Description / Abstract: 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.
