ATO Block Aircraft Registration Request (BARR) Program: The BARR program protects the legitimate privacy and security interests of General Aviation (GA) aircraft owners, operators, and their passengers. The program is the single point of contact for individuals and groups who want to block the display of their flight information The program develops and maintains agreements with data users to accomplish data sharing in accordance with the agency's mandate to protect their privacy. The BARR program ensures release of flight information and data from the data feed is not comprised and that the availability of the information to the FAA and law enforcement agencies is not diminished.

On November 18, 2012, the President signed into law H.R. 2112, the "Consolidated and Further Continuing Appropriations Act, 2012." This statue amends the previous entitled Security Concerns Blocking policy in which aircraft owners or operators can limit the dissemination of their aircraft data in the FAA ASDI data feed.

The FAA proposed and solicited comments on procedures for all aircraft owners and operator requests for ASDI blocking prior to enacting new, specific policy changes in order to comply with the new law. In the interim, the following procedures are in effect:

The FAA will be withdrawing the Certified Security Concerns Blocking program policy.

Any aircraft on the ASDI block list, either by virtue of the Certified Security Concern program, or as a request submitted under the FAA's Interim ASDI block policy, after June 3, 2011, will remain blocked.
Thus, it is not necessary for the owners or operators of these aircraft to submit their initial request again, unless they wish to change the blocking status of their aircraft or amend the level at which their aircraft is blocked.

The FAA will accept and implement all direct requests of aircraft owners or operation to block their aircraft data from public display, including those not accompanied by a Certified Security Concern.

It is the FAA's intention to make the aircraft blocking process as simple as possible. As a result, and until further notice of the updated Federal Register's imminent publication date, the process related to aircraft blocking and unblocking requests will remain unchanged. When an aircraft owner or operator submits a blocking request, minimum information should specify the registration number of the aircraft, whether the requestor is an owner or operator of the aircraft, a telephone number and/or electronic mail address to which the FAA can direct questions about the request, and whether the requestor desires ASDI blocking at the (a) FAA data source or at the (b) ASDI subscriber level. Any requests that do not specify with of these levels (a or b above) are preferred will be blocked at the FAA data source.

ASDI block requests may still be submitted via electronic mail address at:

ASDI blocking request may also be submitted via regular mail to:

FAA ASDI Blocking Requests
ATO System Operations Services, AJR-0
Wilber Wright Building, Room 3E1500
600 Independence Avenue SW
Washington, DC 20597

The existing ASDI MOA will remain in effect insofar as it requires ASDI subscribers to block requests based upon Certified Security Concerns and further, that the FAA construes the MOA to obligate ASDI Subscribers to filter any other aircraft data at the direction of the FAA.

Block Lists are implemented on the first Thursday of each month, and the request cutoff date is the 15th of the preceding month.

A final FAA ASDI Policy proposal will be announced via the Federal Register in CY13.
