AIM Text
- Stationary or Moving Altitude Reservation (ALTRV). A Stationary or Moving ALTRV is announced via an airspace NOTAM issued by the Central Altitude Reservation Facility (CARF) or ARTCC. These announcements will appear in CARF and/or ARTCC NOTAMS. This airspace ensures non-participating IFR aircraft remain separated from special activity. Non-participating VFR aircraft are permitted to fly through the area but should exercise vigilance.
- ATC ASSIGNED AIRSPACE. Airspace of defined vertical/lateral limits, assigned by ATC, for the purpose of providing air traffic segregation between the specified activities being conducted within the assigned airspace and other IFR air traffic. ATCAA locations and scheduled activation information can be found on the FAA SUA website; a NOTAM will not be issued to announce the activation of this airspace.

Research Notes
AIM 3-5-10 covers National Security and Interception Procedures (parallel reference to AIM 4-6).
The interception sequence (review):
- Interceptor positions visually
- Signals: rocking wings = "you've been intercepted"
- Pilot acknowledges by rocking wings
- Pilot contacts ATC on 121.5
- Pilot follows interceptor's instructions (typically land at directed airport)
Key principle: Comply immediately. Don't try to outrun, maneuver aggressively, or claim emergency to evade. The interceptor is enforcing aviation security on behalf of national authorities.
