In response to a request from the FAA, the RTCA Chairman’s 
Committee produced a NEXCOM report that identifies issues 
attendant with transitioning Air Traffic Control communications 
to a digital voice and data communications system.  The 
Chairman’s Report, completed in August 2000, provides 
observations and recommendations that highlight the need for a 
systems approach in addressing issues of spectrum, policy, 
procedure, acquisition, certification, training, facilities, 
and maintenance.  This document reports the actions being taken 
by the FAA, SC-198, and the NEXCOM Aviation Rulemaking 
Committee that address these observations and recommendations.
