AIM ¶ 5-6-12 — ESCAT Procedures
AIM 5-6-12 explains ESCAT procedures: how the military and ATC direct VFR/IFR flights during defense emergencies. Study guide for pilot checkrides.
ESCAT (Emergency Security Control of Air Traffic) is a joint military-FAA plan that activates during a defense emergency or air defense emergency. Authorized under 32 CFR Part 245, ESCAT lets the military direct landing, grounding, diversion, or dispersal of civil aircraft to defend U.S. airspace.
When ESCAT is implemented (in whole or in part), the Air Traffic Control System Command Center (ATCSCC) issues instructions that ATC facilities broadcast on available frequencies. As a pilot, here's what to expect:
- VFR flights may be directed to land at the nearest available airport.
- IFR flights are expected to proceed as directed by ATC.
- Pilots on the ground may need to file a flight plan and obtain FAA approval before any flight operation.
Operationally, this means monitoring ATC frequencies closely during heightened national security conditions and being ready to comply immediately. ESCAT is rare but critical — failing to follow instructions during an actual activation could compromise national defense and result in interception.
