Pilot's Handbook of Aeronautical Knowledge Practice Test

Temporary airspace restrictions are issued to keep the airspace safe around events or emergencies for a limited time. This acronym stands for Temporary Flight Restriction. They’re published in NOTAMs and specify the area, duration, and any flight limitations, so pilots know to avoid the area or obtain authorization before operating. TFRs are used for things like VIP movements, natural disasters, wildfire response, or major public events. The other terms aren’t used in aviation to describe this concept—Terminal Flight Restriction, Terrain Flight Restriction, and Transient Flight Regulation don’t match how these temporary, location-specific airspace restrictions are defined.
