The FAA's NextGen Data Communications program will allow the National Airspace System to handle more traffic, reduce flight delays, route aircraft more efficiently, and enhance safety all while reducing operational costs for airspace users. In today's National Air Space (NAS) air traffic managment depends on voice communications to relay a wide array of critical information between air crews and controllers. The use of voice communications is labor intensive, time consuming and limits the ability of the NAS to effectively meet future traffic demands. Data Communications will enhance today’s operations 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 Communications will increase airport efficiencies by providing revised departure clearances at busy hub airports. In the en route airspace, capabilities such as trajectory-based operations, continuous descent approaches, and dynamic weather reroutes can be enabled using Data Communications.
The FAA’s DataComm program will provide the infrastructure to make NextGen a reality.
