## Abstract

This action clarifies FAA policy regarding the existing accuracy requirements for the reported geometric altitude of the control station of a standard remote identification unmanned aircraft. The FAA describes one acceptable way producers of unmanned aircraft can meet the minimum performance requirement for the accuracy of the control station's reported geometric altitude. The FAA determined that this action is necessary to inform developers of means of compliance of one potential pathway to meet the performance requirement for the control station's reported geometric altitude.
