The NextGen Advisory Committee (NAC), established in 2010 to address the task force recommendation to continue industry collaboration, is a federal advisory group comprising aviation stakeholders formed to provide advice on policy-level NextGen implementation issues facing the aviation community. The FAA and NAC in 2014 agreed on the NextGen Priorities Joint Implementation Plan to accelerate delivery of four core NextGen initiatives over three years to improve efficiency: optimizing airports with multiple runways (e.g. via simultaneous parallel landings with reduced separation), increasing the efficiency of surface operations, reconfiguring the navigation system from ground-based to primarily satellite-based, and improving communications between aircraft and the ground through a digital system.
