) is a restriction on certain aircraft from operating in a defined area on a temporary basis. TFRs are typically implemented to address specific safety or security needs, such as during major events or emergencies. They can restrict access to airspace for various aircraft types and are designed to protect people on the ground, ensure safety during special circumstances, or facilitate airspace management.

The correct understanding of TFRs is crucial for operators and air traffic control personnel because adherence to these restrictions is essential for maintaining safety in the aviation system. TFRs are not permanent bans; rather, they are time-sensitive limitations that help manage airspace effectively in response to particular situations.
