What is a Special Flight Rules Area (SFRA) and how does it differ from a standard TFR?

Why →A Special Flight Rules Area (SFRA) is a permanent airspace designation established by rule (not by NOTAM) requiring pilots to comply with specific operating procedures. The most notable SFRA in the United States is the Washington D.C. SFRA, which extends 30 NM from the DCA VOR and requires all flight to comply with strict authorization and transponder requirements, including drone operations.

The trap →TFRs are temporary (issued by NOTAM, valid for limited periods). SFRAs are permanent regulatory designations established by rulemaking. The Washington D.C. SFRA is the most critical drone knowledge test topic. It is not a TFR and does not expire.

Field note →The D.C. SFRA's inner ring (15 NM radius) is a Flight Restricted Zone (FRZ) where drone operations require explicit FAA authorization coordinated with DC Air Defense. The outer ring (15–30 NM) is the SFRA proper with somewhat less restrictive but still mandatory authorization requirements. This area generates significant FAA enforcement.
