Federal Aviation Administration (FAA) Data Communications (Data Comm) User Information

Data Comm Overview

The FAA's NextGen Data Comm program allows the National Airspace System (NAS) to handle more traffic, reduce flight delays, route aircraft more efficiently and improve safety, all while reducing operational costs for airspace users. In today's NAS, air traffic management depends on voice communications to relay a wide array of critical information between air crews and controllers. As a trusted partner with the FAA, L3Harris is lending its expertise to enhance safety and improve efficiency in the nation's airspace.

Air-to-Ground Data Communication: Making Air Traffic Control Modernization Possible

Data Comm improves aviation safety by reducing errors common in voice communications such as readback/hearback errors, control instructions intended for one aircraft taken by another and transposed call signs. It increases airport efficiencies by providing revised departure clearances at busy hub airports, and it makes airspace safer and flight more efficient through capabilities such as trajectory-based operations, continuous descent approaches and dynamic weather reroutes.
