AIM ¶ 5-6-2 — National Security Requirements
AIM 5-6-2 explains national security rules for ADIZ, Defense Areas, TFRs, and NSAs. Study guide for pilot students prepping for checkrides and oral exams.
AIM 5-6-2 explains the national security rules that apply any time you fly in U.S. territorial airspace, an Air Defense Identification Zone (ADIZ), or a Defense Area. Under 14 CFR 99.7, you must comply with special security instructions issued by the FAA in coordination with the DoD or U.S. security/intelligence agencies — in addition to all other applicable Part 91 and Part 99 rules.
Because security postures change frequently, 14 CFR 91.103 (Preflight Action) requires you to become familiar with all available information before flight. That includes checking NOTAMs for:
- TFRs under 91.137 (disaster/hazard areas)
- TFRs under 91.138 (Hawaii national disaster areas)
- TFRs under 91.141 (Presidential and VIP movements)
- TFRs under 91.143 (space flight operations)
- National Security Areas (NSAs) that may be temporarily converted to prohibited airspace under 99.7
Why it matters: Noncompliance can lead to denial of entry, a ground stop, interception by military aircraft, or detention and interview by law enforcement. A thorough NOTAM and TFR review during preflight is your best defense.
