A Temporary Flight Restriction (TFR) is a designated block of airspace with specified dimensions where flight is temporarily restricted or prohibited. TFRs are put in place for reasons such as protecting people and property on the ground, providing a safe environment for disaster-relief or firefighting operations, or securing the airspace around special events or VIP movements. They are announced to pilots through NOTAMs (Notices to Air Missions), so checking NOTAMs before every flight is essential. Think of it as a temporary "no-fly bubble" that can pop up over wildfires, stadiums, or presidential visits.
