Blocking Display of Aircraft Situation Display to Industry (ASDI) Data

Bookmark and Share

On August 21, 2013, the FAA issued a final notice in the Federal Register for the process of limiting the diplay of aircraft situation display to industry (ASDI) data. These procedures took effect on September 20, 2013. This was formerly known as the Blocked Aircraft Registration Request (BARR) program administered by NBAA.

Federal Register Notice: Final Notice of the Process for Limiting Aircraft Data Displayed Via ASDI.

The notice explains that aircraft owners and operators may request blocking of their flight tracking information allowing aircraft owners and operators to “opt out” from having their ASDI flight information broadcast over the Internet.

For more informartion on the process to block and unblock aircraft, review the resouces below.

Blocking Requests

Unblocking Requests

The FAA manages this program and NBAA no longer has any policy or administrative control over the FAA ASDI Block program. However, if you have general questions or concerns about the FAA process, contact NBAA's Operations Service Group at ops@nbaa.org or (202) 783-9250.

Blocking Requests

Determine the Appropriate Blocking Level

There are two levels of ASDI blocking:

  1. ASDI Subscriber Level Blocking
  2. FAA Source Blocking

Operators should carefully review the information below to understand the differences between each option. It is important to specify the desired blocking level in any requests to FAA. Requests that do not include a preferred blocking level will be processed at the FAA Source level by default.

ASDI Subscriber Level Blocking

Under ASDI Subscriber Level Blocking an operator’s flight tracking data is still broadcast from FAA to the ASDI providers (i.e. flight tracking vendors). However, the providers are bound by a letter of agreement to not publically display information for aircraft on the blocked list. This option allows operators to track their own aircraft through the ASDI vendor of their choice.

To track their own aircraft, the operator must contact the ASDI provider and request that the tracking information be selectively unblocked. Note that some ASDI providers may charge for this service.

Review the FAA's list of current ASDI vendors.

FAA Source Blocking

Using FAA Source Blocking, an operator’s ADSI data is not broadcast from the FAA to the ASDI vendors at all. Aircraft operators considering the FAA-level block should remember that they will not be able to track their own aircraft via an ASDI vendor once the FAA block is in place.

Required Information for Blocking Requests

To assist the FAA in processing aircraft owner or operator requests promptly, all requests related to an aircraft’s ASDI blocking or unblocking must include the following information:

  • The name of the requestor
  • the registration numbers or call signs of the aircraft to be blocked
  • a statement in the certification request that the requestor is the owner or operator of the specified aircraft or is a legally authorized representative of the aircraft owner or operator
  • a telephone number or email address to which the FAA can direct any questions about the request
  • a statement indicating the requestor’s desired level of ASDI blocking: either "ASDI Subscriber Level Blocking" or "FAA Source Blocking."

How to Submit Blocking Requests

The FAA’s primary electronic mailbox for all aircraft blocking and unblocking requests and for related inquiries directed to the ASDI blocking program is ASDIBlock@faa.gov.

The FAA also will accept hard-copy aircraft block requests submitted by regular mail at:

FAA ASDI
Blocking Request; ATO System
Operation Services, AJR–0; Wilbur
Wright Building, Room 3E1500
600 Independence Avenue SW; Washington, DC 20597

Processing Time for Blocking Requests

The FAA implements the ASDI block list updates on the first Thursday of each month. As a result, requests that the FAA receives on or before the 15th of the preceding month are likely to be processed in time to take effect in the month after the FAA receives them. However, it is possible that the volume of requests in a given month, a requestor’s timeliness, or issues with the completeness and accuracy of the information that the FAA receives could preclude the FAA from processing some requests in time for them to take effect in the month following their submission. In that event, the FAA will process all requests in the order in which the FAA receives them, to the extent that it is possible.

There is no renewal requirement – once an aircraft has been processed for blocking it remains blocked indefinitely or until the operator submits an unblocking request to the FAA.

Unblocking Requests

Requests to remove ASDI blocking at the ASDI subscriber level or the FAA source must include the following informtion:

  • aircraft owner or operator name
  • a telephone number or email address to which the FAA can direct any questions about the request
  • the registration numbers or call signs of the aircraft to be unblocked

The FAA’s primary electronic mailbox for all aircraft unblocking requests and for related inquiries directed to the ASDI blocking program is ASDIBlock@faa.gov.

The FAA also will accept hard-copy aircraft unblock requests submitted by regular mail at:

FAA ASDI
Blocking Request; ATO System
Operation Services, AJR–0; Wilbur
Wright Building, Room 3E1500
600 Independence Avenue SW; Washington, DC 20597

Please note that if your company sells an aircraft that is on the FAA ASDI block list you should inform the new owner of the ASDI block status of the aircraft, or request removal of the aircraft from the FAA ASDI block list after the sale.
