## Abstract

This document amends the Commission's rules to specify that very high frequency (VHF) aeronautical stations operating with phase modulation digital data emissions shall limit their power and out-of- band emissions in accord with recently modified international Standards and Recommended Practices (SARPs) adopted by the International Civil Aviation Organization (ICAO). The Commission has adopted these amendments in response to a petition for partial reconsideration of the Report and Order in this proceeding, filed by Aeronautical Radio, Inc. (ARINC). These rule amendments will serve the public interest because the revised standards have been accepted by the aviation community globally and will assist the aviation industry in implementing new data communications systems. In addition, by facilitating the deployment of advanced aviation communications technology, these amendments will serve the goals of aviation safety and efficiency that underlie this proceeding.
