Navigating Temporary Flight Restrictions (TFRs) can be one of the trickier parts of flight planning, especially as they often pop up with little notice and cover a wide range of events — from major sporting events and natural disasters to VIP travel. This FAA Safety Briefing article highlights common pitfalls pilots encounter with TFRs and offers practical tips to stay compliant, including checking multiple sources before flight, using trusted preflight briefings, and staying alert for pop-up restrictions enroute. While TFR violations are rare, they carry serious consequences, making it essential for pilots to know where to look and how to stay informed.
