Temporary Flight Restrictions and Flight Limitations
Temporary Flight Restrictions (TFRs) — the kinds of TFRs, why they’re issued, and how to find and comply with them.
About this document
AC 91-63, Temporary Flight Restrictions and Flight Limitations, explains the airspace restrictions the FAA puts in place temporarily — for hazards, special events, VIP movement, and national-security reasons. It describes the regulatory basis for each TFR type (such as 91.137, 91.138, 91.141, and 91.145), what they prohibit, and how pilots learn about them through NOTAMs and preflight briefings.
