Temporary Flight Restriction Law and Legal Definition

The Federal Aviation Administration may also issue Temporary Flight Restrictions, or TFRs, which are similar to Prohibited Areas but which are typically effective for a few days or weeks, versus the essentially permanent nature of a Prohibited Area. For example, a TFR is typically issued to prohibit flights near the President's destination when he travels outside Washington. TFRs are also issued to ensure a safe environment for firefighting operations in the case of wildfires and for other reasons as necessary.
