Countries can set their own requirements for authorizations for ADS-B Out operations. The FAA has decided khổng lồ discontinue the ADS-B Out LOA (A153) & will no longer be issuing authorizations khổng lồ US operators. However, we recommend that US operators carry a copy of Notice 8900.491 lớn show to lớn foreign inspectors if they are requested khổng lồ provide their authorization. In essence, Notice 8900.491 is provided by the FAA to summarize why it is no longer providing authorizations for ADS-B Out. It is important to lưu ý that an LOA is still required for ADS-B In operations.

Setting the scene

Back in 2010, the International Civil Aviation Organization (ICAO) determined that operators needed lớn request operational approval for Automatic Dependent Surveillance-Broadcast (ADS-B) Out from their Civil Aviation Authority (CAA). While the FAA had not required an LOA khổng lồ use ADS-B Out in the United States, they had issued OpSpec/MSpec/LOA A153 or A353 lớn satisfy foreign CAAs that did require authorization.

However, in September 2015, ICAO thành viên States adopted new guidance that gradually phased out operator authorization requirements to lớn use ADS-B Out. As stated in Notice 8900.491, “continuous monitoring of equipment performance has proven lớn be the most effective means of oversight.” By overseeing the data of ADS-B Out, the FAA & other CAAs can identify aircraft performance. Any aircraft with a negative safety impact on Air Traffic Control could be restricted from flying in airspace requiring ADS-B Out. Additionally, with rising demand in OpSpecs, MSpecs, and LOAs, the FAA has become understandably stretched. Removing the need for any LOA can help minimize the burden placed on both regulators và operators.

What’s changing for the ADS-B Out LOA và what should I do?

In short, the FAA has decommissioned OpSpecs/MSpecs/LOA A153 & A353, also known as the ADS-B OutLOA. By June 30, 2019, the FAA will have reached out lớn operators currently holding these OpSpecs/MSpecs/LOAs lớn inform them that it is no longer necessary. However, it’s strongly advised khổng lồ carry a copy of Notice 8900.491 on the aircraft. If any foreign inspectors or officials ask about the LOA, operators can show the Notice explaining why the FAA is no longer issuing an authorization.

Different airspace will have different regulations, so be sure lớn research equipage requirements when planning your overseas journey anyway – especially in regard to the ADS-B Out mandate. No further kích hoạt should be needed from pilots and operators as we understand it.

For operators carrying our International Operations & Procedures Manual, no immediate revisions are needed, but we will be covering this in our next International Operations và Procedures Manual Revision Service update, so keep an eye out.

We want to again emphasize that all of this applies only lớn ADS-B Out. ADS-B In continues to lớn require an LOA.
