Statement of Policy on Performance Requirements for Operators of Aircraft That are Equipped With Automatic Dependent Surveillance-Broadcast (ADS-B) Out

This action announces the FAA's policy on performance requirements for certain operations of aircraft with Automatic Dependent Surveillance-Broadcast (ADS-B) Out equipment in ADS-B airspace after January 1, 2020. Under the circumstances identified in this policy, the FAA is providing assurance to operators that it will not consider degradation in Global Positioning System performance due to conditions outside the operator's control that results in an operation falling below ADS-B rule requirements to constitute non- compliance, provided the operator has exercised appropriate due diligence prior to conducting an operation.
