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 of the FAA, Harris 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 will improve 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.

Data Comm will increase airport efficiencies by providing revised departure clearances at busy hub airports, and it will make airspace safer and flight more efficient through capabilities such as trajectory-based operations, continuous descent approaches and dynamic weather reroutes.
