Which publication is the primary source for identifying Temporary Flight Restrictions (TFRs) and other current airspace restrictions before a drone flight?
Why →
NOTAMs are the official real-time notification system for temporary hazards and restrictions including TFRs, runway closures, and NAVAID outages. TFRs created under §§ 91.137–91.145 are published as NOTAMs. Sectional charts and the AIM are updated on fixed cycles and cannot reflect temporary conditions.The trap →
Sectional charts are updated every 56 days and cannot show TFRs. The AIM is a procedures reference, not a flight planning tool for current conditions. Only NOTAMs and real-time apps pulling live NOTAM data give current airspace status.SOURCE → FAA AIM Chapter 5 / 14 CFR Part 91CHECKED APR 21ACS II.B.K3MED
