Central Altitude Reservation Function (CARF)

The Federal Aviation Administration (FAA) Air Traffic Control (ATO) Central Altitude Reservation Function (CARF) system operates under authority 49 U.S. Code § 40101. It is a system for coordination of Altitude Reservation (ALTRV) requests and special military operations, both nationally and internationally. The FAA CARF Office is responsible for coordinating military and civilian ALTRVs for operations that depart their area of jurisdiction and for ALTRVs that operate within US-controlled airspace. Altitude reservations are used for mass movement of aircraft or special requirements, which cannot be met satisfactorily without an altitude reservation. The majority of ALTRVs are requested by the Department of Defense (DoD). The FAA is publishing this Privacy Impact Assessment (PIA) for CARF in accordance with Section 208 of the E-Government Act of 2002 because the system collects Personally Identifiable Information (PII) from members of the public, specifically representatives of private companies requesting Altitude Reservations.
