5 Key Takeaways

It's Invisible to Standard Apps

FDC 6/4375 creates a moving TFR that does not appear on B4UFLY, LAANC, or AirMap. You cannot pre-check it the way you would a stadium TFR.

It Follows Federal Assets

Any DoD, DOE, DOJ, or DHS ground vehicle or convoy triggers a 3,000 ft lateral / 1,000 ft vertical no-fly bubble that moves with it in real time.

Zero Tolerance Enforcement

Accidental violations are treated the same as intentional ones. Penalties include up to $75,000 in fines, certificate revocation, and criminal prosecution.

Your Legal Ceiling Is Inside It

Flying at the standard 400 ft AGL ceiling puts you automatically within the 1,000 ft vertical standoff zone if a federal asset is anywhere nearby.

Ground Scanning Is Now Pre-Flight

Before every flight, operators must visually scan for unmarked federal vehicles, check local news for federal activity, and document airspace clearance with a screenshot.

Criminal exposure: Violations may be prosecuted as federal crimes. Under FAA Bulletin 2026-1, the burden of proof is shifted — operators are presumed to have known about the restriction. Federal agents are authorized to intercept, seize, or destroy drones in violation.
